Quote: 625 hp that's more race than street, you will get the vaccum pump when you get tired of fight the oil leaks and if your getting that much crankcase pressure your rings are not seating. vaccum pump probly pick up 40 HP on your deal
I am ignorant about what a vacuum pump actually does...even after reading over the website you posted in your original response. Actually, I'm ignorant about why there is excessive pressure in the crankcase. Is it a sign of a poorly built engine or a tightly built engine?
