turbo passing oil

[andz327]

Diesel doesn't go near the turbo,
Slack injectors will blow fuel past their compression seal(copper washer) straight into the cam box
Could be faulty injector over fueling
Possibly hole in a piston

this wouldn't explain why my intercooler, inlet and pipework was full of diesel/oil though would it?

If your oil level is above max forever reason it will blow out the breather into the intercooler.

[andz327]

Is there Loads of oil around base of injectors??

Thought the light came on at 18k if its 20k then it's every 20k she gets serviced

ANDZ

Probably is every 18k, I meant 20k ish in general. I just thought you had shorter intervals because it made it to such a high mileage.

Nope when servicecomes on dash, if i done every 5k like someI'd be doing an oil change every 7 days when I'm busy, quality oil keeps her happy

Not looked. I’ve only just replaced the injector seals.

[andz327]

Maybe thats where the fault is , injectors not seat properly and the blow by has dieseled yer oil making it mega thin and pissin through your turbo and like Bambi said if its put oil level way up then it'll be blowing into the breather also, i take it you used new bolts and the newer clamps and recut the seat

Do you think? Yes new clamps, bolts, copper sealing washers and seats recut. Would it not pass up through the rocker cover around the injectors if it was that?

As the other chaps have mentioned, oil can only get into the inlet side of things via turbo and/or breather system. Fuel in oil can only come from injectors with poorly seals, or duff piston/rings, have heard of pumps with poor drive shaft seals leaking into the timing cover... but this is very rare.

There's room between the copper seals and rocker cover seals, if the copper seals are not perfect and clamps are not holding well, fuel can get between the seals and eventually end up in the sump, hence all the fuel in your oil.

Seems possible! Would this be enough to over fill the sump and cause runaway?

Unlikely, unless the oil level gets to the level of the breather line...which is again, highly unlikely. I believe it's your turbo leaking oil, filling the intercooler and hence the air intake system with oil, which is causing the runaway. There's hundreds of examples on boobtoob.

The oil has to get to the inlet manifold before the engine can run on the oil....The engine has to be a horrendously heavy breather if the turbo is ok and it's filling the intercooler/intake with oil.

Checked breather and return pipe today and both clear. I’m thinking compression test next. Any other ideas? There defiantly something causing oil to get into the inlet. My intercooler and pipe work was full of oil also pipe work from and to the EGR.

This definitely sounds like the turbo has a problem, with the amount of oil in the pipes, intercooler ect there not many places the oil can come from.

We had a Renault migraine that the turbo went on, it didn't run away just smoked like a bitch and kept overheating, new turbo and all way fine, for 2 weeks then it popped a piston

I dropped the oil today and there is masses amount of diesel in there! would this indicate anything or would this still happen if the turbo was at fault?

I would be checking the high pressure diesel pump seal

[Patvan247]

where is this seal located? I replaced the SCV not long ago due to idling issues.
