Exotic Performance plus, VRE, Shane at thunder racing, Stenod, all told me I really didn't need a PCV setup b/c it was basically for emissions and I should just use a Pipe plug to plug it up. Here is one of Stenods customer cars they just did and this guy drives this on the street often even with the Glide http://ls1tech.com/forums/showthread...&highlight=PCV
Some peope say, " well you need to change your oil more frequently" and I change mine every 3000 miles regardless.
I still have some things to think about with the PCV setup but I may go with Bret's idea still since it seems like less work and just as Effecient

I like the idea of running the other line off the catch can to inlet side of the blower too. Looks like I'll be changing mine as well.



Man I must have a bad system or something because of all the cars I've owned even new off the show room floor and changing the oil myself I've never seen oil go in clean and come out clean. Not trying to debunk you but I'd love to see that for myself.

Why would you need a check valve if that line never sees boost? In other words your drawing air from the lifter valley and sending it to the suck side of the blower through a catch can.

I suggest you leave the driver side pcv valve and rubber line hooked up as though it were stock(it hooks into the front of the intake manifold for vacuum and draws harmful blowby from the lifter valley on the driver side of the engine).

Then I would run the passenger side breather hose through an air/water separator(check out projecttransam.com for details) to the suck side of the blower. There is a picture at the bottom of my cardomain site.

I've run this setup for 25,000 miles and it works great. Also you don't have to add a catch can to an already overcrowded engine bay. I get about 2 or 3 drops of oil in the separator when I wind it up to 6400 rpm. This is because the blower intake makes a lot of vacuum at high rpm. No oil leaks, no pressure in the crankcase, and I'm running 6000 miles between oil changes.

I have checked mine at full boost by having an assistant hold their finger over it. It doesn't leak. I think if you put an aftermarket check valve you would lower the cfm while in vacuum.

For what it's worth, I just tried one of these and the little plastic bowl is already showing cracks after only driving one day. I tried to mount it over to the side of the engine compartment, but evidently it still gets too hot for this catch can.
