Thread: Disco TD5 - Raising Oil level - Any ideas?

Hi, I am wondering how you got on with the fuel dilution problem? I to have a 03 Disco and been having the problem since I bought the car in 05.

Austral Landrover in Brisbane have had 3 goes at trying to fix it but it is still leaking. It is much slower as it is registering 3.8% fuel in 10,000 kms. It was much higher when I first found it. They have replaced head, all o'rings nad thrust washers.

However now they are telling me that those engines will pass some diesel through to the oil by the injectors. Depending on where the engine stops the cam may be fully compressing the needle for an injector and this will release into the bore and seap past the rings. I find that hard to believe as I thought the injector needed an electrical pulse to open it. Anyhow they are monitoring mine over the nex 5000 kms. Mine has only done 80,000km.

A simple test for fuel in the oil is, when the engine is hot is to pull the dip stick out and let the oil drop on a piece of brown paper. If there is diesel in the oil it will spread out past the oil stain with a lighter color. That means you will have a dark stain in the middle and a light stain outside.
