connecting rods (after removing the cylinder
head and sump) without removing the engine.
However, this is not recommended. Work of
this nature is more easily and thoroughly
completed with the engine on the bench, as
described in Chapter 2D.
2 Compression test-
description and interpretation
2
1 When engine performance is down, or if
misfiring occurs which cannot be attributed to
the ignition or fuel systems, a compression
test can provide diagnostic clues as to the
engine’s condition. If the test is performed
regularly, it can give warning of trouble before
any other symptoms become apparent.
2 The engine must be fully warmed-up to
normal operating temperature, the oil level
must be correct and the battery must be fully
charged. The aid of an assistant will also be
required.
3 On fuel injection engines, refer to Chap-
ter 12 and remove the fuel pump fuse from the
fusebox. Now start the engine and allow it to
run until it stalls.
4 Disable the ignition system by
disconnecting the multi-plug from the DIS or
E-DIS ignition coil. Remove all the spark plugs
with reference to Chapter 1 if necessary.
5 Fit a compression tester to the No 1
cylinder spark plug hole - the type of tester
which screws into the plug thread is to be
preferred.
6 Arrange for an assistant to hold the
accelerator pedal fully depressed to the floor,
while at the same time cranking the engine
over for several seconds on the starter motor.
Observe the compression gauge reading. The
compression will build up fairly quickly in a
healthy engine. Low compression on the first
stroke, followed by gradually-increasing
pressure on successive strokes, indicates
worn piston rings. A low compression on the
first stroke which does not rise on successive
strokes, indicates leaking valves or a blown
head gasket (a cracked cylinder head could
also be the cause). Deposits on the underside
of the valve heads can also cause low
compression. Record the highest gauge
reading obtained, then repeat the procedure
for the remaining cylinders.
7 Due to the variety of testers available, and
the fluctuation in starter motor speed when
cranking the engine, different readings
are often obtained when carrying out
the compression test. For this reason, actual
compression pressure figures are not quoted
by Ford. However, the most important factor
is that the compression pressures are uniform
in all cylinders, and that is what this test is
mainly concerned with.
8 Add some engine oil (about three squirts
from a plunger type oil can) to each cylinder
through the spark plug holes, and then repeat
the test. 9
If the compression increases after the oil is
added, it is indicative that the piston rings are
definitely worn. If the compression does not
increase significantly, the leakage is occurring
at the valves or the head gasket. Leakage
past the valves may be caused by burned
valve seats and/or faces, or warped, cracked
or bent valves.
10 If two adjacent cylinders have equally low
compressions, it is most likely that the head
gasket has blown between them. The
appearance of coolant in the combustion
chambers or on the engine oil dipstick would
verify this condition.
11 If one cylinder is about 20 percent lower
than the other, and the engine has a slightly
rough idle, a worn lobe on the camshaft could
be the cause.
12 On completion of the checks, refit the
spark plugs and reconnect the HT leads and
the ignition coil plug. Refit the fuel pump fuse
to the fusebox.
3 Top Dead Centre (TDC) for No 1 piston - locating
2
1Top dead centre (TDC) is the highest point
of the cylinder that each piston reaches as the
crankshaft turns. Each piston reaches its TDC
position at the end of its compression stroke,
and then again at the end of its exhaust
stroke. For the purpose of engine timing, TDC
at the end of the compression stroke for No 1
piston is used. On the HCS engine, No 1
cylinder is at the crankshaft pulley/timing
chain end of the engine. Proceed as follows.
2 Ensure that the ignition is switched off.
Disconnect the HT leads from the spark plugs,
then unscrew and remove the plugs as
described in Chapter 1.
3 Turn the engine over by hand (using a
spanner on the crankshaft pulley) to the point
where the timing mark on the crankshaft
pulley aligns with the TDC (0) mark or TDC
reference pointer on the timing cover (see
illustration) . As the pulley mark nears the
timing mark, the No 1 piston is simultaneously
approaching the top of its cylinder. To ensure
that it is on its compression stroke, place a
finger over the No 1 cylinder plug hole, and feel to ensure that air pressure exits from the
cylinder as the piston reaches the top of its
stroke.
4
A further check to ensure that the piston is
on its compression stroke can be made by
first removing the air cleaner (refer to the
relevant Part of Chapter 4), then unbolting and
removing the rocker cover, so that the
movement of the valves and rockers can be
observed.
