(1.0 in) either side of the spreader gap. Fit the
tapered lower compression ring with the TOP
mark towards the top of the piston and the gap
150°from the spreader gap, then fit the upper
compression ring with the gap 150°on the
other side of the spreader gap. Note that the
compression rings are coated with a
molybdenum skin which must not be damaged.
7Note that the compression rings are made
of cast iron, and will snap if expanded too far.
Examine the surface of the camshaft
journals and lobes and the cam followers for
wear. If excessive, considerable noise would
have been noticed from the top of the engine
and a new camshaft and followers must be
fitted.
Check the camshaft bearings for wear and if
necessary have them renewed by a Ford
garage.
Check the camshaft lubrication tube for
obstructions and make sure that the jet holes
are clear. Obstruction of the holes can be due
to sludge build-up which occurs when regular
oil changes have been neglected.
Examine the auxiliary shaft for wear and
damage and renew it if necessary.
If the auxiliary shaft endfloat is outside the
limits given in the Specifications fit a new
thrust plate. If this does not bring the endfloat
within limits, renew the shaft.
Whenever the timing belt is removed it is
worthwhile renewing it, especially if it has
covered a high mileage. This is more important
on the 2.0 litre engine where stripped teeth on
the timing belt can cause the pistons to foul
the valves.If the ring gear is badly worn or has missing
teeth, it should be renewed. The old ring can
be removed from the flywheel by cutting a
notch between two teeth with a hacksaw and
then splitting it with a cold chisel. Wear eye
protection when doing this.
To fit a new ring gear requires heating the
ring to 204°C (400°F). This can be done by
polishing four equal sections of the gear,
laying it on a suitable heat resistant surface
(such as fire bricks) and heating it evenly with
a blow lamp or torch until the polished areas
turn a light yellow tinge. Do not overheat or the
hard wearing properties will be lost. The gear
has a chamfered inner edge which should go
against the shoulder when put on the flywheel.
When hot enough place the gear in position
quickly, tapping it home if necessary and let it
cool naturally, without quenching.
1This operation will normally only be required
at comparatively high mileages. However, if
persistent pinking occurs and performance
has deteriorated even though the engine
adjustments are correct, decarbonising and
valve grinding may be required.
2With the cylinder head removed, use a
scraper to remove the carbon from the
combustion chambers and ports. Remove all
traces of gasket from the cylinder head
surface, then wash it thoroughly with paraffin.
3Use a straight-edge and feeler blade to
check that the cylinder head surface is not
distorted. If it is, it must be resurfaced by a
suitably equipped engineering works.
4If the engine is still in the car, clean the
piston crowns and cylinder bore upper edges,
but make sure that no carbon drops between
the pistons and bores. To do this, locate two
of the pistons at the top of their bores and seal
off the remaining bores with paper and
masking tape. Press a little grease between
the two pistons and their bores to collect any
carbon dust; this can be wiped away when the
piston is lowered.5Examine the heads of the valves for pitting
and burning, especially the exhaust valve
heads. Renew any valve which is badly burnt.
Examine the valve seats at the same time. If
the pitting is very slight, it can be removed by
grinding the valve heads and seats together
with coarse, then fine, grinding paste.
6Where excessive pitting has occurred, the
valve seats must be recut or renewed by a
suitably equipped engineering works.
7Valve grinding is carried out as follows.
Place the cylinder head upside down on a
bench on blocks of wood.
8Smear a trace of coarse carborundum paste
on the seat face and press a suction grinding
tool onto the valve head. With a semi-rotary
action, grind the valve head to its seat, lifting
the valve occasionally to redistribute the
grinding paste. When a dull matt even surface
is produced on both the valve seat and the
valve, wipe off the paste and repeat the
process with fine carborundum paste as
before. A light spring placed under the valve
head will greatly ease this operation. When a
smooth unbroken ring of light grey matt finish
is produced on both the valve and seat, the
grinding operation is complete.
9Scrape away all carbon from the valve head
and stem, and clean away all traces of
grinding compound. Clean the valves and
seats with a paraffin soaked rag, then wipe
with a clean rag.
