Message I am coming more to the conclusion that my exhaust leak and smoke are seperate problems so my question is this:

What mechanism or system of the engine would be responsible for possibly dumping oil into the intake side of the turbo(s) after boosting?

After mild to moderate boosting, maybe 4 - 12 PSI, when I let off, the car lets loose a large white/grey/light colored cloud. After driving or letting it idle, the smoke clears itself from the exhaust system and there is no smoke.

The turbos are fine and the motor is fine.

I have ruled out overnight condensation because it happens each time. Each time you can clear the smoke, and each time if you boost it reappears.

There IS a possibility that it is related to my exhaust manifold leak, but I am not positive. I figure there is some valve or line not hooked up properly or maybe broken loose.

What system of the engine would be responsible for doing this? I just dont know. I took the car back to the shop and told them to look at everything and fix it but I want to be able to pinpoint the problem for their sake and for mine of course.

Thanks in advance for the help.
