How are LQ4's pcv system set up?

Nevermind, I saw your diagram when I went home on lunch break. I couldn't see it on my phone earlier because the screen is so small haha

I appreciate all of your help guys! And I ordered a revxtreme can on my break too lol

...leaving the passenger side valve cover connected to the nipple on the TB...

Then take a hose from the driver's side valve cover to the inlet side of the Catch Can, then a hose from the outlet of the Catch Can to the passenger side of the intake...

And since you have the emissions crap taken out, just plug the brass nipple on the driver's side of the intake behind the TB. That should get you the correct routing.

'clean' and 'dirty' are non-technical names for the two sides of the PCV system. Clean (air)= System Input, Dirty (air)= System output


The clean side connects at the throttle body and valve cover for a N/A LSx. This side is designed to flow fresh filtered air from the air intake (atmosphere) into the engine crankcase.

The dirty side connects from the valley cover or opposing valve cover to the intake manifold plenum chamber (engine vacuum).

Blowby can flow out the clean side when dirty side flow is insufficient to overcome blowby production...

+1 on getting a better catch can.

Thanks for linking the diagram Jay. It illustrates what I was saying. Sometimes a picture does better than my retardedly elaborate/confusing verbage.

Yeah--adding an inline PCV would be the thing to do. And the Revxtreme Catch Can is a great purchase!
