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.

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.

The V6 engine fitted to the Granada is only
available in fuel-injected form. Mechanically,
the design of the engine is well-established,
and it is improved by the latest fuel, ignition and
engine management systems (see illustration).
The combined crankcase and cylinder block
is made of cast iron, and houses the pistons,
crankshaft and camshaft. The sump is
attached to the bottom of the crankcase and
the cylinder heads to the top.
The cylinder heads are of the crossflow
design, the inlet manifold being located
between them and the exhaust manifolds
being on the outboard sides. The overhead
valves are operated by tappets, pushrods and
rockers from the centrally located camshaft.
Camshaft drive is by gears (2.8 litre) or chain
(2.4 & 2.9 litre).
The crankshaft runs in four main bearings.
Endfloat is controlled by thrust flanges on the
No 3 bearing shells. The connecting rods are
selected so that all are in the same weight class.
Aluminium alloy pistons are used. The
gudgeon pins are an interference fit in their
connecting rods.The lubrication system is of the usual wet
sump, pressure fed type, with a full-flow
disposable canister oil filter. The oil pump is
driven by a shaft which engages in the bottom
of the distributor drivegear.
The following operations can be carried out
without removing the engine, although some
work will be easier and quicker with the engine
removed.
a)Removal and refitting of the cylinder
heads
b)Removal and refitting of the sump and oil
pump
c)Removal and refitting of the timing gears
d)Removal and refitting of the pistons,
connecting rods and big-end bearings
e)Renewal of the engine mountings
f)Removal and refitting of the flywheel
g)Renewal of the crankshaft front and rear
oil seals
h)Removal and refitting of the camshaft
(after removal of the cylinder heads,
tappets and timing gears)The engine must be removed for the
following operations:
a)Renewal of the crankshaft main bearings
b)Removal and refitting of the crankshaft
The engine is removed from above, without
the transmission. Removal with the
transmission is not recommended because of
the weight and unwieldiness of the combined
units.

complete with fuel rail and injectors. Discard
the gasket.
33Disconnect the exhaust downpipe(s) from
the manifold(s).
34Disconnect the earth straps from the rear
of the left-hand cylinder head and release the
cable retaining clamp.
35Unscrew and remove the spark plugs.
36Unscrew the cylinder head bolts using the
reverse of the tightening sequence (see
illustration 38.5). Obtain new bolts for refitting.
Remove the cylinder head(s) and discard the
gasket(s).
Proceed as described in Part A, Section 16
of this Chapter but note that there are 24 bolts
retaining the sump, not 23.
The procedure is described for the engine in
the vehicle. With the engine removed, the
preliminary steps can be ignored.

27The inlet manifold bolts should be
retightened to the specified torque in the correct
sequence. This will mean disconnecting the air
hoses from the throttle valve housing, the
vacuum hose from the left-hand rocker cover,
and the wiring connector from the idle speed
control valve and throttle valve potentiometer.
Remove the plenum chamber, place it to one
side, then release the fuel rail bolts but do not
disconnect the fuel pipes. It may also be
necessary to remove the distributor again to
gain access to one of the bolts.
See Chapter 1, Section 23.
1Refer to Section 7 and refit the items listed.
2If the oil cooler and its threaded bush were
removed, refit them as follows (see
illustration).
3Screw the new bush into the cylinder block.
Apply Omnifit Activator “Rapid” (to Ford
specification SSM-99B-9000-AA) to the
exposed threads of the bush and to the inside
of the threaded sleeve.
4Apply one drop of Omnifit Sealant “300
Rapid” (to Ford specification SSM-4G-9003-
AA) to the leading threads of the bush.Do not
use more than one drop, otherwise sealant
may get into the lubrication circuit.
5Fit the cooler, using a new gasket, and
secure with the threaded bush. Make sure that
the coolant pipes are positioned at the correct
angle (see illustration),then tighten the
threaded sleeve to the specified torque.
6Fit a new oil filter element, oiling its sealing
ring prior to installation. Tighten the filter
approximately three-quarters of a turn beyond
the point where the seal contacts the cooler
face. Do not use any tool to tighten the filter.
Refer to Part A, Section 49, paragraphs 1 to
9 of this Chapter. Before starting the engine,
refer to the following Section.1Refer to Part A, Section 51 of this Chapter.
2When conventional (hexagon-headed)
cylinder head bolts are fitted, they must be re-
tightened after the engine has warmed up.
Proceed as follows.
3Stop the engine and remove the rocker covers.
4Working in the sequence used for
tightening, slacken one cylinder head bolt a
quarter turn, then re-tighten it to the Stage 4
specified torque. Repeat in sequence for all
the cylinder head bolts.
5Tighten the inlet manifold bolts.
6Check the valve clearances.
7Refit the rocker covers and other disturbed
components.
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.
