Oil Filter
The oil filter is a replaceable cartridge installed on an
adapter in the centre of the vee. An internal bypass
facility permits full flow bypass if the filter is blocked.
NOTE: In service care must be taken when removing
the oil filter to minimise oil drips and spillage into the
engine vee and cam covers:
•Do not use air/power tools
•Unscrew oil filter cap 4-5 turns
•Leave for a minimum of 1 minute to allow to drain
•Remove cap, ensuring minimal oil spillage
•Replace oil filter element into...

EXHAUST MANIFOLD
LH exhaust manifold1RH exhaust manifold2
The exhaust manifolds are cast from steel alloy and are
unique for each cylinder bank. They are sealed to the
cylinder head by means of a steel gasket. Sacrificial
plastic sleeves are used to align the manifolds. These
sleeves must be changed when refitting the manifolds.
Spacers on the securing bolts allow the manifolds to
expand and retract with changes of temperature while
maintaining the clamping loads.
Each manifold has a connection for the...

Crossover Pipe
A crossover pipe carries the exhaust gasses from the
RH exhaust manifold to the turbocharger on the LH
exhaust manifold. The crossover pipe is located at the
rear of the engine and is routed across the top of the
transmissions bell housing.

GENERAL
The Evaporative emission (EVAP) control system
reduces the level of hydrocarbons released into the
atmosphere by fuel vapor venting from the fuel tank.
The system comprises a charcoal canister, purge valve
and interconnecting vent pipes and hoses. The vent pipes
are connected to the system components using quick
release connectors....

The purge valve is located at the rear of the engine, on
a bracket which is attached to the transmission bell
housing. The purge hose is routed from the purge valve,
along the left hand side of the air intake manifold, to
the elbow assembly which locates the electric throttle.
The purge hose is connected, at the right hand rear of
the engine, with a quick release coupling to the purge
line which runs parallel with the fuel feed line along the
top of the fuel tank to the charcoal canister.
The purge hose...

Charcoal canister tank vent hose connection6
The charcoal canister is located in a central position,
forward of the spare wheel. It is attached at the rear with
two bolts which screw into the spare wheel carrier. At
the front, the canister has two lugs which locate in the
parking brake module support bracket.
The canister on ROW vehicles has a capacity of 1400
cc (85.4 in3).
The canister on NAS vehicles has a capacity of 3000
cc (183 in3).
The canister has three ports which allow for the
attachment of...

During normal vehicle operation, the ECM energises
the heating element in the pump to prevent condensation
formation and possible incorrect current readings.
Leaks are classified as:
•Minor - equivalent to a hole diameter of 0.5 to 1.0
mm (0.02 to 0.04 in)
•Major - equivalent to hole diameter of 1.0 mm (0.04
in) or greater.
The ECM performs a check for major leaks each time
the ignition is switched off, providing the following
conditions are met:
•The ECM is in power down mode for more than 3
seconds...
