I remembered seeing a post on several different theories about how to re-route the pcv system on a supercharged engine. Someone mentioned the name of a company that makes a special pcv valve that's good for use with superchargers. It has a ball in it to stop the boost from coming back through into the crankcase. Now I can't seem to find that post. Can anybody help me find that company or the even the post?

 

All PCV valves work that way.

 

Yes, but the one discussed in the post I had read was supposed to be better for boosted applications.

That was it exactly!! Thanks maniacc!! :hail:

 

theres another route you can go, the same way i went... It comes in a "kit" you weld 2 things inside the headers and connect a line to your "breather" thus as exhaust goes by this tube it sucks on your crankcrase. the more exhaust your engine makes, the more ventilation your crankcase gets. this solves 2 problems: "bad air" no longer enters the intake manifold. #2: engine rpm sensitive. at WOT you get alot of evacuation, and thats when you need it most, and thats also when your intake charge needs the most amount of density. bah, it made a big difference for me, but not like you would expect. before i rebuilt the engine, I would find water under my valve covers. this was when i was using just breathers, and the water would heat up and turn to steam and clog my breathers... it was a mess. somhow, the water would come through the breather and condense when it got under my valve covers. going to this evac. system fixed that too....
