1•6Maintenance Procedures
This Chapter is designed to help the home
mechanic maintain his/her vehicle for safety,
economy, long life and peak performance.
The Chapter contains a master maintenance
schedule, followed by Sections dealing
specifically with each task in the schedule.
Visual checks, adjustments, component
renewal and other helpful items are included.
Refer to the accompanying illustrations of the
engine compartment and the underside of the
vehicle for the locations of the various
components.
Servicing your vehicle in accordance with
the mileage/time maintenance schedule and
the following Sections will provide a planned
maintenance programme, which should result
in a long and reliable service life. This is a
comprehensive plan, so maintaining some
items but not others at the specified service
intervals, will not produce the same results.
As you service your vehicle, you will
discover that many of the procedures can -
and should - be grouped together, because of
the particular procedure being performed, or
because of the close proximity of two
otherwise-unrelated components to one
another. For example, if the vehicle is raised
for any reason, the exhaust can be inspected
at the same time as the suspension and
steering components.
The first step in this maintenanceprogramme is to prepare yourself before the
actual work begins. Read through all the
Sections relevant to the work to be carried out,
then make a list and gather together all the
parts and tools required. If a problem is
encountered, seek advice from a parts
specialist, or a dealer service department.
If, from the time the vehicle is new, the
routine maintenance schedule is followed
closely, and frequent checks are made of fluid
levels and high-wear items, as suggested
throughout this manual, the engine will be kept
in relatively good running condition, and the
need for additional work will be minimised.
It is possible that there will be times when
the engine is running poorly due to the lack of
regular maintenance. This is even more likely if
a used vehicle, which has not received regular
and frequent maintenance checks, is
purchased. In such cases, additional work
may need to be carried out, outside of the
regular maintenance intervals.
If engine wear is suspected, a compression
test will provide valuable information regarding
the overall performance of the main internal
components. Such a test can be used as a
basis to decide on the extent of the work to be
carried out. If, for example, a compression test
indicates serious internal engine wear,
conventional maintenance as described in this
Chapter will not greatly improve theperformance of the engine, and may prove a
waste of time and money, unless extensive
overhaul work is carried out first.
The following series of operations are those
most often required to improve the
performance of a generally poor-running
engine:
Primary operations
a)Clean, inspect and test the battery
(Section 6)
b)Check all the engine-related fluids
(Section 3).
c)Check the condition and tension of the
auxiliary drivebelt (Section 21).
d)Renew the spark plugs (Section 20).
e)Inspect the distributor cap, rotor arm and
HT leads - as applicable (Chapter 5).
f)Check the condition of the air cleaner filter
element, and renew if necessary (Section 38).
g)Renew the fuel filter (Section 41).
h)Check the condition of all hoses, and
check for fluid leaks (Section 10).
i)Check the idle speed and mixture settings
- as applicable (Chapter 4).
If the above operations do not prove fully
effective, carry out the following secondary
operations:
Secondary operations
a)Check the charging system (Chapter 5).
b)Check the ignition system (Chapter 5).
c)Check the fuel system (Chapter 4).
d)Renew the distributor cap and rotor arm -
as applicable (Chapter 5).
f)Renew the ignition HT leads - as
applicable (Chapter 5).
2Intensive maintenance
1Introduction
Engine oil
1Check the oil level as follows.
2With the vehicle parked on level ground,
and with the engine having been stopped for a
few minutes, open and prop the bonnet.
Withdraw the dipstick, wipe it on a clean ragand re-insert it fully. Withdraw it again and
read the oil level relative to the marks on the
end of the stick (see illustration).
3The oil level should be in between the MAX
and MIN marks on the dipstick. If it is at or
below the MIN mark, top-up (via the oil filler
cap) without delay. The quantity of oil required
to raise the lever from MIN to MAX on the
dipstick is approximately 1 litre. Do not overfill
(see illustration).
4The rate of oil consumption depends onleaks and on the quantity of oil burnt. External
leakage should be obvious. Oil which is burnt
may enter the combustion chambers through
the valve guides or past the piston rings;
excessive blow-by past the rings can also
force oil out via the crankcase ventilation
system. Driving conditions also affect oil
consumption.
5Always use the correct grade and type of oil
as shown in “Lubricants and fluids”.
