Very crude drawings... Art isnt a strong point
These are what Im doing. Probably the second one. On the second one, you wont need a can on the valvecover to intake line because itll only see vacume at part throttle or idle and as soon as boost is entered, the check valve will close.
yeah but on the second one front the front port on the pass v cover it gos like into a y then into the can?

This is what I gatherd from this, Plumb it on the intake side of the turbo, Then place a breather/ catch can in line with that, then put a check valve in with the intake hose to prevent crank pressure?????
There are 2 ports on the pass. valvecover. Ill use one of them to tie to the LS6 cover port (Y junction) and then to the can and to the intake side of the turbo. Then the other port on the pass. valve cover to a check valve (you need a valve becuase boost will be pushed into the case if not) to the intake port for vacuum at idle. Its 2 different routings.

Yeah, its a lot easier to understand something when is in a picture. I imaging that you dont need the filer on the drivers side, but itll allow a way out if you cant create enough vacuum and the case starts to build pressure.
well they are center bolt covers i bought for my set of lq9 heads.right now the motor is still all 98 stuff bone stock,i will swap the heads an ls6 cam etc. by the end of the year just gathering all info all can
i know some of them do bring 2 ports but some only bring one.seens it only brings one can i do ur first pic setup?i know the second pic setup is better though,also what filter do u run on the driver cover?
Whatever happened to running lines from the valve covers to the header collectors?...like we did "back in the day"...which BTW, was a Wednesday...
It worked fine and the exhaust damn sure caused a vacuum to help pull it out...
Even if you still had cats and/or rear o2's, you could tap beyond them...but I don't think that applies to most of you guys...

the exhaust is also doable, but you cant just plumb into it. Theres a "special" venturi type fitting that the supra guys use to do this. I havent seen much feedback on it. I could see with our oil in the PCV being an issue of smoking though. A catch can helps but it isnt the end all.