5 With the TDC timing marks on the
crankshaft pulley and timing cover in
alignment, rock the crankshaft back and forth
a few degrees each side of this position, and
observe the action of the valves and rockers
for No 1 cylinder. When No 1 piston is at the
TDC firing position, the inlet and exhaust valve
of No 1 cylinder will be fully closed, but the
corresponding valves of No 4 cylinder will be
seen to rock open and closed.
6 If the inlet and exhaust valves of No 1
cylinder are seen to rock whilst those of
No 4 cylinder are shut, the crankshaft will
need to be turned one full rotation to bring
No 1 piston up to the top of its cylinder on the
compression stroke.
7 Once No 1 cylinder has been positioned at
TDC on the compression stroke, TDC for any
of the other cylinders can then be located by
rotating the crankshaft clockwise (in its
normal direction of rotation), 180º at a time,
and following the firing order (see
Specifications).
4 Cylinder head rocker cover -
removal and refitting
1
Removal
1 Where necessary for access, remove the air
cleaner as described in the relevant Part of
Chapter 4.
2 Detach the HT leads from the spark plugs.
Pull on the connector of each lead (not the
lead itself), and note the order of fitting.
3 Remove the engine oil filler cap and
breather hose (where fitted).
4 Unscrew the four retaining bolts, and lift the
rocker cover clear of the cylinder head.
Remove the gasket.

2C•2 Zetec engine in-car repair procedures
1595Ford Fiesta Remake
1 General information
How to use this Chapter
This Part of Chapter 2 is devoted to repair
procedures possible while the engine is still
installed in the vehicle, and includes only the
Specifications relevant to those procedures.
Similar information concerning the 1.3 litre
HCS engines, and the 1.4 and 1.6 litre CVH
and PTE engines, will be found in Parts A
and B of this Chapter respectively. Since these procedures are based on the
assumption that the engine is installed in the
vehicle, if the engine has been removed from
the vehicle and mounted on a stand, some
of the preliminary dismantling steps outlined
will not apply.
Information concerning engine/transmission
removal and refitting, and engine overhaul, can
be found in Part D of this Chapter, which also
includes the Specifications relevant to those
procedures.
Engine description
The Zetec engine, (formerly Zeta), is of
sixteen-valve, double overhead camshaft (DOHC), four-cylinder, in-line type, mounted
transversely at the front of the vehicle, with
the transmission on its left-hand end.
Apart from the plastic timing belt covers
and the cast-iron cylinder block/crankcase, all
major engine castings are of aluminium alloy. The crankshaft runs in five main bearings,
the centre main bearing’s upper half
incorporating thrustwashers to control
crankshaft endfloat. The connecting rods
rotate on horizontally-split bearing shells at
their big-ends. The pistons are attached to the
connecting rods by gudgeon pins which are
an interference fit in the connecting rod small-
end eyes. The aluminium alloy pistons are

2D•6 Engine removal and overhaul procedures
1595Ford Fiesta Remake
1 General information
Included in this Part of Chapter 2 are details
of removing the engine/transmission from the
car and general overhaul procedures for the
cylinder head, cylinder block/crankcase and
all other engine internal components.
The information given ranges from advice
concerning preparation for an overhaul and
the purchase of replacement parts, to detailed
step-by-step procedures covering removal,
inspection, renovation and refitting of engine
internal components.
After Section 6, all instructions are based
on the assumption that the engine has been
removed from the car. For information
concerning in-car engine repair, as well as the
removal and refitting of those external
components necessary for full overhaul, refer
to Part A, B or C of this Chapter (as
applicable) and to Section 6. Ignore any
preliminary dismantling operations described
in Part A, B or C that are no longer relevant
once the engine has been removed from the
car.
2 Engine/transmission removal - preparation and
precautions
If you have decided that an engine must be
removed for overhaul or major repair work,
several preliminary steps should be taken.
Locating a suitable place to work is
extremely important. Adequate work space,
along with storage space for the car, will be
needed. If a workshop or garage is not
available, at the very least, a flat, level, clean
work surface is required. If possible, clear some shelving close to the
work area and use it to store the engine
components and ancillaries as they are
removed and dismantled. In this manner the
components stand a better chance of staying
clean and undamaged during the overhaul.
