I assume they mean where the fuel injector line connects to the top of the injector which is inside the rocker cover. Therefore you wont see a leak on the outside of the engine anywhere, but it mixes straight into the oil system.
Cheers

Yeah Alben is right.

The fuel injector lines go through the rocker cover and into the injectors.

They are prone to leaking and have no rubber seal. They are supposed to be replaced every 5 times they are removed. They are also sensitive to being torqued to within spec. In my case my lines were over-tightened by a mechanic and leaking significant amounts of diesel into the sump.

If they leak there would usually be no visibly external signs, but you would expect the level of oil in the sump to rise as it becomes diluted with diesel. Eventually the level of oil becomes so high and the oil so thin that it can seep past the seals in the turbo and the motor start to run on ithe oil/diesel mix that is in the sump.

Even with smaller amounts you'd also expect the oil to smell like diesel - at least a little bit.

The workshop manual at the following link has some images of the lines to get your heads around it and details of the torque specs for the lines. http://faq.out-club.ru/download/paje...7/index_M1.htm

To get access to the lines you need to remove the EGR and associated intake gear. Basically you need to remove everything on the passenger side of the motor that is above the intake manifold.

To torque the lines up again you need a fairly small torque wrench and some crows foot sockets for the wrench. Mitsubitshi recommend a specialised socket that they sell but it isn't necessary.

Its not the hardest job but takes a bit of time.

Did you run the fuel line pressure test with your scanner?

Have you been driving since removing the extra oil - does the sump level still rise?

Is it possible to have the sample of oil you removed tested?

I've done about 500kms since removing the extra oil , i will check tomorrow morning the level.

I only can scan it next week , scan gauge is not mine . '
I saw that it is a recurring problem, so I preferred to order it and do this repair first.(i hope the problem come from there)

I do not have the possibility of having it checked here, it would have to be sent to mainland France , but what i can say is that it doesn't smell like diesel at all .

For idling that is spot on. Some bi directional scan tools can do a fuel leak test to test the pipe connections, and also the return lines internally. This program ramps up the fuel pressure to maximum to allow you to look for leaks externally, and also check for oil dilution if it is an internal leak. Hopefully the scan tool you have access to can do this.



Also in the data section will be an oil dilution figure in cc. This is a calculation of how much fuel it expects to be in the oil as a normal byproduct of DPF regeneration. It is only a calculation though, not exact. this figure should be reset after every service, to allow for an accurate figure to be displayed. If the car is struggling to regenerate this will rise quite quickly and needs to be addressed.

Thanks for these presicion i will check oil dilution in data tomorrow or on monday

I don't think my scantool can do a fuel leak test not sure but i'll check it
