I think you just like being complicated.

seemed like it was working ok but you definately need a way for presure to get out if that unit doesn't work well. i pulled it off for some reason toward the end of when i had my truck and i couldn't tell the diference. ended up running just a filter on the valve cover and the same set up on the fairmont.

the fairmont has seen a pretty tuff life and that filter is barely damp.

OK sounds like maybe it's not worth the hassle then. I could put a line from one of the valve covers to the elbow in front of the turbo with a catch can inline a lot easier than installing that scavenger kit. Thanks for the update Jim.

you will get oil into your intake track with that method. oil in your intercooler and burnt oil in the chambers.

i know you dont want to just vent it but i think that is the best way to do it. simple, cheap and efective.

I have mine jest vented...don't see any reason to go any other way just yet, I might put a vacuum pump on it at some point but not doing the oil injesting that I was doing before.

Venting does not pull out the fumes that accumulate in the crankcase...I want at least one suction point that will circulate fresh air through the engine.

there are negatives to each solution. either your oil gets dirty a little faster than normal or you have oil in your charge pipes, intercooler and combustion chamber.

for me it is about cost and performance. the vent cost the least and will not have a negative effect of performance where the oil in the intake probably will.

While reading this i remembered that i still have those Solnoids from the STS kit..
Im thinking about running the 'noid to the Hobb switch so it can pull vacuum on the Crankcase until i get in boost then it opens up and lets the CC breath to the atmosphere through a breather. also run a catch can so no oil should go into the intake?

Sound good?