Coolant
6Check the coolant level as follows.
7Open and prop the bonnet. Observe the
level of coolant through the translucent walls
of the expansion tank (on the right-hand side
of the engine bay). The level should be up to
the MAX mark when the engine is cold, and
may be somewhat above the mark when hot.
8If topping-up is necessary, wait for the
system to cool down if it is hot. Place a thick
rag over the expansion tank cap and slacken it
3Fluid level checks
3.2 Dipstick markings3.3 Topping up the engine oil
Warning: DO NOT remove the
expansion tank pressure cap
when the engine is hot, as there
is a great risk of scalding.
Weekly checks

DOHC engines
12On this engine, the coolant/alternator
drivebelt also drives the power steering pump
and (where applicable) the air conditioning
compressor. The drivebelt tension is set by an
automatic tensioner assembly.
13The condition of the drivebelt should be
checked as described above.
14An idea of the amount of wear which has
taken place on the belt can be gained from the
position of indicator mark (A) on the mounting
bracket in relation to the block (B) on the
tensioner arm (see illustration).When the belt
is new the mark should be aligned with the top
of the tensioner block. As the belt wears, the
tensioner arm moves and the block on the arm
will move slowly up in relation to the mark on
the bracket. When the mark aligns with the
bottom of the tensioner arm block the belt can
be regarded as worn and should be replaced
(see illustration).
15To renew the belt, turn the automatic
tensioner arm clockwise, using a 17 mm
socket and a wrench on the boss in the centre
of the pulley, and slide the belt from the
pulleys, then slowly release the tensioner.
16To fit a new belt, rotate the tensioner
clockwise as during removal, then slide the
belt over the pulleys. With the belt correctly
located, slowly release the tensioner; the
tensioner will automatically set the correct
drivebelt tension.
Caution:Before carrying out any work on the
vehicle battery, read through the precautions
given in “Safety first!” at the beginning of this
manual.
1The battery fitted as original equipment is
“maintenance-free”, and requires no
maintenance apart from having the case kept
clean, and the terminals clean and tight.
2To clean the battery terminals disconnect
them, after having first removed the cover
(later models) -negative earth first. Use a wire
brush or abrasive paper to clean the terminals.
Bad corrosion should be treated with a
solution of bicarbonate of soda, applied with
an old toothbrush. Do not let this solution get
inside the battery.3Coat the battery terminals with petroleum
jelly or a proprietary anti-corrosive compound
before reconnecting them. Reconnect and
tighten the positive (live) lead first, followed by
the negative (earth) lead. Do not overtighten.
4Keep the top of the battery clean and dry.
Periodically inspect the battery tray for
corrosion, and make good as necessary.
5Further information on the battery, charging
and jump-starting can be found in Chapter 5,
and in the preliminary Sections of this manual.
SOHC engines
1Valve clearances are checked with the
engine cold.
2On carburettor models, remove the air cleaner.
3On fuel-injection models, remove the
bracing strap which connects the inlet
manifold to the right-hand side of the engine.
4On all models, identify the HT leads and
disconnect them from the spark plugs. Unclip
the leads from the rocker cover.
5Although not essential, it will make the
engine easier to turn if the spark plugs are
removed.
6Remove the ten bolts which secure the
rocker cover, noting the location of the
different shapes of reinforcing plates. Remove
the cover and gasket.7One of the cam lobes will be seen to be
pointing upwards. Measure the clearance
between the base of this cam and the cam
follower, finding the thickness of feeler blade
which gives a firm sliding fit(see illustration).
8The desired valve clearances are given in
the Specifications. Note that the clearances
for inlet and exhaust valves are different.
Numbering from the front (sprocket) end of the
camshaft, the exhaust valves are 1, 3, 5 and 7,
and the inlet valves 2, 4, 6 and 8.
9If adjustment is necessary, slacken the ball-
pin locknut and screw the ball-pin up or down
until the clearance is correct. Hold the ball-pin
stationary and tighten the locknut(see
illustration).Recheck the clearance after
tightening the locknut in case the ball-pin has
moved.
10Turn the engine to bring another cam lobe
to the vertical position and repeat the above
procedure. Carry on until all eight valves have
been checked.
