Cylinder Heads
The aluminium gravity die cast cylinder heads are
unique to each cylinder bank. Eight deep-seated bolts,
to reduce distortion, secure each cylinder head to the
cylinder block. The cylinder head bolts are located
beneath the camshafts, four under the inlet camshaft
and four under the exhaust camshaft. Two hollow
dowels align each cylinder head with the cylinder block.
NOTE: The cylinder head bolts are not accessible with
the camshafts fitted.
NOTE: The cylinder head cannot be reworked....

The cylinder head has four ports machined at each
cylinder location, two exhaust ports and two inlet ports.
One of the inlet ports is helical and functions as a swirl
port, the other is arranged laterally as a tangential port
and functions as a charge port.
The six fuel injection nozzles are centrally mounted;
one above each cylinder and each is fixed to the cylinder
head by means of a clamp and two M6 x 35 bolts.

Camshaft Position (CMP) sensor1
The CMP sensor locates through a hole in a flange on
the front LH side of the LH cylinder head. The exhaust
camshaft gear of the LH cylinder head incorporates a
trigger wheel, which is used in conjunction with the
sensor to measure engine position.
The engine lifting eyes are bolted to the cylinder head,
one at the front and two at the rear, one per cylinder
head.

Oil filler aperture3RH camshaft cover assembly4
The camshaft covers are manufactured from vinyl ester
composite. The RH bank camshaft cover incorporates
an outlet for the full load engine breather and the engine
oil filler cap. The LH bank camshaft cover incorporates
an outlet for the part load engine breather.
Silicon rubber in-groove gaskets seal the joints between
the camshaft covers and the cylinder heads. Together
with spacers and seals on the camshaft cover fasteners,
they also isolate the covers...

Fuel InjectorsBolt, 2 per injector1
Clamp2
Injectors3
The fuel injectors inject the quantity of fuel required
for all the engine operating conditions into the
combustion chambers. The quantity of fuel injected
during each working cycle is composed of a
noise-reducing pilot injection phase and a main injection
phase.
The six, side fed, piezo electrically controlled fuel
injectors are installed in the fuel rails. The start of fuel
injection and the quantity of fuel injected is controlled
directly by the...

Water outlet housing assembly, bleed valveC
The water outlet assembly connects the cooling channels
of the cylinder block to the cooling channels of the LH
and RH cylinder heads and provides the coolant outlet
for the EGR and coolant return.
LUBRICATION SYSTEM
General

The oil returns to the oil pan under gravity. Large drain
holes through the cylinder heads and cylinder block
ensure the quick return of the oil, reducing the volume
of oil required and enabling an accurate check of the
contents soon after the engine stops.
System replenishment is through the oil filler cap on
the RH camshaft cover.
With the exception of the pump and level gauge, all oil
system components are installed on the sump.
