compact and very stiff bottom end of the engine. The
cylinder heads are cast aluminium with a moulded
plastic camshaft cover. The single-piece oil sump is
formed from stamped steel. The cast iron 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.
TECHNICAL FEATURES
The technical features include:
•60 degree vee 6 cylinder engine with a CGI cylinder
block
•Plastic cylinder head cover
•Two light, high...

Piston Cooling Jets
Bolt1
Piston cooling jet2
Jets located in the cylinder block provide piston and
gudgeon pin lubrication and cooling. These jets spray
oil on to the inside of the piston, the oil then flows
through two internal wave shaped channels to help cool
each piston crown.
Lubrication oil is distributed through the cylinder block,
via the main oil gallery and channels bored in the block,
to all critical moving parts. These channels divert oil to
the main and big-end bearings via holes machined...

Connecting Rods and PistonsThe connecting rods are manufactured from
sinter-forged steel and have fracture-split bearing caps.
The bearing caps are produced by fracturing the
opposing sides of the connecting rod at the bearing
horizontal centre-line. As well as being easier to
manufacture, when reassembled the fractured surfaces
interlock to form a strong seamless joint. The cylinder
position is etched on adjoining sides of the joint to
identify matching connecting rods and bearing caps.
The selective...

When installing a connecting rod, ensure the back of
the connecting rod faces the centre of the vee.
The pistons are made from aluminium alloy and are
fitted with three rings. The piston crown incorporates a
pronounced bowl; this forms the combustion chamber,
which promotes swirl and turbulence necessary for...

Piston Installation
When installing pistons ensure the arrows on the piston
crowns all point to the front of the engine and the pistons
are located in the correct cylinder banks, i.e. cylinders
1, 2, 3 or cylinders 4, 5, 6.
NOTE: All pistons are common single grade/single part
number for all engines.
The piston top ring is a taper type and is fitted with the
taper to the top of the piston. All rings marked top are
assembled with top uppermost. All rings must be
spaced evenly around the piston before...

Coolant Pump

The coolant pump is installed on the LH side of the

The high-pressure fuel pump supplies the common rail
with fuel and is fixed to the rear of the cylinder block
in the centre of the vee. The pump is a 3 radial piston
type controlled by the EMS and belt driven from the
exhaust camshaft of the LH cylinder head.
