13Apply a sealing compound to the faces of
the cylinder block and sump at the points
indicated(see illustration).
14Apply suitable thread-locking compound
to the sump securing studs and bolts, then
locate the sump on the cylinder block and fit
the securing nuts and bolts, but do not fully
tighten them at this stage.
15Align the sump so that the end faces and
the cylinder block are flush. To do this, use a
straight-edge. If the sump cannot be
positioned so that the faces of the cylinder
block and sump are flush, measure the
difference in height using a feeler blade as
shown (see illustration).
16Tighten the sump securing nuts and bolts
to the specified torque, then repeat the
measurement made in paragraph 15. If the
end faces of the sump and cylinder block are
not flush, suitable shims must be fitted
(available from a Ford dealer) between the
sump and the gearbox/transmission to
eliminate the clearance when mating the
engine to the gearbox/transmission. Note that
shims should be fitted at both sides of the
sump, as required. Select suitable shims from
those listed in the following table.
Clearance measuredShims required
0 to 0.25 mmNo shims required
0.25 to 0.29 mm0.15 mm (silver)
0.30 to 0.44 mm0.30 mm (light blue)
0.45 to 0.59 mm0.45 mm (red)
0.60 to 0.75 mm0.60 mm (black)
17If the engine is in the vehicle, reverse the
procedure described in paragraphs 3 to 8,
noting the following points.
a)Ensure that the roadwheels and the
steering wheel are in the straight-aheadposition then align the marks made on
removal and reconnect the intermediate
shaft to the steering gear. Tighten the
clamp bolt to the specified torque.
b)Fill the engine with the correct grade and
quantity of oil.
c)Refit the engine adapter plate and the
flywheel/driveplate.
d)Refit the gearbox or automatic
transmission, as applicable, ensuring that
the required shims are fitted between the
sump and the gearbox/transmission.
e)Tighten all fixings to the specified torque
where applicable.
Note: A suitable puller will be required to
remove the crankshaft pulley. A new
crankshaft pulley bolt, a new lower timing
chain cover gasket and a new oil pump gasket
must be used on refitting.
1If the engine is in the car, carry out the
following operations.
a)Disconnect the battery negative lead.
b)To Improve access, remove the radiator. It
will be difficult to remove the crankshaft
pulley with the radiator in place.
c)On fuel-injection models, remove the air
inlet hose, plenum chamber and air
cleaner lid as an assembly.
2Proceed as described in paragraphs 3 to 10
of Section 15.3Unscrew the four securing bolts and
withdraw the oil pump from the cylinder block
(see illustration). Recover the gasket and
discard it.
4If desired, the pump can now be dismantled
and inspected.
5Thoroughly clean the mating faces of the
pump and the cylinder block.
6Prime the pump by injecting clean engine oil
into it and turning it by hand.
7Place a new gasket on the oil pump flange,
ensuring that the gasket is correctly located so
that the holes align with the oil passages in the
pump.
8Fit the oil pump, and tighten the securing
bolts to the specified torque.
9Proceed as described in paragraphs 28 to 40
of Section 15.
10If the engine is in the vehicle, reverse the
operations described in paragraph 1.
1The oil pump can be dismantled for
cleaning, but if any of the components are
worn, the pump must be renewed as an
assembly.
2To dismantle the pump, proceed as follows.
3Unscrew the two securing bolts, and
remove the pump cover (see illustration).
4Lift the inner and outer rotors from the
pump casing.
5Unscrew the pressure relief valve plug from

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.

9Inspect the valve springs, if possible
comparing their free length with new springs.
Renew the springs anyway if they have been in
use for 20 000 miles (32 000 km) or more.
10Use a straight-edge and feeler blades to
check that the cylinder head mating faces are
not distorted. If they are, have the heads
resurfaced by an engineering works.
11Commence reassembly by oiling a valve
stem and inserting the valve into its guide.
Cover the collet grooves with adhesive tape
and press the new valve stem oil seal down
the stem, using a suitable tube to press the
seals home. Note that the inlet valve seals are
rubber and the exhaust seals nylon. On the 2.8
litre engine, oversize exhaust valve seals must
be used when valves with oversize stems are
fitted. Remove the adhesive tape.
12Fit the valve spring and spring retainer.
Compress the spring and fit the collets, using
a dab of grease to hold them in position.
Carefully release the compressor.
13Tap the valve stem smartly with a mallet to
seat the components.
14Repeat the process on the remaining valves.
Refer to Part A, Section 28 of this Chapter.
The main bearing caps should be fitted, and
their bolts tightened to the specified torque,
when making bore measurements.
Refer to Part A, Section 29 of this Chapter.
1Refer to Part A, Section 27 of this Chapter for
the examination procedure. Note that regrinding
of this crankshaft is not permitted, so if significant
journal wear is present, a new crankshaft (and
new bearing shells) must be fitted.
2As with the SOHC engine, oversize main
bearing parent bores may be encountered.
These are marked with paint stripes on the
bearing caps, corresponding paint marks on
the bearing shells and identification codes on
the backs of the bearing shells.
3On the 2.4 litre engine, separate
thrustwashers are used to control crankshaft
endfloat. On the 2.9 litre engine, No 3 main
bearing shells have integral thrust flanges.
2.8 litre engine
1If oil pump wear is suspected, check the
cost and availability of new parts and the cost
of a new pump. Examine the pump and then
decide whether renewal or repair is the best
course of action (see illustration).2Remove the pick-up pipe and strainer.
3Note the position of the oil pump cover
relative to the body, then remove the bolts and
spring washers. Lift off the cover.
4Mark the rotor faces so that they can be
refitted the same way round, then remove
them from the body.
5Remove the pressure relief valve plug by
piercing it with a punch and levering it out.
Withdraw the spring and plunger.
6Thoroughly clean all parts in petrol or paraffin
and wipe dry using a non-fluffy rag. The
necessary clearances may now be checked
using a machined straight-edge (a good steel
rule) and a set of feeler blades. The critical
clearances are between the lobes of the centre
rotor and convex faces of the outer rotor;
between the rotor and pump body; and between
both rotors and the end cover plate (endfloat).
The clearances are given in the Specifications.
7Endfloat may be measured by refitting the
rotors, placing the straight-edge across the
bottom of the pump and measuring the clearance
between the two rotors and the straight-edge.
8New rotors are only available as a pair. If the
rotor-to-body clearance is excessive, a
complete new pump should be fitted.
9Commence reassembly by lubricating the
relief valve plunger. Fit the plunger and spring.
10Fit a new relief valve plug, flat side
outwards and seat it with a drift, until it is flush
with the pick-up pipe mating face.
11Lubricate the rotors and fit them,
observing the marks made when dismantling if
applicable.
12Fit the cover and secure it with the bolts
and spring washers. Tighten the bolts to the
specified torque.
13Fit the pick-up pipe and strainer, using a
new gasket.
14Temporarily insert the driveshaft into the
pump and make sure that the rotors turn freely.
15A new or overhauled pump must be
primed before fitting.2.4 & 2.9 litre engines
