Cylinder Head Gasket
LH cylinder head gasket1RH cylinder head gasket2
The multi-layered steel cylinder head gasket has cylinder
specific water flow cross-sections for uniform coolant
flow.

Fuel InjectorsFuel rail1
Injector2
Adapter3
The fuel injectors are installed in each of the two fuel
rails, one per cylinder head. The injectors are
electromagnetic solenoid valves controlled by the ECM.
Each injector nozzle locates in the cylinder head via an
injector insert adapter. An O ring seals each injector
to the fuel rail. The fuel jets from the injectors are
directed onto the back of the intake valves.

The camshaft covers are manufactured from
thermo-plastic. The LH cover incorporates a hole,
located directly above the camshaft reluctor, for the
camshaft position sensor. The LH cover also
incorporates the engine oil filler aperture.

Camshaft Position (CMP) SensorCMP sensor1
The CMP sensor is installed at the front of the LH
camshaft cover. It is a variable reluctance sensor that
provides an input to the ECM regarding the position of
the camshaft.
The reluctor for the camshaft position sensor is located
at the front of the LH camshaft. A flat, machined surface
near the front of each camshaft, enables the camshafts
to be locked during the valve timing procedure.

LUBRICATION SYSTEM
NOTE: Variant with oil cooler shown.
The lubrication system is of the full-flow filtration,
force-fed type.
Oil is drawn, via a strainer and pick-up pipe in the sump
into the jackshaft driven oil pump which has an integral
pressure relief valve. The strainer in the pick-up pipe
prevents any ingress of foreign particles from passing
through to the inlet side of the oil pump and damaging
the oil pump and restricting oil drillings. The oil pressure
relief valve in the oil pump opens if...

The oil pressure switch is located in the cylinder block
to sense the oil pressure level before the oil flow enters
the main gallery in the cylinder block. A warning lamp
in the instrument cluster is illuminated if low oil
pressure is detected.
Oil at reduced pressure is directed to each cylinder bank
via two restrictors in the cylinder block/cylinder head
locating dowels, one at the front on the LH bank and
the other at the rear on the RH bank. Oil then passes
through a drilling in the cylinder head to...

EXHAUST MANIFOLD
The dual wall stainless steel exhaust manifolds are
unique for each cylinder bank.
The exhaust manifolds are sealed to the cylinder heads
via metal gaskets.

GENERAL
The V8 petrol engine is a 4.4 litre, 8 cylinder, 90 degrees
Enclosed V unit, with 4 valves per cylinder, operated
by two overhead camshafts. The engine emissions
comply with ECD3 (European Commission Directive)
and US Federal Tier2 Bin 8 legislative requirements
and employs catalytic converters, electronic engine
management control, positive crankcase ventilation and
exhaust gas re-circulation to limit the emission of
pollutants. The cooling system is a low volume, high
velocity...

with thermo-plastic camshaft covers. The single-piece
oil sump is also cast aluminium. The fabricated stainless
steel twin skin exhaust manifolds are unique for each
cylinder bank and a moulded plastic acoustic cover is
fitted over the upper engine to reduce engine-generated
noise.
