Spitting Unburnt Oil Out The Exhaust

[Primordial]

I noticed that when I started my car today that a lot of oil got spat out, and it left a 60cm x 30cm oil patch behind the exhaust. It then proceeded to burn a lot of oil as there was a lot of black smoke coming out.

I got hesitation all the way through the rev range until the engine had warmed up and then it has been fine ever since... No more burning oil, no more oil ejaculations

I am not sure why this would have happened. Does anyone have any ideas on what may have caused it?

The only thing I can think of is that a mate was pumping the accelerator while the engine was off the night before. Is there some way that this may have caused it?

Thanks for your help!

are you sure its oil and not fuel?

[Primordial]

definite... it looks like oil (black)... it smells like oil (bad)... feel like oil (oily!).. and it stains like oil (bastard!)

if its definitely oil then your turbo is fecked mate... i'd suggest it'd be a combination of moisture in the exhaust and fuel, and it looks black due to the carbon build up through the exhaust system.

aaahh I think you may be right! good thinking!

thanks mate!

(wishfully thinking that its actually moisture not oil!)

Do you have std ecu or aftermarket?

I have an aftermarket ecu and my cold start requires to be retuned, booked in for next week. Sounds like mine, has to much fuel that will foul up the plugs if not driven once started. You get a 30cm trail of black crap behind the exhaust. Once warm the ecu switches out of "cold start-up" and performs fine. Nothing to worry about, just get the cold start tune rechecked.

yeah i've got a PowerFC

i'll get the cold start checked. thanks mate!

Black smoke=fuel, blue smoke is oil .

[Primordial]

Yeah i seemed to think that was the case.. I wasnt too sure though.

thats a relief!!

Most likely condensation + carbon build up