10If the guides are worn they will need
reboring for oversize valves or for fitting guide
inserts. The valve seats will also need
recutting to ensure that they are concentric
with the stems. This work should be given to
your Ford dealer or local engineering works.
11If the valve springs have been in use
for 20 000 miles (32 000 km) or more, renew
them. Always renew the valve stem oil seals
when the valves are removed.
1To ensure maximum life with minimum
trouble from a rebuilt engine, not only must
everything be correctly assembled, but it must
also be spotlessly clean. All oilways must be
clear, and locking washers and spring washers
must be fitted where indicated. Oil all bearings
and other working surfaces thoroughly with
engine oil during assembly.
2Before assembly begins, renew any bolts or
studs with damaged threads.
3Gather together a torque wrench, oil can,
clean rag, and a set of engine gaskets and oil
seals, together with a new oil filter.
4If they have been removed, new cylinder
head bolts and flywheel bolts will also be
required.

the two stages given in the Specifications(see
illustration).Tighten to the first stage in
circular sequence starting at point A, then
tighten to the second stage starting at point B.
Tighten to the third stage after the engine has
been running for twenty minutes.
5If the engine is in the vehicle, reverse the
steps taken to gain access to the sump.
1If it was removed, refit the adapter plate
(backplate) over the dowels on the rear of the
block.2Wipe the mating faces, then locate the
flywheel/driveplate on the rear of the
crankshaft.
3Coat the threads of the bolts with a liquid
locking agent before fitting. Note that the
manufacturers recommend using new bolts.
4Using a piece of angle iron, hold the
flywheel/driveplate stationary, then tighten the
bolts evenly to the specified torque in diagonal
sequence (see illustrations).

1Refit the thermostat and housing.
2Refit the timing belt tensioner if it was
removed, but do not tighten the bolts yet.
3If applicable, screw the cam follower ball-
pins in their correct locations (see
illustration).
4Oil the valve stems and insert the valves in
their correct guides.
5Wrap some adhesive tape over the collet
groove of each valve, then oil the oil seals and
slide them over the valve onto the guides. Use
a suitable metal tube if necessary to press
them onto the guides. Remove the adhesive
tape.
6Working on each valve in turn, fit the valve
spring and cap, then compress the spring with
the compressor and insert the split collets.
Release the compressor and remove it. Tap
the end of the valve stem with a non-metallic
mallet to settle the collets. If tool 21-005-A is
being used, first locate the camshaft in its
bearings.
7Refit the camshaft.1Drive the new oil seal into the camshaft front
bearing location on the cylinder head using a
suitable metal tube or socket (see
illustration). Smear the lip with engine oil.
2Lubricate the bearings with hypoid
SAE 80/90 oil, then carefully insert the camshaft.
3Locate the thrust plate in the camshaft
groove, then insert and tighten the bolts.
4Using feeler blades check that the endfloat
is as given in the Specifications.
5Lubricate the ball-pins with hypoid
SAE 80/90 oil, then fit the cam followers in
their correct locations and retain with the
spring clips. It will be necessary to rotate the
camshaft during this operation.
6Fit the oil supply tube and tighten the bolts.
7Fit the camshaft sprocket backplate and
sprocket. Insert and tighten the bolt while
holding the camshaft stationary with a spanner
on the lug (see illustration).
8Refit the cylinder head.
1Adjust the valve clearances. This work is
easier to carry out on the bench rather than in
the car.
2Turn the engine so that No 1 piston is
approximately 2 cm (0.8 in) before top deadcentre. This precaution will prevent any
damage to open valves.
3Make sure that the faces of the cylinder
block and cylinder head are perfectly clean,
then locate the new gasket on the block
making sure that all the internal holes are
aligned (see illustration). Do not use jointing
compound.
4Turn the camshaft so that the TDC pointer is
aligned with the indentation on the front of the
cylinder head.
5Lower the cylinder head onto the gasket.
