Title: oil in exhaust?
Post by: benmanc on 15 August 2014, 08:18
If my turbo was slightly knackered and leaking some oil...

Could some end up in my exhaust?

It could explain both my slowly disappearing oil, the slight white smoke and the fact my exhaust got quieter a couple of days after putting it on..

Oil burning will be blue/grey smoke and there's no mistaking the smell. White is normally water burning off which can again be your turbo but a small bit is fairly common especially if you have a decat fitted.

Oil can end up in your exhaust if the seals are leaking

Cause for the loopss of oil or the cause for the smoke?

if your rings have gone it smoke massively on startup then calm down once the rings have warmed up but will smoke badly under boost due to cylinder pressures increasing. You'll also see oil coming from everywhere as the crank case pressures will increase

whip an intercooler pipe off, that will tell you if the turbo seals are shot, mine literally pi**ed oil out

lots!!!

that's the lot off hand....

I'm always getting the fault code come up....

         16795 -  Secondary Air Injection System: Incorrect Flow Detected
                  P0411 - 35-00 -   -

but I have deleted everything and put resistors everywhere.... think I need to test resistors make sure they are all working properly  :undecided:

I did notice something on ross tech website about that fault code... Fuel Pump Relay (J17) faulty
so I need to locate these and have them tested too.

what you recon?!!!!

sounds like a few things, id take one of your IC pipes off and see if there is a lot of oil in it (Turbo fault) have you had to top the oil up a lot?
The cutting out all the time I would either say the clutch or the fuel pump.

you running a decat? I can never remember
