of the seal and affect its performance. Seals are not interchangeable between 7,6 litre and 8,7 litre engines

due to seal thickness and material.

(E1) in the oil pump body engage with the holes (F2) in the timing case cover.

Caution: Fit a short setscrew at the 2 o-clock and the 3 o-clock positions.

12  Fit the remainder of the setscrews, and tighten all the setscrews.

Breather system

To clean

Operation 10-19

The engines have open breather systems. Breather elements are fitted inside the rocker cover assembly. The

breather elements (A1) separate lubricating oil from the crankcase gases. The oil is kept inside the rocker

cover (A2) and the crankcase gases pass through the breather element into an open breather pipe.

To renew the breather elements, see Operation 3-3.

Warning! Do not direct compressed air at your skin.

1  Remove the rocker cover, see Operation 3-1.

2  Remove the breather elements from the rocker cover (A2). Wash the breather element (A1) and the breather

pipe with an approved cleaning fluid and dry it with low pressure air.

3  Clean the rocker cover with an approved cleaning fluid and dry it with low pressure air.

4  Fit the rocker cover, see Operation 3-2.

General description (High-pressure system)

Lubricating oil from the main pressure rail passes into a channel in the timing case, then into the reservoir (A1)

for the high-pressure pump (A2).

The lubricating oil passes from the pump, under high-pressure, to a regulator valve (A8).

l   Some oil is discharged into the timing case (A9), by the valve.

l   Some oil is sent to the supply manifold (A4), then to the injector units (A3).

The high-pressure lubrication system provides the pressure to actuate the fuel injector units. The value of the

oil pressure can be altered by the engine management system, this pressure is known as “injection control

pressure”.

Three components work in a cycle to alter the injection control pressure:

1  A sensor (A5) in the supply manifold, sends a signal to the engine control module (A6).

2  The engine control module, uses the signal from the sensor to check the oil pressure. If the pressure needs

to be altered, the module sends a signal to the solenoid (A7) of the regulator valve (A8).

3  The regulator valve, changes the injection control pressure.

Any change of injection control pressure, will affect the sensor, and the cycle will start again.
