1. ENGINE MECHANICAL TROUBLE
SHOOTING

ENGINE MISSES AT IDLING SPEED
NOTE: For other causes of engine misfire,
refer to the Fuel and Engine Management
section.

(1) Blown head gasket: Check the cylinder com-
pressions and renew the he ad gasket as necessary.
(2) Burnt valves or seats in the cylinder head:
Check the cylinder compressions and overhaul the
cylinder head as necessary. (3) Broken or worn piston rings: Check the
cylinder compressions and renew the piston rings as
necessary.
(4) Weak or broken valve springs: Remove the
camshaft housing top cover and check the condition
of the valve springs. (5) Air leak at the inlet manifold gasket; Check
for air leaks by applying oil around the manifold
joints. Renew the gasket if an air leak is evident.
NOTE: Use a compre ssion gauge and check
the compression pressure in each cylinder as
described in the Engine Tune-up section. If
a low pressure reading is indicated in one or
more cylinders, remove the cylinder head for
gasket and valve inspection. Should the


gasket and valves prove satisfactory, inspect
the cylinder bores, pistons and rings.

Check for air leaks at the inlet manifold
by applying engine oil around the manifold
joints. If the oil can be seen or heard sucking
into the manifold or excessive smoke begins
to issue from the exhaust system, there is an
air leak at the inlet manifold.

NOISY VALVE OPERATION
(1) Faulty hydraulic tappets: Renew the faulty
tappet assemblies. (2) Weak or broken valve springs: Remove the
camshaft housing top cover and check the condition
of the valve springs. (3) Worn valve guides: Overhaul the cylinder
head as described in this section. (4) Worn rocker gear: Remove (he rocker gear
and check the components for wear.

Camshaft lobe wear is also a cause of noisy valve
operation.
BIG END BEARING NOISE
(1) Inadequate oil supply: Check the oil level in
the sump and the condition of the oil pump and relief
valve. Renew the oil filter.

(2) Excessive bearing clearance: Renew the bear-
ing shells, check and regrind the big end journals if
oval or tapered. (3) Thin oil or oil diluted by petrol or water:
Change to the correct oil grade. Check and rectify the
cause of the oil dilution. Ch eck that the engine is not
operating in overheat conditions.
(4) Low oil pressure: Check the engine oil level.
Check the pressure relief valve and spring and the oil
filter bypass valve. (5) Misaligned big end bearings: Align the con-
necting rods and renew the big end bearing shells.
NOTE: Big end bearing noise is indicated
by a metallic knock wh ich is usually loudest
at approximately 60 km/h with the throttle
Air leaks at the inlet manifold can be located by
applying engine oil around the suspect joints.

42 Engine
The cylinder block is a cast iron alloy, deep skirt
design and the crankshaft is supported in the cylinder
block by five precision insert replaceable main bear-
ings. Crankshaft end float is controlled by the flanged
centre main bearing. Connecting rods are I section
forgings equipped with precision insert replaceable big
end bearings. The gudgeon pins are an interference fit
in the connecting rod and a floating fit in the piston.

The cast aluminum pistons are equipped with
two compression rings and one oil control ring.

The twin rotor, involute gear oil pump is mounted
directly to the front face of the cylinder block. The
inner rotor is internally driven by the crankshaft. The
oil pump pressure relief valve is not adjustable, and
consists of a plunger and spring mounted in the oil
pump body.

The pump draws oil through a screen in the sump
and delivers it, via a full flow replaceable oil filter, to
the oil gallery from where it is distributed to the
hydraulic tappets, camshaft and crankshaft bearings
and to the overhead rocker and valve mechanism.
