The engine is of a four-cylinder, in-line,
single overhead camshaft type, mounted at
the front of the vehicle and available in 1.3,
1.6, 1.8 and 2.0 litre versions.
The crankshaft incorporates five main
bearings. Thrustwashers are fitted to the
centre main bearing in order to control
crankshaft endfloat.
The camshaft is driven by a toothed belt
and operates the slightly angled valves via
cam followers which pivot on ball-pins.
The auxiliary shaft which is also driven by
the toothed belt, drives the distributor, oil
pump and fuel pump.
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 followers are supplied with oil via adrilled 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 control valve.
Refer to Chapter 1, Section 8.
Refer to Chapter 1, Section 23.
Refer to Chapter 1, Section 35.
1When engine performance is poor, 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
disconnecting 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, piston or piston ring 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 the 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.
