14Refit the other disturbed components.
15Run the engine and check that there are
no oil leaks from the rocker cover.
2.8 litre engine
16If the engine is in the vehicle, carry out the
preliminary steps:
a)Disconnect the battery negative lead
b)Remove the throttle mechanism cover, air
cleaner cover, airflow meters and inlet
trunking
c)Remove the HT leads from the spark plugs
and unclip them from the rocker cover
d)Unbolt and remove the rocker covers
17Although not essential, it will be easier to
turn the engine if the spark plugs are removed.
18Valve clearances must be adjusted with
the engine cold (less than 40°C/104°F).
19Turn the engine, using a spanner on the
crankshaft pulley bolt, until the crankshaft
pulley timing mark is aligned with the TDC
(zero) pointer on the timing cover and the
valves of No 5 cylinder are overlapping, ie the
exhaust valve is closing and the inlet valve is
opening. (No 5 cylinder is the middle one on
the left-hand bank - left being the vehicle’s
left, not necessarily to operator’s.) (see
illustration).
20When the valves of No 5 cylinder are in
this position, check the valve clearances of
No1 cylinder by inserting a feeler blade of the
specified thickness between the rocker arm
and the valve stem. Adjust the clearance, if
necessary, by turning the rocker arm adjustingscrew until the specified clearance is obtained
(see illustration).Inlet and exhaust valve are
different.
21If the engine is now rotated one-third of a
turn clockwise at the crankshaft, the valves of
No 3 cylinder will be overlapping and the
valves of No4 cylinder can be checked and
adjusted.
22Proceed to adjust the clearances
according to the firing order as follows. The
cylinders are numbered (see illustration)and
the valves are listed in their correct order,
working from the front of the engine:
Valves overlappingValves to adjust
No 5 cylinderNo 1 cylinder (in, ex)
No 3 cylinderNo 4 cylinder (in, ex)
No 6 cylinderNo 2 cylinder (in, ex)
No 1 cylinderNo 5 cylinder (ex, in)
No 4 cylinderNo 3 cylinder (ex, in)
No 2 cylinderNo 6 cylinder (ex, in)
23Refit the rocker covers, using new gaskets
if necessary. Tighten the rocker cover bolts to
the specified torque.
24If the engine is in the vehicle, refit the other
displaced components.
2.4 & 2.9 litre engines
25The operation for these engines is
essentially as described for the 2.8 litre
engine, noting that the valve arrangement is
changed (see illustrations).
Using a spanner of the appropriate size,
check each manifold securing nut in turn
whilst referring to the appropriate Sections in
Chapter 2C for tightening sequences and
torque loading figures.
Remove the radiator grille and clean any
leaves, insects etc. from the condenser coil
and fins. Be very careful not to damage the
condenser fins: use a soft brush, or a
compressed air jet, along (not across) the fins
(see illustration).

