Thread: OIL GURUS - ADVICE NEEDED.

The injectors in D2s are very robust and long lived and the fuelling is usually well controlled by the ECU.

I would be looking at the injector seals and orings if anything, particularly the orings as raw fuel can then leak into the oil.

Regards PhilipA

thanks for the input phillip. my thoughts were going in the same direction. just to be safe i'll get a set of genuine o rings and washers etc. in meantime i think i'll change the oil as well . thanks again. pete -)

thanks mate.

you'll most likely have a weepy injector top seal.

I've heard tell of a case of a sticking injector but that also shows up when you read the balance numbers.

the cylinder that has the sticky injector tends to read a low compensation value (theres already fuel getting in)

unless its #5 you can also spot it by pulling the glow plugs.

A field test is to bridge the fuel pump relay, disconnect the ECU or injector harness, then bridge the starter with the glow plugs out. the pot that mists is your culprit.

Ditto the seals.

A dump and refill is a really good idea.
While 'only' 3% fuel, no oil can mitigate against fuel dilution.
It'll be cheap insurance until you get the seals replaced and then do another oil change.

3% is immediate seal replace in my opinion, as a certain amount of that diesel will have already "burnt off", so in effect the bottom end, camshaft lobes, and turbocharger bearings are suffering every time that engine was running. As Rick says change it out again soon but please do the seals ASAP. And only use genuine ones. NOT OEM, Genuine.

again , thanks for all the input. changed the oil this arvo after initial posting . any suggestions on genuine supplier ?? plenty of cheap options , but haven't found any genuine yet. i'll keep looking . thanks again. pete :-)
