Problem
High pitch whining noise from the lower engine area near the engine oil pump, which increases in frequency as the engine RPM advances.

Cause
Engine oil pump chain drive sprockets worn.

Solution
Remove and inspect timing chain and oil pump drive sprockets, guides, tensioners & chains for wear. Replace the worn engine oil pump chain drive module (46140) and timing chain kit (38362) following the vehicle manufacturers procedures and replace engine oil & filter.

Problem

Insufficient engine oil pressure; oil pressure warning lamp is illuminated after the engine oil and filter have been replaced.


Cause

Upon removing the old oil filter, a spring-loaded polyamide spigot valve – inside the housing – is released. When the valve moves upwards, it opens a passage for the oil accumulated in the housing to return to the sump. The installation of a new oil filter loads the spring and closes the drainage channel, ensuring that the engine oil flows through the filter during operation.

Problems can arise if the valve becomes stuck in the lower position after removing the old oil filter, which is usually indicated by the presence of ‘old’ oil in the housing. The spring will still be sprung-loaded and the valve can release (‘spring’ out) at any time. If the new oil filter is installed without the valve, the engine oil flows directly back into the sump after starting the engine. Consequently, the engine cannot reach the sufficient oil pressure – which then illuminates the oil pressure warning lamp.


Solution

Before installing the new oil filter, ensure the polyamide spigot valve is installed in the housing. If the valve is missing (having ‘sprung’ out as explained previously), find and clean the original valve, lubricate the ‘O’ ring-seals, and re-insert it into the housing. Alternatively, you can install a new valve – before installing the new oil filter. (Part No. 06J 115 679 E

The fuel filter replacement is a regular service item for Various Citroën, Fiat, Ford, Jaguar, Lancia, Land Rover, Mitsubishi, Peugeot models with 2.2 Diesel engines. However, there are a few points that should be considered.

There are four pipes that connect to the fuel filter, one of which has the fuel temperature sensor. Failure to reconnect this sensor after replacing the filter can cause the vehicle to go into ‘limp home’ mode and will restrict performance.

In some markets, the fuel filter is fitted with a ‘water in the fuel’ sensor which is located at the base of the filter. During fuel filter replacement, the sensor will need to be exchanged from the old filter onto the new filter and be tightened to 3 Nm.

After fuel filter replacement, it is imperative that the fuel system is purged of air before attempting to start the engine. Without bleeding the fuel system, the vehicle will not start. Connect a suitable fuel system bleed tool between the fuel line and filter, observing the fuel flow direction on the tool. (Fig. 2)

Prime the fuel filter by squeezing the hand pump several times until the pump becomes hard. Then, remove the fuel system bleed tool and reconnect the fuel line to the filter. Start the engine and check for leaks before refitting the engine cover.
Note:
If any water needs to be drained from this fuel filter during maintenance, the following procedure must be followed.

First, start the engine. Then, turn the bleed screw anti-clockwise until the O-ring seal is showing (Fig.3). Any separated water or air should come out from the bleed screw at the top of the filter. After bleeding the fuel filter, tighten the bleed screw clockwise when diesel starts to flow out – do this until the bleed screw is sealed. This filter design enables the draining of the water from the top of the filter since there is a plastic drain tube inside the filter. The heavy diesel fuel pushes the lighter water into the drain tube and out of the filter when the bleed screw is opened.