The help of an assistant will ensure that the
gasket is not dislodged. Alternatively, make a
couple of guide studs by sawing the heads off
two old cylinder head bolts; remove the studs
when the head is in position.
6Lightly oil the heads and threads of the new
head bolts and insert them into their holes.
7Using the Torx key, tighten the bolts
progressively to the Stage 1 specified torque
in the indicated sequence(see illustration).
8In the same sequence tighten the bolts to
the Stage 2 specified torque.
9Wait five minutes, then tighten the bolts
through the angle specified for Stage 3, still
following the same sequence. (If the engine is
on the bench, it may be preferable to leave this
final stage until after refitting the engine, when
the problem of holding it still will not arise.)
10Refit the rocker cover, using a new gasket.
Make sure that the dovetail sections of the
gasket engage correctly (see illustration).
11Fit the rocker cover bolts and reinforcing
plates. Tighten the bolts as follows, referring to

13Refit and tension the timing belt as
described in the next Section.
1Fit the camshaft sprocket backplate and
sprocket. Insert the bolt, hold the camshaft or
sprocket and tighten the bolt to the specified
torque. 2Fit the auxiliary shaft sprocket with the ribs
towards the engine. Fit the sprocket bolt and
tighten it to the specified torque,
counterholding the sprocket with a bar
through one of the holes.
3Fit the crankshaft sprocket, chamfered side
inwards.
4Fit the timing belt over the camshaft
sprocket, but do not engage it with the other
sprockets yet. Be careful not to kink the belt. If
the old belt is being refitted, observe the
previously noted running direction (see
illustration).
5Refit the guide washer and the crankshaft
pulley. Fit the bolt and washer and tighten just
enough to seat the pulley, being careful not to
turn the crankshaft (see illustrations).
6Make sure that the TDC pointer on the
camshaft sprocket backplate is still aligned
with the indentation on the cylinder head.
7Turn the crankshaft by the shortest route to
align the TDC notch in the pulley with the
pointer on the oil seal housing.
8If the distributor is fitted, turn the auxiliary
shaft sprocket so that the rotor arm points to
the No 1 HT segment position.
9Fit the timing belt over the sprockets and
round the tensioner. Move the tensioner to
tension the belt roughly and nip up the
tensioner bolts.
10Turn the crankshaft through two full turns
clockwise, then 60°anti-clockwise (so it is
now at 60°BTDC)
11The belt tension should now ideally be
checked by applying Ford tension gauge 21-113to the longest run. Desired gauge readings are:
Used belt - 4 to 5
New belt - 10 to 11
12If the tension gauge is not available, a
rough guide is that belt tension is correct when
the belt can be twisted 90°in the middle of the
longest run with the fingers (see illustration).
13If adjustment of belt tension is necessary,
turn the crankshaft clockwise to bring No 1
cylinder to TDC(see illustration)then slacken
the tensioner bolts and move the tensioner to
increase or decrease belt tension. Tighten the
tensioner bolts.
14Turn the crankshaft 90°clockwise past
TDC, then anti-clockwise back to the 60°
BTDC position. Check the belt tension again.
15Repeat the above procedure until the belt
tension is correct.
16Tighten the tensioner bolts and the
crankshaft pulley bolt to the specified torques
(see illustration).
17Refit the belt cover and tighten its bolts.
18If the engine is in the vehicle, reverse the
preliminary steps given in Section 13.
19Check the ignition timing when the engine
is next run.
Refer to Section 9 and refit the components
listed. Delicate items such as the alternator
and distributor may be left until after the
engine has been refitted, if preferred.

1Make sure that the clutch is centred.
2Apply a smear of grease or anti-seize
compound to the gearbox input shaft splines.
3With the aid of an assistant, offer the
gearbox to the engine. If the input shaft is
reluctant to enter the clutch, rock the gearbox
slightly or turn the crankshaft back and forth.
Support the gearbox until it is engaged with
the dowels on the engine - do not leave it
hanging on the input shaft.4Refit the engine-to-bellhousing bolts, the
bracing strap and the starter motor.
1Sling the engine/gearbox unit so that it
hangs at an angle of approximately 45°.
