This being HMT and all I think its time to slap together a pump system using an old emissions pump. Anyone do this or know of someone who has? I'm thinking you could get the pump relatively cheap at a junkyard and the rest is all tried and true. The only thing that I don't know about is the vacuum created by these emissions pumps vs. what would be the ideal vacuum for efficient crankcase evacuation.
Hmm...time to do my homework.

make sense?

so doing this ***** way with another pcv valve at the hose going to teh air intake, flipped the opposite way asnormal, will make this work properly? And putting a catch can in-line between that pcv valve and the intake will keep you from sucking all that oil back into the motor (which causes detonation)......right?
I need to do a setup like this very soon. I think crankcase pressure is causing my front and rear main seals to leak...

oil in the cylinders greatly increases chances of knock, boombabba boom. I added a diagram that will hopefully clear some confusion.
