Dick, I base this claim on the fact that I pay close attention to turbocharged DeLoreans when at large DeLorean events. More than half of the turbocharged cars that I have looked at have some sort of problem where the crankcase is under pressure. In my case, I suspect it is due to a cracked ring. A simple test: With the engine running, remove the breather cap (where you put oil in the car). Does smoke come out? On a regular car the answer would be no (or very little). On many of the turbo cars I look at, smoke pours out and that is at idle! You may be a bit less aggressive of a driver than most of the other Turbo owners, or it may be due to the thin air in the area you live (I am at sea level). Either way, keep an eye out for this when inspecting Turbo DeLoreans.

I, and others, have put many thousands of miles on the PRV engine running anywhere from 6 to 7.5/8 lbs. of boost with no apparent problems. I have personally put over 120,000 miles on twin turbo equipped engines and have had no engine problems. <SNIP>