Laying out components in groups together
with their fixing bolts, screws etc will save
time and avoid confusion when the engine is
refitted. Clean the engine compartment and
engine/transmission before beginning the
removal procedure; this will help visibility and
help to keep tools clean. On three of the engines covered in this
manual (CVH, PTE, and Zetec), the unit can
only be withdrawn by removing it complete
with the transmission; the vehicle’s body must
be raised and supported securely, sufficiently
high that the engine/transmission can be
unbolted as a single unit and lowered to the
ground; the engine/transmission unit can then
be withdrawn from under the vehicle and
separated. On all engines, an engine hoist or
A- frame will be necessary. Make sure the
equipment is rated in excess of the combined
weight of the engine and transmission. The help of an assistant should be
available; there are certain instances when
one person cannot safely perform all of the
operations required to remove the engine
from the vehicle. Safety is of primary
importance, considering the potential hazards
involved in this kind of operation. A second
person should always be in attendance to
offer help in an emergency. If this is the first
time you have removed an engine, advice and
aid from someone more experienced would
also be beneficial. Plan the operation ahead of time. Before
starting work, obtain (or arrange for the hire
of) all of the tools and equipment you will
need. Access to the following items will allow
the task of removing and refitting the
engine/transmission to be completed safely
and with relative ease: an engine hoist - rated
in excess of the combined weight of the
engine/transmission, a heavy-duty trolley
jack, complete sets of spanners and sockets
as described in “ Tools and working facilities ”
at the rear this manual, wooden blocks, and
plenty of rags and cleaning solvent for
mopping up spilled oil, coolant and fuel. A
selection of different sized plastic storage bins
will also prove useful for keeping dismantled
components grouped together. If any of the
equipment must be hired, make sure that you
arrange for it in advance, and perform all of
the operations possible without it beforehand;
this may save you time and money. Plan on the vehicle being out of use for
quite a while, especially if you intend to carry
out an engine overhaul. Read through the
whole of this Section and work out a strategy based on your own experience and the tools,
time and workspace available to you. Some of
the overhaul processes may have to be
carried out by a Ford dealer or an engineering
works - these establishments often have busy
schedules, so it would be prudent to consult
them before removing or dismantling the
engine, to get an idea of the amount of time
required to carry out the work.
When removing the engine from the vehicle,
be methodical about the disconnection of
external components. Labelling cables and
hoses as they removed will greatly assist the
refitting process.
Always be extremely careful when lifting the
engine/transmission assembly from the
engine bay. Serious injury can result from
careless actions. If help is required, it is better
to wait until it is available rather than risk
personal injury and/or damage to components
by continuing alone. By planning ahead and
taking your time, a job of this nature, although
major, can be accomplished successfully and
without incident.

Warning: Petrol is extremely
flammable, so take extra
precautions when disconnecting
any part of the fuel system.
Don’t smoke, or allow naked flames or bare
light bulbs, in or near the work area, and
don’t work in a garage where a natural-gas
appliance (such as a clothes dryer or water
heater) is installed. If you spill petrol on
your skin, rinse it off immediately. Have a
fire extinguisher rated for petrol fires
handy, and know how to use it.
Note: Read through the entire Section, as well
as reading the advice in the preceding
Section, before beginning this procedure. The
engine is removed separately from the
transmission and is lifted upwards and out of
the engine compartment.
Removal
1 On fuel injection engines, refer to Chap-
ter 4B and depressurise the fuel system.
2 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).

transmission flange attachment bolts (see
illustration) .
19 Check that the appropriate underside
attachments are disconnected and out of the
way, then lower the vehicle to the ground.
20 Unbolt and remove the heat shield from
the exhaust manifold.
21 Attach a suitable hoist to the engine. It is
possible to fabricate lifting eyes to connect
the hoist to the engine, but make sure that
they are strong enough, and connect them to
the inlet and exhaust manifold at diagonally-
opposite ends of the engine.
22 With the hoist securely connected, take
the weight of the engine. Unscrew and
remove the right-hand engine mounting side
bolt from under the right-hand wheel arch.
Unscrew and remove the mounting retaining
nut and washer from the suspension strut cup
retaining plate, and the three bolts securing
the mounting unit to the cylinder block.
23 Locate a jack under the transmission, and
raise it to take the weight of the transmission.
24 Unscrew and remove the remaining
engine-to-transmission retaining bolts on the
upper flange.
25 Check around the engine to ensure that all
of the relevant fixings and attachments are
disconnected and out of the way for the
removal.
