I appologise for asking the question again, I understand there may be a chance it's to do with the injectors but no one else seems to have had this problem which is confusing me. All the people had their sump levels increase. I am checking the oil level after every time I run the engine which I dont at the moment. Please dont read any thing in my questions but I need to eliminate as much as possible due to no funds to pay a garage to strip engine. All my spare money went in to buy the truck. Many thanks to all for your help and support and sorry again for being a pain. Regards Smile

the only places it can mix are the head if it's gone porous the sleeves if the seals are on the way out, the injectors, or at a push the high pressure pump.
they are all quite expensive though so are you sure it's oil and not just dirt from the tank?

I have decided to strip down and check injector seals as it defintly looks and smells like oil. If I remove the injectors can I buy just the 'O'rings as a kit? As the injectors were done on recall I am hopeing they are ok, if so will they need a tech2 or can I just refit them? I did a head gasket change on my old E reg petrol trooper so hopefully this shouldnt be too bad! To check the sleeves can this be done with the head in situ and can I replace just the seals? Will the problem be easy to see once injectors are removed? Do the seal split or just flatten? Sorry for all the questions but the more knoledge the better. Thanks guy's.

Thanks for info. Where is best place to buy seals from please? Are there any other problems which can occur durring injector remoal etc? When refitting do you lubricate the seals with any thing special or just some lite oil?

only get the seals from a dealer as they will be the latest ones. no problems with removing the injectors and just smear the new o rings with some oil

Sorry also meant to ask, if I need to change sleeve rings are the pullers expensive or can I make something to remove them?

Had sample of fuel tested at lab and it is definitly oil. Tha oil level on dipstick has gone down very slightly. Have taken car to garage as found out the injectors had been done last year but not sleeves/seals. I spoke to the engineer who has dealt with alot of these problems but has not come across oil in fuel. They are going to do the outstanding recall work and also check the injectors. i think the fuel/oil pump units are very reliable as I cant find any one having any probs with these. The only thing left could be the seal inside the injector on the popet valve alowing a small amount of high pressure oil into lower pressure fuel. Oh well hopefully they will find the problem. Many thanks for every ones help so far. I will let you know how things go.

Regards
