I am wonerding if my twins are shot. Basically this is what is happening. I recently switched over to a full non-sequential setup. The car boosts fine. Spools quickly and holds boost as long as i ask it to. The problem comes when i let off the gas after a boost run. I get alot of white/blue smoke from the exhaust and i get the smell of oil. Like i said this is only after i let off the accelerator after boosting hard. Is this a symptom of possibly a leaky seal or something in the turbos. I cant figure it out but i am fairly concerned and try not to drive the car under boost until i figure it out. Alittle background, the car has about 48K miles on it, so maybe the turbos are showing there age? Any help is greatly appreciated.

 

I'm guessing turbos. Is there oil also in your intake tract? Can you produce any axial play in the turbo when the inlet elbows are off?

I have always noticed oil in the intake tract, even when i purchased the car with about 35K on it, but there was never any smoking or oil smell like i have now. When I had the turbos off for the non-squential conversion, i didnt notice much if any play at all. Man i hate the thought of pulling the turbos back off for replacement. Guess this is my sign to go ahead and get that GT35R kit Ive been drooling over. Hahahaha.

 

From my knowledge there is always a slight glaze of oil in the intake tract. If you're going to check for excessive amounts check your intercooler as the endtanks are a common place for oil to accumulate if there is excessive amounts in your intake tract.
