You are going to hear a lot of different methods for routing your PCV.
One thing is for sure You do not want your bottom end to see boost, you can damage your main seal, that is why we disconnect the PCV system.
The valvecover is connected to the intake from the factory b/c it draws in air, but after our cars are boosted it forces air out, this is not healthy for the motor to vent properly.
I have been too lazy to research how factory turbocharged cars have their PCV set up. :P

 

so what is wrong with just venting the VC and Black box to a catch can? this seems to be very simple, what i dont understand is all the complicated set-ups

 

Dumb question:

What is a catch can for?
And what does it do?? catch oil??

Im confused

 

That's what I do, I have my VC go to a Gatorade bottle with a brass barb in the cap with a breather filter on it for catch can. Then from the charcoal box I have another Gatorade bottle. They seem to work fine for me.

 

ive tried setups with the preturbo intake for vac in boost and found it makes almost none. u will get some junk in the tank regaurdless. i also thought of the using one way valves so it still gets vac at idle like stock but i was told its pointless?

ive always wanted to see how stock turbo cars have there pcv system, anyone know?

 

i like the idea of using the power steering resevior. that would be stealthy.

 

I'm confused as well. This is what I'm using currently, and I'm just running one line to the black box, and the other to the valve cover. I'm in the process of having another set up built, and this is one thing that I have heard several different opinions on. I'm planning on running a lot of boost on this motor, so what do I need to do? I bought another catch can, but it pretty much looks like it does the same thing as this does.
