How are LQ4's pcv system set up?

Hey Nick--been going between this thread and the other on on Tech...and this is what you need to do:

Here I talk about leaving the passenger side valve cover connected to the nipple on the TB...

Now--you could actually LEAVE the passenger side tube from the valve cover to the TB alone...

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.

I explained this here KINDA...but since you are running a car style intake versus a truck style, the PCV port into the intake is different. On the truck, it is on the top. On the car, it is up at the front on the passenger side behind the TB.

This would leave the driver's side valve cover hose to the inlet of the Catch Can...and the outlet back to the top of the intake where the PCV actually is...

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.

ALSO--that oil/water separator thing you are using for a Catch Can is not gunna work and is not a real Catch Can. Sorry to say...but you will be blowing-by it all of the time and it will fill up in a few days. Go ahead and get a Catch Can from Saikou Michi, AMW, or RevXtreme.
