I sorta forgot about this issue and BOOST. I would have but just researched the part needed yesterday on theturboforums.com
I had a huge problem with excessive Crank Case Pressure on my Supercharged Dune Buggy Engine. The engine builder did not take this into consideration and when It got to about 10lbs of boost the crank case pressure was so great it would weep oil out all the gaskets and ROB power when slinging oil all over the place in the pan. He had to pull that engine twice and replace every gasket.