26 Enlist the aid of an assistant, then move
the engine sideways and away from the
transmission, whilst simultaneously raising
the transmission. When the engine is
separated from the transmission, carefully
guide it up and out of the engine
compartment. Do not allow the weight of the
engine to hang on the transmission input shaft
at any point during the removal (or refitting) of
the engine. When the engine sump is clear
of the vehicle, swing the power unit out of the
way, and lower it onto a trolley (if available).
Unless a mobile hoist is being used, it will be
necessary to move the vehicle rearwards and
out of the way in order to allow the engine to
be lowered for removal. In this instance,
ensure that the weight of the transmission is
well supported as the vehicle is moved.
27 While the engine is removed, check the
mountings; renew them if they are worn or
damaged. Similarly, check the condition of all
coolant and vacuum hoses and pipes (see Chapter 1); components that are normally
hidden can now be checked properly, and
should be renewed if there is any doubt at all
about their condition. Also, take the
opportunity to overhaul the clutch
components (see Chapter 6). It is regarded by
many as good working practice to renew the
clutch assembly as a matter of course,
whenever major engine overhaul work is
carried out. Check also the condition of all
components disturbed on removal, and renew
any that are damaged or worn.
Refitting
28
Refitting is in general, a reversal of the
removal procedure, but the following special
points should be noted.
29 Before coupling the engine to the
transmission, apply a thin smear of high-
melting-point grease onto the transmission
input shaft splines. If the clutch has been
removed, ensure that the clutch disc is
centralised, and disconnect the clutch cable
from the release lever on the transmission
casing.
30 Tighten all fixings to their recommended
torque wrench settings.
31 Check that the mating faces are clean,
and fit a new exhaust downpipe-to-manifold
gasket and self-locking nuts when
reconnecting this joint.
32 Ensure that all wiring connections are
correctly and securely made.
33 Remove the plugs from the fuel lines
before reconnecting them correctly and
securely.
34 Reconnect and adjust the accelerator and
choke cables as described in the relevant Part
of Chapter 4. The refitting details for the air
cleaner components are also given in that
Chapter.
35 Renew any coolant hoses (and/or
retaining clips) that are not in good condition.
36 Refer to Chapter 6 for details on
reconnecting the clutch cable.
37 When the engine is fully refitted, check
that the various hoses are connected, and
then top-up the engine oil and coolant levels
as described in Chapter 1 and “Weekly
Checks”.
38 When engine refitting is completed, refer to
Section 19 for the engine start-up procedures.

3 Referring to Chapter 1 for details, drain the
coolant and the engine oil. Refit the drain plug
to the sump on completion.
4 Refer to Chapter 11 for details, and remove
the bonnet.
5 Remove the air cleaner assembly and air
inlet components as described in the relevant
Part of Chapter 4.
6 Release the retaining clips and detach the
coolant top hose, the heater hose and the
radiator overflow hose from the thermostat
housing. Disconnect the coolant hose from
the inlet manifold, and the bottom hose from
the water pump and/or the radiator (see
illustrations) . On 1.4 litre CFi fuel injection
models, also disconnect the coolant hose
from the injection unit. On EFi and SEFi fuel
injection models, detach the heater hose
Y-connector. Allow for coolant spillage as the
hoses are detached. On turbocharged
engines, disconnect the coolant return hose
from the turbocharger connecting pipe.

30 Unscrew the retaining nut and withdraw
the Torx-type clamp bolt securing the lower
suspension arm to the spindle carrier on each
side.
31 Refer to Chapter 10 for details, and
detach the right-hand and left-hand track rod
end balljoints from the spindle carriers.
32 On vehicles fitted with the anti-lock
braking system, refer to Chapter 9 and release
the right-hand modulator from its mounting
bracket without disconnecting the rigid brake
pipes or return hose. Tie the modulator
securely to the bulkhead. Additionally, undo
the three bolts securing the modulator
bracket.
33 Insert a suitable lever between the right-
hand driveshaft inner joint and the
transmission housing, and prise free the
driveshaft from the transmission; be prepared
for oil spillage from the transmission case
through the vacated driveshaft aperture. As it
is being prised free, simultaneously pull the
roadwheel outwards on that side, to enable
the driveshaft inboard end to separate
from the transmission. Once it is free,
suspend and support the driveshaft from the
steering gear, to prevent unnecessary strain
being placed on the driveshaft joints.
34 Insert a suitable plastic plug (or if
available, an old driveshaft joint), into the
transmission driveshaft aperture, to
immobilise the gears of the differential unit.
35 Proceed as described above in
paragraphs 33 and 34, and disconnect the
left-hand driveshaft from the transmission.