11Access to some of the ball-pins is made
difficult by the carburettor or fuel-injection inlet
manifold. To avoid having to remove the
offending components, double cranked
spanners or cutaway socket spanners can be
used (see illustration).
12When adjustment is complete, refit the
rocker cover using a new gasket. Make sure
that the dovetail sections of the gasket fit
together correctly.
13Fit the rocker cover bolts and reinforcing
plates. Tighten the bolts as described in
Chapter 2A Section 44, paragraph 11.

14Refit the other disturbed components. 
15Run the engine and check that there are
no oil leaks from the rocker cover.
2.8 litre engine
16If the engine is in the vehicle, carry out the
preliminary steps:
a)Disconnect the battery negative lead
b)Remove the throttle mechanism cover, air
cleaner cover, airflow meters and inlet
trunking
c)Remove the HT leads from the spark plugs
and unclip them from the rocker cover
d)Unbolt and remove the rocker covers
17Although not essential, it will be easier to
turn the engine if the spark plugs are removed.
18Valve clearances must be adjusted with
the engine cold (less than 40°C/104°F).
19Turn the engine, using a spanner on the
crankshaft pulley bolt, until the crankshaft
pulley timing mark is aligned with the TDC
(zero) pointer on the timing cover and the
valves of No 5 cylinder are overlapping, ie the
exhaust valve is closing and the inlet valve is
opening. (No 5 cylinder is the middle one on
the left-hand bank - left being the vehicle’s
left, not necessarily to operator’s.) (see
illustration).
20When the valves of No 5 cylinder are in
this position, check the valve clearances of
No1 cylinder by inserting a feeler blade of the
specified thickness between the rocker arm
and the valve stem. Adjust the clearance, if
necessary, by turning the rocker arm adjustingscrew until the specified clearance is obtained
(see illustration).Inlet and exhaust valve are
different.
21If the engine is now rotated one-third of a
turn clockwise at the crankshaft, the valves of
No 3 cylinder will be overlapping and the
valves of No4 cylinder can be checked and
adjusted.
22Proceed to adjust the clearances
according to the firing order as follows. The
cylinders are numbered (see illustration)and
the valves are listed in their correct order,
working from the front of the engine:
Valves overlappingValves to adjust
No 5 cylinderNo 1 cylinder (in, ex)
No 3 cylinderNo 4 cylinder (in, ex)
No 6 cylinderNo 2 cylinder (in, ex)
No 1 cylinderNo 5 cylinder (ex, in)
No 4 cylinderNo 3 cylinder (ex, in)
No 2 cylinderNo 6 cylinder (ex, in)
23Refit the rocker covers, using new gaskets
if necessary. Tighten the rocker cover bolts to
the specified torque.
24If the engine is in the vehicle, refit the other
displaced components.
2.4 & 2.9 litre engines
25The operation for these engines is
essentially as described for the 2.8 litre
engine, noting that the valve arrangement is
changed (see illustrations).
Using a spanner of the appropriate size,
check each manifold securing nut in turn
whilst referring to the appropriate Sections in
Chapter 2C for tightening sequences and
torque loading figures.
Remove the radiator grille and clean any
leaves, insects etc. from the condenser coil
and fins. Be very careful not to damage the
condenser fins: use a soft brush, or a
compressed air jet, along (not across) the fins
(see illustration).

The cylinder head is of crossflow design
with the inlet manifold mounted on the left-
hand side and the exhaust manifold mounted
on the right-hand side.
Lubrication is by means of a bi-rotor pump
which draws oil through a strainer located
inside the sump, and forces it through a full-
flow filter into the engine oil galleries where it
is distributed to the crankshaft, camshaft and
auxiliary shaft. The big-end bearings are
supplied with oil via internal drillings in the
crankshaft.The undersides of the pistons are
supplied with oil from drillings in the big-ends.
The distributor shaft is intermittently supplied
with oil from the drilled auxiliary shaft. The
camshaft and cam followers are supplied with
oil via a drilled spray tube from the centre
camshaft bearing.
A semi-closed crankcase ventilation system
is employed whereby piston blow-by gases
are drawn into the inlet manifold via an oil
separator and on carburettor models a control
valve.