25.1 Cleaning the air conditioner
condenser fins
procarmanuals.com
1Remove the radiator grille being careful not
to damage the condenser fins.
2Check the refrigerant charge as follows. The
engine should be cold and the ambient
temperature should be between 18°and 25°C
(64°and 77°F).
3Start the engine and allow it to idle. Observe
the refrigerant sight glass(see illustration)
and have an assistant switch on the air
conditioning to fan speed III. A few bubbles
should be seen in the sight glass as the
system starts up, but all bubbles should
disappear within 10 seconds. Persistent
bubbles, or no bubbles at all, mean that the
refrigerant charge is low. Switch off the
system immediately if the charge is low and do
not use it again until it has been recharged.
4Inspect the refrigerant pipes, hoses and
unions for security and good condition. Refit
the radiator grille.
5The air conditioning system will lose a
proportion of its charge through normal
seepage typically up to 100 g (4 oz) per year -
so it is as well to regard periodic recharging as
a maintenance operation.
1Check the final drive oil level as follows.
2Position the vehicle over a pit, or raise it at
front and rear on ramps or axle stands (see
“Jacking”). The vehicle must be level.
3Wipe clean around the final drive filler/level
plug (see illustration).Unscrew the plug with
a hexagon key. Using a piece of bent wire as
a dipstick, check that the oil is no more than
10 mm (0.4 in) below the plug hole.
4If topping-up is necessary, use clean gear
oil of the specified type. Do not overfill.
Frequent need for topping-up can only be due
to leaks, which should be rectified.
5When the level is correct, refit the filler/level
plug and tighten it.
6There is no requirement for periodic oil
changing, and no drain plug is provided. Lubricate the transmission selector and
kickdown linkages with engine oil or aerosol
lubricant.
1Examine all steering and suspension
components for wear and damage. Pay
particular attention to dust covers and gaiters,
which if renewed promptly when damaged can
save further damage to the component
protected.
2At the same intervals, check the front
suspension lower arm balljoints for wear by
levering up the arms(see illustration).
Balljoint free movement must not exceed
0.5 mm (0.02 in). The track rod end balljoints
can be checked in a similar manner, or by
observing them whilst an assistant rocks the
steering wheel back and forth. If the lower arm
balljoint is worn, the complete lower arm must
be renewed.
3Check the shock absorbers by bouncing the
vehicle up and down at each corner in turn.
When released, it should come to rest within
one complete oscillation. Continued
movement, or squeaking and groaning noises
from the shock absorber suggests that
renewal is required.Position the vehicle over a pit, or raise it at
front and rear on ramps or axle stands.
Examine the driveshaft joint rubber gaiters.
Flex the gaiters by hand and inspect the folds
and clips. Damaged or leaking gaiters must be
renewed without delay to avoid damage
occurring to the joint itself
Check the tightness of the final drive
mounting bolts and the driveshaft flange
screws.
1Except on vehicles with a wax-based
underbody protective coating, have the whole
of the underframe of the vehicle steam-
cleaned, engine compartment included, so
that a thorough inspection can be carried out
to see what minor repairs and renovations are
necessary.
2Steam-cleaning is available at many
garages, and is necessary for the removal of
the accumulation of oily grime, which
sometimes is allowed to become thick in
certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-applied;
the dirt can then be simply hosed off.
3After cleaning, position the vehicle over a
pit, or raise it at front and rear on ramps or axle
stands.
4Using a strong light, work around the
underside of the vehicle, inspecting it for
corrosion or damage. If either is found, refer to
Chapter 12 for details of repair.
Periodically inspect the rigid brake pipes for
rust and other damage, and the flexible hoses
for cracks, splits or “ballooning”. Have an
assistant depress the brake pedal (ignition on)
and inspect the hose and pipe unions for
leaks. Renew any defective item without delay.
On 2.0 litre engines, good electrical contact
between the carburettor stepper motor
plunger and the adjusting screw is essential to
maintain a regular idle speed.
Clean the plunger and adjusting screw
contact faces with abrasive paper followed by
switch cleaning fluid. Switch cleaning fluid is
available from electronic component shops.

Steering and suspension
3Check for any abnormalities in the steering,
suspension, handling or road “feel”.
4Drive the vehicle, and check that there are
no unusual vibrations or noises.
5Check that the steering feels positive, with
no excessive “sloppiness”, or roughness, and
check for any suspension noises when
cornering, or when driving over bumps.
Drivetrain
6Check the performance of the engine,
clutch, transmission and driveshafts.
7Listen for any unusual noises from the
engine, clutch and transmission.
8Make sure that the engine runs smoothly
when idling, and that there is no hesitation
when accelerating.
9Where applicable, check that the clutch
action is smooth and progressive, that the
drive is taken up smoothly, and that the pedal
travel is not excessive. Also listen for any
noises when the clutch pedal is depressed.
10Check that all gears can be engaged
smoothly, without noise, and that the gear
lever action is not abnormally vague or
“notchy”.
Check the operation and
performance of the braking system
11Make sure that the vehicle does not pull to
one side when braking, and that the wheels do
not lock prematurely when braking hard.
12Check that there is no vibration through
the steering when braking.
13Check that the handbrake operates
correctly, without excessive movement of the
lever, and that it holds the vehicle stationary
on a slope.
14Test the operation of the brake servo unit
as follows. With the engine off, depress the
footbrake four or five times to exhaust the
vacuum. Start the engine, holding the brake
pedal depressed. As the engine starts, there
should be a noticeable “give” in the brake
pedal as vacuum builds up. Allow the engine
to run for at least two minutes, and then
switch it off. If the brake pedal is depressed
now, it should be possible to detect a hiss
from the servo as the pedal is depressed. After
about four or five applications, no further
hissing should be heard, and the pedal should
feel considerably firmer.1The power steering fluid dipstick is
incorporated in the reservoir filler cap. The
reservoir is mounted on the pump. Observe
scrupulous cleanliness when checking the
level or topping-up.
2The system should be at operating
temperature and the engine switched off.
Wipe clean around the reservoir filler cap.
Unscrew the cap, withdraw the dipstick and
wipe it with a clean lint-free rag. Reinsert the
dipstick, screw the cap home, then unscrew it
again and read the level on the dipstick. It
should be up to the MAX or upper HOT mark
(depending on the dipstick markings) (see
illustration).
3Top-up if necessary with clean fluid of the
specified type. Check for leaks if topping-up is
frequently required.
4If the level is checked cold, use the MIN or
FULL COLD mark on the dipstick for reference.
Recheck the level at operating temperature.
On carburettor models, remove the air
cleaner cover and check that the automatic
choke is opening fully when the engine is hot.
Run the engine until it reaches normal
operating temperature. Stop the engine and
immediately restart it. If the engine fails to start
cleanly and immediately then refer to either
Chapters 4 or 5 and check fuel feed
adjustments.

