Blue smoke out exhaust at WOT intermittent
Hello,
Just noticed I have blue-ish colored smoke exiting out of my exhaust at wide open throttle sometimes.
The doesnt smoke on start up.
I do premix sometimes, about every 2-3 fill ups 8oz per full tank.
Stock OMP is hooked up
Is it normal for this smoke to be exiting the back of my exhaust?
My mods are
Power FC
DP, MP, Cat back
Non-sequential twins

your obviously burning oil from somewhere
even if you have good compression there is going to be some mixture of the oil in the combusion chamber due to the OMP but it shouldn't be noticeable.
i'd say check your turbos. i even have oil blow by in the intercooler piping but i don't have blue smoke. there should be a negligible amount

Ok
i took the car out again today, and i just wanted to make some changes to my original post.
the smoke is gray smoke... most of the times it will shoot out of im doing hard pulls...
usually i see the smoke almost like it is igniting when i let off the gass after a hard pull. there will sometimes be a trail of greyish smoke.
Could my tail pipe possibly catching on fire?
im running 12 psi on the turbos, they are freshly ported, not new turbos but pretty decent condition

Is it necessary to let the car sit at idle before you shut it off?
i used to do this when i first got my car
then i herd it was unecessary. so i stopped doing it.
I just drive off boost for the last 5 mins before i put away the car.
Letting the car idle and letting oil flow through the turbos and getting all of the oil out of the turbo is really necessary ?
Can someone explain what the exact purpose is when letting the car idle for the turbos?
If i just shut off my car and not let it idle long, and if oil is still inside my turbos or whatever, could this be sorta causing my light trail of smoke out the back of my exhaust once in a while ?

regular driving with a few boost runs...
and then when i am full out driving hard and boosting more often...
is it necessary to get turbo timer to avoid cracking of the turbo housing or manifold?

HAHA... Sorry.
I didn't realize you started that thread, also. So why did you ask the question again?