36 Connect a suitable lift hoist and sling to
the engine, connecting to the lifting eyes. When securely connected, take the weight of
the engine/transmission unit so that the
tension is relieved from the mountings.
37
Undo the retaining bolts and nuts and
detach the right-hand engine mounting from
the vehicle body.
38 Undo the four bolts securing the
transmission bearer to the underside of the
vehicle body. The transmission bearer is
removed with the engine/transmission
assembly.
39 Unscrew the three retaining bolts, and
remove the auxiliary drivebelt cover from
under the crankshaft pulley.
40 The engine/transmission unit should now
be ready for removal from the vehicle. Check
that all of the associated connections and
fittings are disconnected from the engine and
transmission, and positioned out of the way.
41 Enlist the aid of an assistant to help
steady and guide the power unit down
through the engine compartment as it is
removed. If available, position a suitable
engine trolley or crawler board under the
engine/transmission so that when lowered,
the power unit can be withdrawn from the
front end of the vehicle, and then moved to
the area where it is to be cleaned and
dismantled. On automatic transmission
models, particular care must be taken not to
damage the transmission fluid pan (sump)
during the removal and subsequent refitting
processes.
42 Carefully lower the engine and
transmission unit, ensuring that no fittings
become snagged. Detach the hoist and
remove the power unit from under the vehicle.
43 Referring to the relevant Part of Chapter 7,
separate the transmission from the engine.
44 While the engine/transmission is removed,
check the mountings; renew them if they are
worn or damaged. Similarly, check the
condition of all coolant and vacuum hoses
and pipes (see Chapter 1). Components that
are normally hidden can now be checked
properly, and should be renewed if there is
any doubt at all about their condition. Where
the vehicle is fitted with manual transmission,
take the opportunity to inspect the clutch
components (see Chapter 6). It is regarded by
many as good working practice to renew the
clutch assembly as a matter of course,
whenever major engine overhaul work is
carried out. Check also the condition of all
components (such as the transmission oil
seals) disturbed on removal, and renew any
that are damaged or worn.
Refitting
45 Refitting is a reversal of removal, however
note the following additional points:
a) Refer to the applicable Chapters and Sections as for removal.
b) Fit new spring clips to the grooves in the
inboard end of the right- and left-hand
driveshaft joints. Lubricate the splines
with transmission oil prior to fitting. c) Renew the exhaust flange gasket when
reconnecting the exhaust. Ensure that all
wires are routed clear of the exhaust
system and, on catalytic converter
models, ensure that the heat shields are
securely and correctly fitted.
d) Ensure that all earth lead connections are
clean and securely made.
e) Tighten all nuts and bolts to the specified torque.
f) Fit a new oil filter, and refill the engine and transmission with oil, with reference to
Chapter 1.
g) Refill the cooling system with reference to Chapter 1.
h) Refit the alternator and starter motor with reference to Chapter 5A.
i) Where applicable, refit the power steering pump with reference to Chapter 10.
46 When engine and transmission refitting is
complete, refer to the procedures described
in Section 19 before restarting the engine.

Warning: Petrol is extremely
flammable, so take extra
precautions when disconnecting
any part of the fuel system.
Don’t smoke, or allow naked flames or
bare light bulbs, in or near the work area,
and don’t work in a garage where a
natural-gas appliance (such as a clothes
dryer or water heater) is installed. If you
spill petrol on your skin, rinse it off
immediately. Have a fire extinguisher rated
for petrol fires handy, and know how to
use it.
Note: Read through the entire Section, as well
as reading the advice in Section 2, before
beginning this procedure. The engine and
transmission are removed as a unit, lowered to
the ground and removed from underneath,
then separated outside the vehicle.
Removal
1 Park the vehicle on firm, level ground, apply
the handbrake firmly, and slacken the nuts
securing both front roadwheels.
2 Depressurise the fuel system as described
in Chapter 4D.
3 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
4 Place protective covers on the wings, then
remove the bonnet (see Chapter 11).
5 Drain the cooling system and the engine oil
(see Chapter 1).
6 Remove the air inlet components and the
complete air cleaner assembly as described in
Chapter 4D.
7 Equalise the pressure in the fuel tank by
removing the filler cap, then release the fuel
feed and return quick-release couplings, and
pull the hoses off the fuel pipes. Plug or cap
all open fittings.

HCS engines
4Check that the main bearing caps have
marks to indicate their respective fitted
positions in the block. They also have arrow
marks pointing towards the timing chain cover
end of the engine to indicate correct
orientation (see illustration) .