The following operations can be carried out
without removing the engine, although the
work may be easier and quicker with the
engine removed:
a)Removal and refitting of the cylinder head
b)Removal and refitting of the camshaft
(after removing the cylinder head)
c)Removal and refitting of the timing belt
and sprockets
d)Removal and refitting of the sump and oil
pump
e)Removal and refitting of the pistons,
connecting rods and big-end bearings
f)Renewal of the engine mountings
g)Renewal of the crankshaft oil seals
h)Removal and refitting of the auxiliary shaft
j)Removal and refitting of the flywheel
The engine must be removed from the
vehicle for the following operations:
a)Renewal of the crankshaft main bearings
b)Removal and refitting of the crankshaft
The engine may be lifted out either on its
own or together with the gearbox. Unless work
is also necessary on the gearbox it is
recommended that the engine is removed on
its own. Where automatic transmission is
fitted, the engine should be removed on its
own owing to the additional weight. If the
engine and gearbox are removed together,
they will have to be tilted at a very steep angle;
make sure that the range of the lifting tackle is
adequate.1Disconnect the battery negative lead.
2Remove the bonnet.
3On carburettor models, remove the air
cleaner. On fuel-injection models, remove the
air cleaner cover, vane airflow meter and air
inlet trunking.
4If a splash guard is fitted, remove it.
5Release the securing clips and bolts and
remove the upper half of the fan shroud. On
carburettor models remove the lower half of
the shroud too.
6Drain the cooling system.
7Disconnect the radiator top and bottom
hoses from the thermostat housing and water
pump. Disconnect the top hose spur from the
expansion tank and unclip it.
8Disconnect the heater hoses from the water
pump and from the inlet manifold or automatic
choke housing. Unclip the hoses.
9On models with power steering, remove the
steering pump.
10Disconnect the vacuum pipe(s) from the
inlet manifold, labelling them if there is any
possibility of confusion.
11Disconnect the following wiring, as
applicable:
a)Alternator 
b)Temperature gauge sender 
c)Engine management temperature sensor 
d)Distributor 
e)Oil pressure switch 
f)Automatic choke and thermo-switch 
g)Carburettor stepper motor 
h)Fuel-injection system sub-harness 
j)Inlet manifold heater
12Disconnect the HT lead from the coil. 
13If an oil level sensor is fitted, remove it
(see illustration).
14Unbolt the throttle cable bracket,
disconnect the inner cable and move the cable
and bracket aside. Also disconnect the
downshift cable on automatic transmission
models.
15On carburettor models, disconnect the
fuel lines from the fuel pump (mechanised
type) and from the carburettor. Be prepared
for fuel spillage.
16On fuel-injection models, disconnect the
fuel supply union from the injector rail, and the
fuel return pipe from the fuel pressureregulator. Be prepared for fuel spillage, and
for some spray if the supply side is still
under pressure.
17Unbolt the exhaust downpipe from the
manifold.
18On models with air conditioning, unbolt
the compressor and move it aside without
straining the flexible hoses.
19Remove the starter motor.
20Although not specified by the
manufacturers, the author advises that either
the radiator or the cooling fan be removed, to
reduce the risk of damage.
21Attach the lifting tackle to the two lifting
eyes on the engine, so that when suspended
the engine will be roughly horizontal. Take the
weight of the engine.
22Remove the single nut on each side which
secures each engine bearer to its mounting.
23Working under the vehicle, remove the
bracing strap which connects the engine and
transmission. Unbolt the adapter plate from
the bottom of the transmission bellhousing.
24On automatic transmission models, unbolt
the torque converter from the driveplate.
25Remove the engine-to-bellhousing bolts.
Note the location of the battery earth strap.
26Support the transmission, preferably with
a trolley jack.
27Check that nothing has been overlooked,
then raise the engine and draw it forwards
clear of the transmission input shaft. Do not
allow the weight of the engine to hang on the
shaft, and do not lift the transmission by it.
28On automatic transmission models, make
sure that the torque converter stays engaged
with the oil pump in the transmission as the
engine is withdrawn,
29Lift the engine out of the engine bay and
take it to the bench.
1Engine removal with automatic transmission
is not recommended.
2Proceed as in the previous Section,
paragraphs 1 to 18.
3Disconnect the wiring from the starter
motor, and release the battery earth cable
from its bellhousing bolt.
4Remove the radiator.
5Remove the propeller shaft.