2Lower the unit into the engine bay, at the
same time moving it towards the rear of the
vehicle. Have an assistant watch as the unit is
lowered to check that no pipes, wires etc are
fouled or trapped.
3Raise the gearbox as the engine is lowered
until the unit takes up its correct position.
Secure the engine bearers to the mountings
and refit the gearbox crossmember.
4The remainder of refitting is a reversal of the
removal procedure. Refer to Section 6. Also
refer to Section 49, paragraph 9.
5Before starting the engine, refer to Section 51.
1On manual gearbox models, check that the
clutch is centred correctly. Apply a smear of
grease or anti-seize compound to the gearbox
input shaft.
2On automatic transmission models, check
that the torque converter is fully engaged with
the transmission oil pump.
3Sling the engine so that it is roughly horizontal.Lift it and position it over the engine bay.
4Lower the engine into place. Have an
assistant watch as the unit is lowered to check
that no pipes, wires etc are fouled or trapped.
5Guide the engine onto the transmission,
raising or lowering the transmission slightly if
necessary. Do not place any weight on the
transmission input shaft. With manual gearbox
models, rock the engine gently from side to
side to encourage the input shaft to enter the
clutch.
6When the engine and transmission are fully
engaged, refit the engine-to-bellhousing bolts.
Do not overlook the earth strap.
7Lower the engine so that the engine bearers
engage with the mountings. Fit the mounting
nuts and remove the lifting tackle.
8On automatic transmission models, bolt the
torque converter to the driveplate.
9The remainder of refitting is a reversal of the
removal procedure. Note the following
additional points:
a)Refill the engine with oil
b)Check the transmission oil level if
necessary
c)Adjust the tension of the accessory
drivebelts
d)Adjust the throttle cable
e)Adjust the downshift cable when

See Chapter 1, Section 23.
1Make a final check to ensure that everything
has been reconnected to the engine and that no
rags or tools have been left in the engine bay.
2Check that oil and coolant levels are
correct.
3Start the engine. This may take a little longer
than usual as fuel is pumped up to the engine.
4Check that the oil pressure light goes out
when the engine starts.
5Run the engine at a fast tickover and check
for leaks of oil, fuel and coolant. Also check
power steering and transmission fluid cooler
unions, when applicable. Some smoke and
odd smells may be experienced as assembly
lubricant burns off the exhaust manifold and
other components.6Bring the engine to operating temperature.
Check the ignition timing then adjust the idle
speed (if applicable) and mixture.
7Stop the engine and allow it to cool, then re-
check the oil and coolant levels.
8If new bearings, pistons etc have been
fitted, the engine should be run in at reduced
speeds and loads for the first 500 miles (800
km) or so. It is beneficial to change the engine
oil and filter after this mileage.
1When engine performance is down, or if
misfiring occurs which cannot be attributed to
the ignition or fuel system, a compression test
can provide diagnostic clues. If the test is
performed regularly it can give warning of
trouble before any other symptoms become
apparent.
2The engine must be at operating
temperature, the battery must be fully charged
and the spark plugs must be removed. The
services of an assistant will also be required.
3Disable the ignition system by dismantlingthe coil LT feed. Fit the compression tester to
No 1 spark plug hole. (The type of tester which
screws into the spark plug hole is to be
preferred.)
4Have the assistant hold the throttle wide
open and crank the engine on the starter.
Record the highest reading obtained on the
compression tester.
5Repeat the test on the remaining cylinders,
recording the pressure developed in each.
6Desired pressures are given in the
Specifications. If the pressure in any cylinder
is low, introduce a teaspoonful of clean engine
oil into the spark plug hole and repeat the test.
7If the addition of oil temporarily improves
the compression pressure, this indicates that
bore or piston wear was responsible for the
pressure loss. No improvement suggests that
leaking or burnt valves, or a blown head
gasket, may be to blame.
8A low reading from two adjacent cylinders is
almost certainly due to the head gasket
between them having blown.
9On completion of the test, refit the spark
plugs and reconnect the coil LT feed.
