Bump again.....
I wanted to elaborate more on my question:
After a track session for 20-30 minutes of high boost driving at a DE, I really notice the smoking upon startup. Basically the car smokes very badly at idle until about 3-4 minutes pass beofre it clears out.
Plus I use alot of oil, probably on the order of 1 quart every 40 track miles which to me is ridicul;ously excessive.
Can anyone say that the pcv system as designed in the earlier cars before the addition of the separator in the 86 models is the main culprit of all these oil in the intake manifold? Are turbos more susceptible to blow by issues than N/A cars, especially when run hard under high boost for extended times like a track event?
The car runs fine otherwise and does not burn such amounts of oil in street driving.....that is what perplexes me now.