6Disconnect and unclip the reversing light
switch and speedometer sender unit wiring.
7Disconnect the clutch cable.
8Unbolt the anti-roll bar mounting brackets
and lower the anti-roll bar as far as possible.
9From inside the vehicle remove the gear
lever.
10Drain the engine oil.
11Unhook the exhaust system from its
mounting on the gearbox crossmember. Either
support the system or remove it completely.
12Support the gearbox, preferably with a
trolley jack, then unbolt and remove the
gearbox crossmember. Note the earth strap (if
fitted) under one of the crossmember bolts.
13Attach lifting tackle to the two lifting eyes
on the engine so that when suspended it will
be at an angle of approximately 45°.

14Take the weight of the engine and remove
the two engine bearer-to-mounting nuts.
15Lift the engine/transmission, at the same
time lowering the trolley jack. Draw the unit
forwards and lift it out of the engine bay.
16Temporarily refit the anti-roll bar if the
vehicle is to be moved.
1With the engine and gearbox on the bench,
remove the starter motor.
2Remove the bolt from the engine adapter plate.
3Remove the bracing strap and the
remaining engine-to-bellhousing bolts.
4With the aid of an assistant draw the
gearbox off the engine. Do not allow the weight
of the gearbox to hang on the input shaft.
1It is best to mount the engine on a
dismantling stand, but if this is not available,
stand the engine on a strong bench at a
comfortable working height. Failing this, it will
have to be stripped down on the floor.
2Cleanliness is most important, and if the
engine is dirty, it should be cleaned with
paraffin while keeping it in an upright position.
3Avoid working with the engine on a concrete
floor, as grit can be a real source of trouble.
4As parts are removed, clean them in paraffin.
However, do not immerse parts with internal
oilways in paraffin as it is difficult to remove,
usually requiring a high pressure hose.
5It is advisable to have suitable containers to
hold small items according to their use, as this
will help when reassembling the engine and
also prevent possible losses.
6Always obtain complete sets of gaskets
when the engine is being dismantled, but
retain the old gaskets with a view of using
them as a pattern to make a replacement if a
new one is not available.7When possible, refit nuts, bolts and washers
in their location after being removed, as this
helps protect the threads and will also be
helpful when reassembling the engine.
8Retain unserviceable components in order
to compare them with the new parts supplied.
9A Torx key, size T55, will be needed for
dealing with the cylinder head bolts. A 12-
spline key (to fit bolt size M8) will be needed
for the oil pump bolts. Other Torx and 12-
spline bolts may be encountered; sets of the
keys required to deal with them are available
from most motor accessory shops and tool
factors.
10Another tool which is useful, though by no
means essential, is a valve spring compressor
of the type which hooks under the camshaft
(see illustration). As a Ford tool this bears the
number 21-005-A; proprietary versions may
also be available.
Before dismantling the engine into its main
components, the following ancillary
components can be removed. The actual
items removed, and the sequence of removal,
will depend on the work to be done:
Inlet manifold and associated items
Exhaust manifold
Fuel pump (mechanical type) and pushrod
Alternator
Distributor, HT leads and spark plugs
Fan, water pump and thermostat
Oil pressure switch 
(see illustration)
Temperature gauge senderOil filter and dipstick
Engine bearer arms (see illustration)
Crankcase ventilation components
Clutch
Alternator mounting bracket (see
illustration)
1If the engine is still in the vehicle, carry out
the following preliminary operations:
a)Disconnect the battery negative lead
b)Drain the cooling system
c)Remove the inlet and exhaust manifolds
d)Disconnect the radiator top hose from the
thermostat housing, and the spur from the
expansion tank
e)Disconnect the wiring from the
temperature gauge sender
f)Remove the distributor cap, HT leads and
spark plugs
2Unscrew the bolts and withdraw the timing
cover (see illustration). Note the location of
the cover in the special bolt.
3Using a socket on the crankshaft pulley bolt.
turn the engine clockwise until the TDC (top
dead centre) notch on the pulley is aligned
with the pointer on the crankshaft front oil seal
housing, and the pointer on the camshaft
sprocket is aligned with the indentation on the
cylinder head (see illustrations).Note the
position of the distributor rotor arm, and mark
its contact end in relation to the rim of the
distributor body.

