Ok got my T2 S4 new motor installed and fired up, and have Excessive oil smoke from the exhaust while idleing.. should I be worried or should this go away? or should I call the builder and tell them whats going on. the last motor did not smoke this bad on first fire up.. Perhaps did I use the wrong Viscosity oil ( 10-40) should I move Up to 20 W 50 instead.. Can some one shed some light on the subject.

 

A brand new engine when first fired up will smoke for a few minutes. If it has been more than 15-30minutes and it is still smoking something is wrong... Possible turbo leaking oil or worse would be improperly built engine...

Call your engine builder. Oil viscosity will not make a new engine smoke after it's initial startup.

 

yea im having the same issue , but im like 99% sure my turbo is blowndiggity
