Oil Distribution
(see illustration on page 14)
Oil distribution within the block and cylinder
heads is similar to that of the V8 engine, the main
differences being in the filter and cooler
arrangement and the method of supplying the
VVT system.
Oil is drawn from the sump through the strainer
by the crankshaft driven pump, passes through
the externally mounted filter and oil cooler and
returns to the block. Distribution is via the main
gallery and crankshaft oilways to the lower
crankcase components and via branch feeds to
the chain tensioners and then cylinder head
components. Extra oilways in the cylinder heads
provide a built-in feed for the VVT components
(see VVT section).
Oil Pump
The oil pump is of the inner/outer rotor type with
the directly driven inner rotor located via flats on
the crankshaft and the body of the pump bolted
to the cylinder block. The oil pressure relief valveis located in the lower LH side of the pump. An
oil pick-up tube and strainer is bolted to the
pump inlet and projects directly down to the
sump. Oil foaming is reduced by the windage tray
bolted to the underside of the bedplate.

Oil Cooler and Filter Mounting
The oil filter and oil cooler are mounted slightly
away from the cylinder block on an aluminium
alloy adaptor which is an integral extension of the
LH engine mount. The oil filter is a replaceable
canister screw on type and the cooler is fixed by a
single through bolt to the adaptor. Both
components are connected to the cylinder block
through internal oilways in the adaptor casting
and via an interfacing filter mounting in the
block. A hollow bolt passes through the
adaptor/engine mount and screws into the centre
channel of the block filter mounting to provide
the oil return from the cooler to the cylinder
block.
The adaptor mounted oil cooler is an oil to water
heat exchanger and the coolant matrix is
connected via hoses into the main coolant system
at the radiator bottom hose (see Cooling System).

Engine Oil Pressure (EOP) and Oil
Temperature (EOT) Sensors
EOP and EOT sensors are fitted on the LH side of
the cylinder block in the return feed from the oil
cooler. The oil temperature is monitored to
provide data for the VVT system.

Cylinder Head
The cylinder head incorporates the modifications
first introduced for the AJ27 engine except for the
camshaft sensor ring and cam cover.
Camshaft Sensor Ring
Cam position sensing is similar to that used on the
AJ27 engine, except that the sensor ring fitted to
each inlet camshaft has five triggering teeth.
Camshaft Covers
To improve accessibility, an extension tube is
fitted to the oil filler hole on the bank 2 cam
cover. Due to the position of the throttle and air
intake ducting, the part load breather outlet is
taken from bank 1 cam cover and the full load
breather outlet from bank 2 (the reverse of AJ27).
Front Cover
The front cover is modified from the AJ27 to
include a mounting boss for a new idler pulley
(see Front End Accessories Drive).
Lubrication
The lubrication system includes the uprated oil
pump (for the linear VVT system) and the same oil
temperature sensor as fitted to the AJ27 engine.
The oil sump and pan are modified as described
on page 46.
The external oil system components are located
laterally across the front of the sump body and
consist of an oil filter, oil cooler and oil filter head
assembly. The oil cooler is an oil to water heat
exchanger similar to the V6 oil cooler and the
cooler matrix is also connected via hoses to a
circulator orifice in the radiator bottom hose (see
Cooling System). The oil filter screws on to the
cooler which connects to the sump body through
an adaptor, the oil filter head assembly.