1Remove the camshaft as described in the
previous Section. (If tool 21-005-A is available,
leave the camshaft in place until the valves
have been removed).
2Using a valve spring compressor, compress
each valve spring in turn until the split collets
can be removed. Release the compressor and
remove the cap and spring, keeping them
identified for location (see illustrations).
3Remove each valve from the cylinder head,
but identify them for location (see illustration).
4Prise the valve stem oil seals from the tops
of the valve guides (see illustration).
5If necessary unscrew the cam follower ball-
pins from the cylinder head, keeping them
identified for location.
6If necessary unscrew the bolts and remove
the timing belt tensioner.
7Remove the thermostat and housing.
8Remove the temperature gauge sender unit. 
9Remove the manifold studs if wished by
locking two nuts onto each stud in turn and
unscrewing it.
1If the engine is still in the vehicle, carry out
the following preliminary operations:
a)Disconnect the battery negative lead
b)Remove the radiator and disconnect the
hose from the thermostat housing
c)Remove the accessory drivebelt(s)
2Unscrew the bolts and withdraw the timing
cover. Note the location of the cover in the
special bolt.
3Using a socket on the crankshaft pulley bolt,
turn the engine clockwise until the TDC (top
dead centre) notch on the pulley is alignedwith the pointer on the crankshaft front oil seal
housing, and the pointer on the camshaft
sprocket is aligned with the indentation on the
cylinder head. Note the position of the
distributor rotor arm. Mark the contact end of
the rotor in relation to the rim of the distributor
body.
4Slacken the timing belt tensioner retaining
bolts then pivot the tensioner pulley away from
the belt, to obtain maximum drivebelt free play
(see illustration). Hold the tensioner pulley in
this position and securely retighten the
retaining bolts.
5Mark the running direction of the belt if it is
to be re-used, then slip it off the camshaft
sprocket.
6Slacken the crankshaft pulley bolt. Prevent
the crankshaft from turning by engaging 5thgear (manual gearbox), or by removing the
starter motor and jamming the ring gear teeth.
Alternatively, if the pulley has peripheral bolt
holes, screw in a couple of bolts and use a
lever between them to jam it. Do not allow the
crankshaft to turn very far, or piston/valve
contact may occur.
7Remove the bolt and washer and withdraw
the pulley. If the pulley will not come off easily,
refit the bolt part way and use a puller (see
illustration). A puller will almost certainly be
required on fuel-injection models.
8Remove the guide washer from in front of
the crankshaft sprocket, then remove the
timing belt (see illustration). Do not kink it or
get oil on it if it is to be re-used.
9Remove the crankshaft sprocket using a
puller if necessary (see illustration).

20Remove the water pump/alternator
drivebelt, then unbolt the power steering
pump from the mounting bracket and move it
clear of the engine. Note that there is no need
to disconnect the fluid hoses, but make sure
that the pump is adequately supported to
avoid straining them.
21On models fitted with air conditioning,
unbolt the air conditioning compressor from the
mounting bracket, and move it clear of the
engine (see illustration). Do notdisconnect the
hoses, but make sure that the compressor is
adequately supported to avoid straining them.
22Unscrew and remove the top engine-to-
gearbox bolts which are accessible from the
engine compartment. Note the location of the
bolts, and the positions of the earth strap and
any wiring clips attached to the bolts.
23Unscrew the securing bolt, and
disconnect the earth lead from the rear left-
hand side of the cylinder head.
24Unscrew the nuts securing the engine
mountings to the engine mounting brackets.
25Apply the handbrake, jack up the front of
the vehicle and support it securely on axle
stands (see “Jacking”).

the air conditioning system may
obstruct work being undertaken
on the engine, and it is not always possible
to unbolt and move them aside sufficiently,
within the limits of their flexible pipes. In
such a case, the system should be
discharged by a Ford dealer or air
conditioning specialist. Refer also to the
precautions given in Chapter 3.

camshaft sprocket, aligning the marks made
previously on the chain and the sprocket.
40Fit the sprocket to the inlet camshaft, with
the camshaft in the TDC position (ie with the
inlet camshaft sprocket timing mark in line
with the top edge of the cylinder head,
pointing to the inlet side of the engine see
paragraph 4). Again, turn the camshaft if
necessary to enable the sprocket to be fitted.
