The engine may be lifted out either on its
own, or together with the manual
gearbox/automatic transmission. Unless work
is to be carried out on the manual
gearbox/automatic transmission, it is
recommended that the engine is removed on
its own. Where automatic transmission is
fitted, the engine should where possible be
removed on its own due to the additional
weight of the transmission. Note: The air conditioning system should
always be discharged by a Ford dealer or air
conditioning specialist.
Note: Refer to the warning in Section 8 before
proceeding. A suitable hoist and lifting tackle
will be required for this operation.

Warning: Vehicles equipped
with air conditioning:
Components of 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
connecting pipes. In such a case, the
system should be discharged by a Ford
dealer or air conditioning specialist. The
refrigerant is harmless under normal
conditions, but in the presence of a naked
flame (or a lighted cigarette) it forms a
highly toxic gas. Liquid refrigerant spilled
on the skin will cause frostbite. If
refrigerant enters the eyes, rinse them
with a diluted solution of boric acid and
seek medical advice immediately.

wires, hoses, pipes and cables, otherwise,
unbolt the manifold and move it to one side,
ensuring that it is adequately supported.
11If not already done, unclip any wires and
hoses from the camshaft cover, noting their
locations for use when refitting, and on fuel
injection models unbolt the bracing strut
securing the inlet manifold to the right-hand
side of the cylinder head.
12If desired, remove the thermostat and
housing, and the temperature gauge sender.
13Proceed as described in Section 21 for
cylinder head removal.
Refitting
14With the cylinder head refitted as
described in Section 21, proceed as follows.
15Where applicable, refit the temperature
gauge sender and the thermostat and
housing.
16Refit the manifolds and/or reconnect all
wires, hoses, pipes and cables, as applicable.
17Reconnect the exhaust downpipe to the
manifold, using a new gasket.
18Refit the coolant hose to the clip on the
exhaust manifold hot air shroud.
19Refit the spark plugs and reconnect the
HT leads.
20Reconnect the temperature gauge sender
wiring.
21Reconnect the coolant hoses to the
thermostat housing.
22Fill the cooling system.
23If not already done, refit any hoses and
wires to the camshaft cover, as noted during
removal, and on fuel injection models refit the
inlet manifold bracing strut. If splined type
cylinder head bolts have been used, leave
these operations until the bolts have been
finally tightened after running the engine.
24Refit the air cleaner on carburettor
models.
25Reconnect the battery negative lead.
26If splined type cylinder head bolts have
been used, start the engine and run it at 1000
rpm for 15 minutes, then stop the engine,
remove the air cleaner and the camshaft cover
as described previously, and finally tighten the
cylinder head bolts to the fourth stage (see
Specifications). Refit the camshaft cover on
completion, then refit any hoses and wires,
and on fuel injection models the inlet manifold
bracing strut. Refit the air cleaner.Note: Up to early 1984, splined type cylinder
head bolts were used, and from early 1984,
size T55 Torx bolts were used. Torx type bolts
must always be renewed after slackening. The
two types of bolts are interchangeable, but
only in complete sets - the two types must not
be mixed on the same engine. A suitable
special socket will be required for removal of
the bolts, and a new cylinder head gasket
must be used when refitting.
Removal
1With the manifolds removed, proceed as
follows.
2Remove the timing belt.
3Where applicable, disconnect the breather
hose from the camshaft cover.
4Unscrew the ten securing bolts and remove
the camshaft cover and gasket. Take care not
to lose the spacer plates which fit under the
bolt heads, where applicable.
5Using the relevant special socket, unscrew
the ten cylinder head bolts half a turn at a time
in the reverse order to that shown for
tightening.
6With the bolts removed, lift the cylinder
head from the block. If the cylinder head is
stuck, tap it free with a wooden mallet. Place
the cylinder head on blocks of wood to
prevent damage to the valves.
7Recover the gasket.
Refitting
8Commence refitting as follows.
9With the cylinder head supported on blocks
of wood, check and if necessary adjust thevalve clearances. This work is easier to carry
out on the bench rather than in the vehicle.
10Turn the crankshaft so that No 1 piston is
approximately 20 mm (0.8 in) before TDC.
This precaution will prevent any damage to
open valves.
11Make sure that the mating 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.
12Turn the camshaft so that the TDC pointer
on the camshaft sprocket backplate is aligned
with the indentation on the front of the
cylinder head.
13Lower the cylinder head onto the gasket.
The help of an assistant will ensure that the
gasket is not dislodged.
14Lightly oil the cylinder head bolt threads
and heads, then insert the bolts into their
locations in the cylinder head. Note that if the
original bolts were of the Torx type, new bolts
must be used when refitting.
15Using the relevant special socket, tighten
the bolts in the correct sequence (see
illustration)to the stages given in the
Specifications. Note that the bolt tightening
stages are different for splined and Torx type
bolts. If splined type bolts are used, they must
be finally tightened to the fourth stage after
the engine has been run for 15 minutes (see
Specifications).
16Check the condition of the camshaft
cover gasket and renew if necessary. Fit the
gasket to the camshaft cover, ensuring that
the locating tabs and dovetails are correctly
located, then refit the camshaft cover and
tighten the securing bolts in the order shown
(see Chapter 1, Section 23), ensuring that the
spacer plates are in position under the bolt
heads, where applicable.
17Where applicable, reconnect the breather
hose to the camshaft cover.
18Refit the timing belt.