5 Unscrew the retaining bolts, and remove
the main bearing caps. If the caps are
reluctant to separate from the block face,
lightly tap them free using a plastic- or
copper-faced hammer. If the bearing shells
are likely to be used again, keep them with
their bearing caps for safekeeping. However,
unless the engine is known to be of low
mileage, it is recommended that they be
renewed.
6 Lift the crankshaft out from the crankcase,
then extract the upper bearing shells and side
thrustwashers. Keep them with their
respective caps for correct repositioning if
they are to be used again.
7 Remove the crankshaft oil seals from the
timing cover and the rear oil seal housing.
CVH and PTE engines
8 Check that each main bearing cap is
numerically marked for position. Each cap
should also have an arrow marking to indicate
its direction of fitting (arrow points to the
timing belt end).
9 Unscrew the retaining bolts, and remove
the main bearing caps. As they are removed,
keep each bearing shell with its cap (in case
they are to used again). Note that the bearing
shells in the main bearing caps are plain (no
groove). It is recommended that the shells be
renewed, unless the engine is known to be of
low mileage.
10 Lift out the crankshaft from the crankcase.
11 Remove each bearing shell in turn from
the crankcase, and keep them in order of
fitting. Note that the upper shell halves are
grooved. Also remove the semi-circular
thrustwasher from each side of the central
main bearing web, and keep them in their
order of fitting.
Zetec engines
12 Check the main bearing caps, to see if they are marked to indicate their locations
(see illustration)
. They should be numbered
consecutively from the timing belt end of the
engine - if not, mark them with number-
stamping dies or a centre-punch. The caps
will also have an embossed arrow pointing to
the timing belt end of the engine. Noting the
different fasteners (for the oil baffle nuts) used
on caps 2 and 4, slacken the cap bolts a
quarter-turn at a time each, starting with the
left- and right-hand end caps and working
toward the centre, until they can be removed
by hand.
13 Gently tap the caps with a soft-faced
hammer, then separate them from the cylinder
block/crankcase. If necessary, use the bolts
as levers to remove the caps. Try not to drop
the bearing shells if they come out with the
caps.
14 Carefully lift the crankshaft out of the
engine.
15 Remove each bearing shell in turn from
the cylinder block/crankcase, and keep them
in order of fitting.
Inspection
16 Clean the crankshaft, and dry it with
compressed air if available.
Warning: Wear eye protection
when using compressed air! Be
sure to clean the oil holes with a
pipe cleaner or similar probe.
17 Check the main and crankpin (big-end)
bearing journals for uneven wear, scoring,
pitting and cracking.
18 Big-end bearing wear is accompanied by
distinct metallic knocking when the engine is
running (particularly noticeable when the
engine is pulling from low speed) and some
loss of oil pressure.
19 Main bearing wear is accompanied by
severe engine vibration and rumble - getting
progressively worse as engine speed
increases - and again by loss of oil pressure.
20 Check the bearing journal for roughness
by running a finger lightly over the bearing
surface. Any roughness (which will be
accompanied by obvious bearing wear)
indicates that the crankshaft requires
regrinding (where possible) or renewal. 21
Remove all burrs from the crankshaft oil
holes with a stone, file or scraper.
22 Using a micrometer, measure the
diameter of the main bearing and crankpin
(big-end) journals, and compare the results
with the Specifications at the beginning of this
Chapter (see illustration) .
23 By measuring the diameter at a number of
points around each journal’s circumference,
you will be able to determine whether or not
the journal is out-of-round. Take the
measurement at each end of the journal, near
the webs, to determine if the journal is
tapered.
24 If the crankshaft journals are damaged,
tapered, out-of-round, or worn beyond the
limits specified in this Chapter, the crankshaft
must be taken to an engine overhaul
specialist, who will regrind it, and who can
supply the necessary undersize bearing
shells.
25 Check the oil seal journals at each end of
the crankshaft for wear and damage. If either
seal has worn an excessive groove in its
journal, consult an engine overhaul specialist,
who will be able to advise whether a repair is
possible, or whether a new crankshaft is
necessary.