41With the sprocket fitted, fit the distributor
rotor shaft to the end of the camshaft, and
tighten the securing bolt finger-tight. Note that
it is acceptable for the timing chain to sag
slightly between the two pulleys. 
42Fit a new upper timing chain guide to the
plate at the front of the cylinder head.
43Turn the crankshaft clockwise until the
inlet camshaft begins to turn.
44If the chain tensioner plunger piston
protrudes from the cylinder, unlatch the piston by
pressing the chain tensioner arm down by hand.
45If the plunger piston is below the top
surface of the cylinder, a tool must be
fabricated to unlatch the piston (see
illustration). It is suggested that 2.5 mm
diameter welding rod is used to manufacture
the tool. Use the tool to release the piston as
follows.
46Carefully lift the chain tensioner arm with a
screwdriver, and insert the tool between the
tensioner arm and the piston. Remove the
screwdriver, and release the piston by
pressing the tensioner arm down by hand.
Carefully withdraw the tool once the piston
has been released.
47Tighten the camshaft sprocket securing
bolts to the specified torque, holding the
sprockets stationary as during removal.
48Turn the crankshaft clockwise through two
complete revolutions, and check that the
timing marks on the camshaft sprockets are
still aligned with the top face of the cylinder
head as described in paragraph 4.
49Turn the crankshaft clockwise through
another complete revolution, and check that
the timing marks on the camshaft sprockets
are facing each other, directly in line with the
top face of the cylinder head. 
50If the timing marks do not align as
described, the timing chain has been
incorrectly fitted (probably one chain link awayfrom the correct position on one of the
camshaft sprockets), and the chain should be
removed from the sprockets and fitted in the
correct position.
51Inspect the oil seal in the upper timing
chain cover. If the oil seal is in good condition,
the cover can be refitted as follows, but if the
seal is damaged, or has been leaking, a new
seal should be fitted to the cover. If necessary,
carefully prise the old oil seal from the cover
using a screwdriver, and drive in the new seal
using a suitable metal tube. Make sure that the
seal lip faces into the engine. Take care not to
damage the timing chain cover.
52Fit the upper timing chain cover using a
new rubber gasket. Great care must be taken
to avoid damage to the oil seal when passing
the seal over the end of the inlet camshaft.
Careful manipulation will be required (possibly
using a thin feeler blade) to avoid damage to
the oil seal sealing lip. Note that the oil seal
should be fitted dry.
53Refit the timing chain cover securing bolts
and studs in their original locations and tighten
them to the specified torque (see illustration).
54Remove the reinforcing sleeves from the
camshaft cover, and renew the rubber sealing
rings. Note that the four short reinforcing
sleeves fit at the front of the cover (see
illustration).
55Refit the camshaft cover using a new
gasket, and tighten the securing bolts and
studs to the specified torque.
Note: A valve spring compressor will be
required during this procedure. New valve
stem oil seals should be used on reassembly.
Dismantle the cylinder head as described in
paragraphs 2 to 4, Section 12, PartA of this
Chapterand reassemble the head as
described in paragraphs 4 to 6, Section 42,
Part A of this Chapter, noting the following
points:
a)Ignore the references to the special tool.
b)Double valve springs are used on all the
valves (see illustration).
c)Refer to the following Section if the
cylinder head is to be inspected and
renovated.Refer to Part A, Section 34 of this Chapter,
noting the following points.
a)Valve and valve seat cutting and
regrinding can be carried out using
conventional tools.
b)The cylinder head cannot be resurfaced,
and if the surface distortion exceeds the
specified limits, the cylinder head must be
renewed.
Note: Once the timing chain has been
removed from the camshaft sprockets, do not
turn the crankshaft until the timing chain has
been correctly refitted - this is to prevent
contact between the valves and pistons. A
new timing chain tensioner plunger assembly,
a new upper timing chain cover gasket, and a
new camshaft cover and reinforcing sleeve
sealing rings must be used on refitting.
1If the engine is in the vehicle, carry out the
following operations.
a)Disconnect the battery negative lead.
b)On carburettor models, remove the air
cleaner.
c)On fuel-injection models, remove the air
inlet hose, plenum chamber, and air
cleaner lid as an assembly.