Do not insert a lever into the
head joint as this may
damage the mating faces.

3Clean the oil seal housing, then drive in a
new seal using a suitable metal tube or
socket. Make sure that the seal lip faces into
the engine and lightly smear the lip with clean
engine oil.
4Refit the engine adapter plate and the
flywheel/driveplate.
Note: New gaskets and sealing strips will be
required for refitting, and sealing compound
will be required to coat the gasket faces.
Removal
1If the engine is in the vehicle, proceed as
follows, otherwise proceed to paragraph 12.
2Disconnect the battery negative lead.3Apply the handbrake, jack up the front of
the vehicle and support on axle stands (see
ÒJacking and Vehicle SupportÓ).
4Drain the engine oil into a container.
5Remove the starter motor, if necessary.
6Unscrew the nuts or bolts, as applicable,
securing the engine mountings to the
crossmember.
7Working in the engine compartment,
unscrew the bolt securing the intermediate
shaft to the steering column, swivel the clamp
plate to one side, and disconnect the
intermediate shaft.
8Where applicable, detach the brake lines
from the crossmember.
9Support the engine using a hoist, or a bar
and blocks of wood resting on the suspension
turrets (see illustrations). Attach the lifting
tackle to the engine lifting brackets on the
cylinder head. If using a support bar, the
engine may be lifted slightly by using the baras a lever before resting it on the wooden
blocks.
10Support the front crossmember with a
trolley jack, then unscrew the bolts securing
the crossmember to the underbody (see
illustration).
11Lower the crossmember just enough to
give sufficient clearance to remove the sump
(see illustrations).
12Unscrew the twenty-three securing bolts
and withdraw the sump (see illustration). If
the sump is stuck, carefully tap it sideways to
free it. Do not prise between the mating faces.
Note that if the engine has been removed, it is
preferable to keep the engine upright until the
sump has been removed to prevent sludge
from entering the engine internals.
13Recover the gaskets and sealing strips.
14Thoroughly clean the mating faces of the
cylinder block and sump.
Refitting
15Commence refitting by applying sealing
compound (available from a Ford dealer) to
the corners of the front and rear rubber
sealing strip locations in the cylinder block,
then press the sealing strips into the grooves
in the rear main bearing cap and the
crankshaft front oil seal housing (see
illustrations).
16Apply a little sealing compound to the
mating face of the cylinder block, then place
the sump gaskets in position, ensuring that
the end tabs locate correctly beneath the
rubber sealing strips (see illustration).
17Locate the sump on the gaskets and
loosely fit the securing bolts.