13 Cylinder block/crankcase -
cleaning and inspection
2
Cleaning
1 Prior to cleaning, remove all external
components and senders. On HCS engines,
make sure that the camshaft and tappets are
removed before carrying out thorough
cleaning of the block. On the CVH and PTE
engines, remove the engine ventilation cap
from the recess in the rear corner of the
cylinder block and if still fitted, undo the
retaining screw and withdraw the engine
speed sensor from the bellhousing face. On
Zetec engines, unbolt the piston-cooling oil
jets or blanking plugs (as applicable); note
that Ford state that the piston-cooling oil jets
(where fitted) must be renewed whenever the

engine is dismantled for full overhaul (see
illustrations) .
2 Remove all oil gallery plugs (where fitted).
The plugs are usually very tight - they may
have to be drilled out, and the holes re-
tapped. Use new plugs when the engine is
reassembled. Drill a small hole in the centre of
each core plug, and pull them out with a car
bodywork dent puller.
Caution: The core plugs (also known as
freeze or soft plugs) may be difficult or
impossible to retrieve if they are driven
into the block coolant passages.
3 If any of the castings are extremely dirty, all
should be steam-cleaned.
4 After the castings are returned from steam-
cleaning, clean all oil holes and oil galleries
one more time. Flush all internal passages
with warm water until the water runs clear,
then dry thoroughly, and apply a light film of
oil to all machined surfaces, to prevent
rusting. If you have access to compressed air,
use it to speed the drying process, and to
blow out all the oil holes and galleries.
Warning: Wear eye protection
when using compressed air!
5 If the castings are not very dirty, you can do
an adequate cleaning job with hot soapy
water (as hot as you can stand!) and a stiff
brush. Take plenty of time, and do a thorough
job. Regardless of the cleaning method used,
be sure to clean all oil holes and galleries very thoroughly, and to dry all components
completely; protect the machined surfaces as
described above, to prevent rusting.
6
All threaded holes must be clean and dry,
to ensure accurate torque readings during
reassembly; now is also a good time to clean
and check the threads of all principal bolts -
however, note that some, such as the cylinder
head and flywheel/driveplate bolts, are to be
renewed as a matter of course whenever they
are disturbed. Run the proper-size tap into
each of the holes, to remove rust, corrosion,
thread sealant or sludge, and to restore
damaged threads (see illustration). If
possible, use compressed air to clear the
holes of debris produced by this operation; a
good alternative is to inject aerosol-applied
water-dispersant lubricant into each hole,
using the long spout usually supplied. Warning: Wear eye protection
when cleaning out these holes
in this way, and be sure to dry
out any excess liquid left in the
holes.
7 When all inspection and repair procedures
are complete (see below) and the block is
ready for reassembly, apply suitable sealant
to the new oil gallery plugs, and insert them
into the holes in the block. Tighten them
securely. After coating the sealing surfaces of
the new core plugs with suitable sealant,
install them in the cylinder block/crankcase.
Make sure they are driven in straight and seated properly, or leakage could result.
Special tools are available for this purpose,
but a large socket with an outside diameter
that will just slip into the core plug, used with
an extension and hammer, will work just as
well.
8
On Zetec engines, refit the blanking plugs
or (new) piston-cooling oil jets (as applicable),
tightening their Torx screws to the torque
wrench setting specified. On all engines, refit
all other external components removed,
referring to the relevant Chapter of this
manual for further details where required.
Refit the main bearing caps, and tighten the
bolts finger-tight.
9 If the engine is not going to be reassembled
right away, cover it with a large plastic bag to
keep it clean; protect the machined surfaces
as described above, to prevent rusting.
Inspection
10 Visually check the castings for cracks and
corrosion. Look for stripped threads in the
threaded holes. If there has been any history
of internal coolant leakage, it may be
worthwhile having an engine overhaul
specialist check the cylinder block/crankcase
for cracks with special equipment. If defects
are found, have them repaired, if possible, or
renew the assembly.
11 Check each cylinder bore for scuffing and
scoring.
12 The cylinder bores must be measured
with all the crankshaft main bearing caps
bolted in place (without the crankshaft and
bearing shells), and tightened to the specified
torque wrench settings. Measure the diameter
of each cylinder at the top (just under the
ridge area), centre and bottom of the cylinder
bore, parallel to the crankshaft axis. Next,
measure each cylinder’s diameter at the same
three locations across the crankshaft axis
(see illustration) . Note the measurements
obtained.
13 Measure the piston diameter at right-
angles to the gudgeon pin axis, just above the
bottom of the skirt; again, note the results
(see illustration) .
