I wouldnt, there is no point unless you have the LS6 valley cover. Like I said go buy 4 feet of 3/8"s fuel line, a plastic t fitting, truck pcv valve and dual catch cans and you are all set

deleted the PCV system and now i am running a breather on the front of passanger side valve cover and a breather on the rear of driverside valve cover. Cant help but notice that the breathers expell a slight bit of smoke and soot... other guys with breathers does your engine bay get really dirty from running with breathers?
But I also have a single hose running from my passengers valve cover to my vacuum port on my intake. The TB port is capped off.
I have a needle valve right before my PCV valve in that single hose that I have turned way down, so it sucked just the perfect amount of crankcase gasses, but not too much, I don't get a drop of oil into my intake.
My experience playing around with different combos....the LS6 valley cover I have is GARBAGE. If I hook my vacuum line to that port with the PCV valve in line, oil flys through it like a Chinese bullet train. It pulls the oil mist right out of the crankcase.
The normal way vacuum is pulled without a valley cover, from the factory, is way to strong....the needle valve is perfect to turn down that vacuum force. Factory pull is way too much, its unecessary. If I put a cigarette near my filter on my drivers side valve cover, the smoke gets slightly sucked in so I know I have fresh air crossing my entire engine and getting pulled into the intake. But I have zero oil going through.
I don't have a picture yet with my needle valve and my valley cover port filter......but you can see what I have and what my final set up looks like.

ok so the PCV Is going back in and i have an idea of how i want to set it up... quick question i am getting alot of water in my exhaust like noticeable spray on the concrete where the exhaust exits. could all this water in my exhaust be because i don't have a pcv setup and moisture is getting into my motor (especially as it gets dark and colder at night)? i haven't driven this car but once since the cam install but i have let it idle up to temp a few times.
i will eventually run a leak down test if ya'll think it could be a blown head gasket or cracked head. Im hope'n its just moisture in the oil

If you have allot of water shooting out the exhaust you will simply see the coolant lever drop over a few days time......if its a blown head gasket.
Sometimes I get water shoot out of the exhaust pipes because moisture has accumulated inside the exhaust system over night......

ran a cooling system pressure test today. pumped it up to 16 LBS and waited 30 min. after 30min it was at 15.5 LBS (i think the fitting on the pump was leaking a tiny bit). so looks like no head gasket or cracked head issue... Guess it was just condensation. also i got the PCV back on. Good to go

A vacuum pump will keep the oil out of your combustion chambers, help your rings seal better, and make more power. www.gzmotorsports.com

A good write-up here:
http://en.wikipedia.org/wiki/Crankca...ilation_system
Back in the 50's road draft tubes (in lieu of PCV) were what was used.
