(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.

1Wipe the bearing shell locations in the
crankcase with a soft, non-fluffy rag.
2Wipe the crankshaft journals with a soft,
non-fluffy rag.
3Fit the five upper half main bearing shells to
their locations in the crankcase. If the old
shells are being re-used, make sure they are
refitted to their old locations.
4Identify each main bearing cap and place in
order. The number is cast onto the cap and on
intermediate caps an arrow is also marked
which should point towards front of engine.
5Wipe the cap bearing shell location with a
soft non-fluffy rag.
6Fit the bearing half shell onto each main
bearing cap.
7Apply a little grease to each side of the
centre main bearing so as to retain the
thrustwasher.
8Fit the upper halves of the thrustwashers
into their grooves either side of the main
bearing. The slots must face outwards.
9Lubricate the crankshaft journals and the
upper and lower main bearing shells with
engine oil and locate the rear oil seal (with lip
lubricated) on the rear of the crankshaft.
10Carefully lower the crankshaft into the
crankcase.
11Lubricate the crankshaft main bearing
journals again and then fit No 1 bearing cap. Fit
the two securing bolts but do not tighten yet.12Make sure that the mating faces are clean,
then apply sealant (Loctite 518 or equivalent)
to the areas on the rear main bearing cap (see
illustration).
13Fit the rear main bearing cap. Fit the two
securing bolts, but as before do not tighten yet.
14Apply a little grease to either side of the
centre main bearing cap so as to retain the
thrustwashers. Fit the thrustwashers with the
tag located in the groove and the slots facing
outwards (see illustration).
15Fit the centre main bearing cap and the
two securing bolts, then refit the intermediate
main bearing caps. Make sure that the arrows
point towards the front of the engine.
16Lightly tighten all main cap securing bolts
and then fully tighten in a progressive manner
to the specified torque wrench setting.
17Check that the crankshaft rotates freely.
Some stiffness is to be expected with new
components, but there must be no tight spots
or binding.
18Check that the crankshaft endfloat is
within the specified limits by inserting a feeler
blade between the centre crankshaft web and
the thrustwashers.
19Make sure that the rear oil seal is fully
located onto its seating. Coat the rear main
bearing cap wedges with sealing compound,
then press them into position with the rounded
red face towards the cap (see illustration).
20Refit the oil pump and strainer.

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

removed, apply a liquid locking agent to its
tube before pressing it into the cylinder block.
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.

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.

9Extract the bearing shells, and recover the
thrustwashers, keeping them identified for
location.
10The crankshaft and bearings can be
examined and if necessary renovated.
11Commence refitting as follows(see
illustration).
12Wipe the bearing shell locations in the
crankcase, and the crankshaft journals with a
soft non-fluffy rag.
13If the old main bearing shells are to be
renewed (not to do so is a false economy,
unless they are virtually new) fit the five upper
halves of the main bearing shells to their
locations in the crankcase.
14Fit the thrustwashers to the centre main
bearing location, using a little grease to retain
them if necessary. The oil grooves in the
thrustwashers must face outwards (ie facing
the crankshaft webs). Note that where
standard thrustwashers have been fitted in
production, the centre main bearing is
unmarked, but if oversize (0.38 mm)
thrustwashers have been fitted, the centre
main bearing will carry a yellow paint mark.
15Lubricate the crankshaft journals and the
upper and lower main bearing shells with
clean engine oil, then carefully lower the
crankshaft into the crankcase.
16Lubricate the crankshaft main bearing
journals again, and then fit the main bearing caps
in their correct locations, with the arrows on the
caps pointing towards the front of the engine.
17Fit the main bearing cap bolts, noting that
the studded bolts secure bearing caps Nos 3
and 5.
18Lightly tighten all the securing bolts, then
progressively tighten all bolts to the specified
torque.
19Check that the crankshaft rotates freely.
Some stiffness is to be expected with newcomponents, but there must be no tight spots
or binding.
20Check that the crankshaft endfloat is
within the specified limits by inserting a feeler
blade between the centre crankshaft web and
the thrustwashers.
21Refit the sump mounting plate to the front
of the cylinder block, and tighten the securing
bolts to the specified torque.
22Carefully wind a thin layer of tape around
the rear edge of the crankshaft to protect the
oil seal lips as the rear oil seal is installed.
23Refit the crankshaft rear oil seal housing,
using a new gasket, and tighten the securing
bolts to the specified torque.
24Install the new oil seal with reference to
Section 24.
25With the oil seal installed, carefully pull the
tape from the edge of the crankshaft.
26Refit the pistons and connecting rods as
described previously in this Chapter.
27Refit the flywheel/driveplate, and the
timing chain and crankshaft sprocket.
Proceed as described in Part A, Section 27
of this Chapter, noting that the production
bearing undersizes are indicated as follows.
Yellow or red paint marks on crankshaft —
standard diameter main bearing journals.
Green line on crankshaft front counterweight
— main bearing journals 0.25 mm
undersize.
Green spot on counterweight — big-end
bearing journals 0.25 mm undersize.
Refer to Part A, Section 25 of this Chapter,
but note that the connecting rod bolts should
be renewed on reassembly, and when
renewing the cylinder head bolts, the latest
type bolts with hexagonal heads should
always be used.
Proceed as described in Part A, Section 35
of this Chapter, noting the following points.
a)If the cylinder head has been removed,
pay particular attention to the note at the
beginning of Section 18.
b)If removed during any dismantling
operations, new flywheel driveplate bolts
and connecting rod bolts must be used.
c)After reassembling the main engine
components, refer to paragraph 3 of
Section 14 and refit the ancillary
components listed.Refer to Part A, Section 51 of this Chapter,
but note that when the engine is first started, a
metallic tapping noise may be heard. This is
due to the timing chain tensioner plunger
assembly taking time to pressurize with oil,
resulting in a temporarily slack chain. The
noise should stop after a short time, once oil
pressure has built up.
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 dismantling
the 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.