14 If it is wished to obtain the piston-to-bore
clearance, measure the bore and piston skirt
as described above, and subtract the skirt

Plastigauge to the scale printed on the
Plastigauge envelope, to obtain the running
clearance (see illustration 17.15) . Compare it
to the Specifications, to make sure the
clearance is correct.
14 If the clearance is not as specified, seek
the advice of a Ford dealer or similar engine
reconditioning specialist - if the crankshaft
journals are in good condition it may be
possible simply to renew the shells to achieve
the correct clearance. If this is not possible,
the crankshaft must be reground by a
specialist, who can also supply the necessary
undersized shells. First though, make sure
that no dirt or oil was trapped between the
bearing shells and the connecting rod or cap
when the clearance was measured. Also,
recheck the crankpin diameter. If the
Plastigauge was wider at one end than the
other, the crankpin journal may be tapered.
15 Carefully scrape all traces of the
Plastigauge material off the journal and the
bearing surface. Be very careful not to scratch
the bearing - use your fingernail or the edge of a credit card.
Final piston/connecting rod
refitting
16 Make sure the bearing surfaces are
perfectly clean, then apply a uniform layer of
clean molybdenum disulphide-based grease,
engine assembly lubricant, or clean engine oil,
to both of them. You’ll have to push the piston
into the cylinder to expose the bearing surface
of the shell in the connecting rod.
17 Slide the connecting rod back into place
on the crankpin (big-end) journal, refit the big-
end bearing cap, and then tighten the bolts as
described above.
18 Repeat the entire procedure for the
remaining piston/connecting rod assemblies.
19 The important points to remember are:
a) Keep the backs of the bearing shells and the recesses of the connecting rods and
caps perfectly clean when assembling
them.
b) Make sure you have the correct
piston/rod assembly for each cylinder -
use the etched cylinder numbers to
identify the front-facing side of both the
rod and its cap.
c) The arrow on the piston crown must face the timing belt/chain end of the engine.
d) Lubricate the cylinder bores with clean
engine oil.
e) Lubricate the bearing surfaces when refitting the big-end bearing caps after the
running clearance has been checked. 20
After all the piston/connecting rod
assemblies have been properly installed,
rotate the crankshaft a number of times by
hand, to check for any obvious binding.
21 On HCS engines, if the oil pick-up pipe
and strainer was removed, this is a good time
to refit it. First clean the joint area, then coat
the area indicated with the specified activator
(available from Ford dealers) (see
illustration) . Wait for a period of ten minutes,
then smear the shaded area with the specified
adhesive and immediately press the inlet pipe
into position in the crankcase.
19 Engine - initial start-up after
overhaul
1
1 With the engine refitted in the vehicle,
double-check the engine oil and coolant
levels. Make a final check that everything has
been reconnected, and that there are no tools
or rags left in the engine compartment.
2 With the spark plugs removed and the
ignition system disabled by unplugging the
ignition coil’s electrical connector, remove the
fuel pump fuse (fuel injection engines) to
disconnect the fuel pump (see Chapter 12).
Turn the engine on the starter until the oil
pressure warning light goes out.
3 Refit the spark plugs, and connect all the
spark plug (HT) leads (Chapter 1). Reconnect
the ignition coil. On fuel injection engines, refit the fuel pump fuse, switch on the ignition and
listen for the fuel pump; it will run for a little
longer than usual, due to the lack of pressure
in the system.
4
Start the engine, noting that this also may
take a little longer than usual, due to the fuel
system components being empty.
5 While the engine is idling, check for fuel,
coolant and oil leaks. Don’t be alarmed if
there are some odd smells and smoke from
parts getting hot and burning off oil deposits.
If the hydraulic tappets (where applicable)
have been disturbed, some valve gear noise
may be heard at first; this should disappear as
the oil circulates fully around the engine, and
normal pressure is restored in the tappets.
6 Keep the engine idling until hot water is felt
circulating through the top hose, check that it
idles reasonably smoothly and at the usual
speed, then switch it off.
7 After a few minutes, recheck the oil and
coolant levels, and top-up as necessary
(Chapter 1).
8 If they were tightened as described, there is
no need to re-tighten the cylinder head bolts
once the engine has first run after reassembly
- in fact, Ford state that the bolts must notbe
re-tightened.
9 If new components such as pistons, rings
or crankshaft bearings have been fitted, the
engine must be run-in for the first 500 miles
(800 km). Do not operate the engine at full-
throttle, or allow it to labour in any gear during
this period. It is recommended that the oil and
filter be changed at the end of this period.
