is the pcv valve under the fuel rail and goes back into the intake mani on a y8? so to make a catch can do i take the hose from the valve cover to my catch can to the intake part of turbo then wat do i do with the other end of the hose going into the mani ? do i plug this up or can i make a T and run my bov and boost gauge in it?

i read that10 times im confused

 

pcv valve----->catch can------>pre turbo........plug the intake mani where the pcv ran to and slap an air filter on the valve cover then call it a day

 

thanks u helped me a million

 

that's how i have mine set up, and it kind of idles rough. My guess is i don't got enough suck at idle, which, is why i'm assuming others have the 2 way setup that also takes vaccuum from the intake manifold. However, the sticky thread about that doesn't have any pics and i don't know what is going on from the description. Anyone have shots of that kind of setup, because i would like to convert...

 

mine idles fine with the way it's set up

 

i think my lines may be too small, and i still need some tuning

 

JDM, to do that setup you can just use this:



the bottom connects to the black box, or gutted stock pcv.

the one that says pre-turbo intake, hook that up to a catch can, then a pre-turbo intake

then the other one to the check valve, then to the intake mani.

hope this helps

matt.

 

so i run check valves on my catch can piping before the catch can and after the pcv ? i thought i ran check valves on my map sensor on the intake manifold
