I un-capped my PCV vent and still have a slight problem


Idle'ing, the car is fine. No smoke.

Driving, same thing. No smoke, under boost or not, and all through the RPM range.

After returning to idle after a drive (or even just revving it), about 30 seconds after idle'ing, it will start billowing blue smoke. Then, 30 seconds later, as suddenly as it started, it goes away and clears right up.


Any suggestions? Turbo/oil rings?

 

Take off the IC piping and check for oil. If there is some, clean it up with a rag, then replace and take for another drive. If it's present afterward, then it's most likely the turbo.
