Ford Granada 1985-1994, Owner'S Manual

27 The 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.
1 Refer to Section 7 and refit the items listed.
2 If the oil cooler and its threaded bush were
removed, refit them as follows (see
illustration).
3 Screw 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.
4 Apply 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.
5 Fit 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.
6 Fit 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.
1 Refer to Part A, Section 51 of this Chapter.
2 When conventional (hexagon-headed)
cylinder head bolts are fitted, they must be re-
tightened after the engine has warmed up.
Proceed as follows.
3 Stop the engine and remove the rocker covers.
4 Working 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.
5 Tighten the inlet manifold bolts.
6 Check the valve clearances.
7 Refit the rocker covers and other disturbed
components.
1 When 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.
2 The 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.
3 Disable 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.)
4 Have the assistant hold the throttle wide
open and crank the engine on the starter.
Record the highest reading obtained on the
compression tester.
5 Repeat the test on the remaining cylinders,
recording the pressure developed in each.
6 Desired 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.
7 If 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.
8 A low reading from two adjacent cylinders is
almost certainly due to the head gasket
between them having blown.
9 On completion of the test, refit the spark
plugs and reconnect the coil LT feed.