7Release the two clips or screws which
secure the distributor cap. Remove the cap
(see illustration).
8Note that if the distributor cap is secured by
clips, the engine must not be cranked with the
cap removed. This is because it is possible for
a spring clip to foul the rotating parts of the
distributor and cause damage.
9Remove the rotor arm. It may simply pull off,
or it may be secured by two screws (see
illustration). The rotor arm tips may be coated
with silicone grease - if so, do not rub it off.
10Clean the HT leads and distributor capwith a dry cloth. Scrape any corrosion or other
deposits from the connectors and terminals.
Also clean the coil tower.
11Renew the HT leads if they are cracked,
burnt or otherwise damaged. If a multi-meter
is available, measure the resistance of the
leads. The desired value is given in the
Specifications of Chapter 5.
12Renew the distributor cap if it is cracked
or badly burnt inside, or if there is evidence of
“tracking” (black lines marking the path of HT
leakage). If there is a carbon brush at the
centre of the cap, make sure that it moves
freely, and is not excessively worn.
13Clean the metal track of the rotor arm with
abrasive paper (but see paragraph 9 first).
Renew the arm if it is cracked or badly burnt.
14Commence reassembly by fitting the rotorarm to the distributor. It is positively located by
a notch or shaped pegs so it cannot be fitted
the wrong way round. Tighten the securing
screws, when applicable.

The cylinder head is of crossflow design
with the inlet manifold mounted on the left-
hand side and the exhaust manifold mounted
on the right-hand side.
Lubrication is by means of a bi-rotor pump
which draws oil through a strainer located
inside the sump, and forces it through a full-
flow filter into the engine oil galleries where it
is distributed to the crankshaft, camshaft and
auxiliary shaft. The big-end bearings are
supplied with oil via internal drillings in the
crankshaft.The undersides of the pistons are
supplied with oil from drillings in the big-ends.
The distributor shaft is intermittently supplied
with oil from the drilled auxiliary shaft. The
camshaft and cam followers are supplied with
oil via a drilled spray tube from the centre
camshaft bearing.
A semi-closed crankcase ventilation system
is employed whereby piston blow-by gases
are drawn into the inlet manifold via an oil
separator and on carburettor models a control
valve.
The following operations can be carried out
without removing the engine, although the
work may be easier and quicker with the
engine removed:
a)Removal and refitting of the cylinder head
b)Removal and refitting of the camshaft
(after removing the cylinder head)
c)Removal and refitting of the timing belt

a)Renewal of the crankshaft main bearings
b)Removal and refitting of the crankshaft
The engine may be lifted out either on its
own or together with the gearbox. Unless work
is also necessary on the gearbox it is
recommended that the engine is removed on
its own. Where automatic transmission is
fitted, the engine should be removed on its
own owing to the additional weight. If the
engine and gearbox are removed together,
they will have to be tilted at a very steep angle;
make sure that the range of the lifting tackle is
adequate.1Disconnect the battery negative lead.

hose from the thermostat housing
c)Remove the accessory drivebelt(s)
2Unscrew the bolts and withdraw the timing
cover. Note the location of the cover in the
special bolt.
3Using a socket on the crankshaft pulley bolt,
turn the engine clockwise until the TDC (top
dead centre) notch on the pulley is alignedwith the pointer on the crankshaft front oil seal
housing, and the pointer on the camshaft
sprocket is aligned with the indentation on the
cylinder head. Note the position of the
distributor rotor arm. Mark the contact end of
the rotor in relation to the rim of the distributor
body.
4Slacken the timing belt tensioner retaining
bolts then pivot the tensioner pulley away from
the belt, to obtain maximum drivebelt free play
(see illustration). Hold the tensioner pulley in
this position and securely retighten the
retaining bolts.
5Mark the running direction of the belt if it is
to be re-used, then slip it off the camshaft
sprocket.
6Slacken the crankshaft pulley bolt. Prevent
the crankshaft from turning by engaging 5thgear (manual gearbox), or by removing the
starter motor and jamming the ring gear teeth.
Alternatively, if the pulley has peripheral bolt
holes, screw in a couple of bolts and use a
lever between them to jam it. Do not allow the
crankshaft to turn very far, or piston/valve
contact may occur.
7Remove the bolt and washer and withdraw
the pulley. If the pulley will not come off easily,
refit the bolt part way and use a puller (see
illustration). A puller will almost certainly be
required on fuel-injection models.
8Remove the guide washer from in front of
the crankshaft sprocket, then remove the
timing belt (see illustration). Do not kink it or
get oil on it if it is to be re-used.
9Remove the crankshaft sprocket using a
puller if necessary (see illustration).
