PCV set up.
It's not on the car yet because I'm waiting for heads from the machine shop.
Dirty side is a single line running from the passenger side valve cover, to the normal vacuum port with a fixed orifice pcv "valve".
Metal baffled valve covers(passenger side from an ls4, drivers side from a gto).
Clean side is pulling from the throttle body as normal, but with a check valve so nothing can go backwards into the throttle body.
Edit: ignore the random hose on top. That's the hose for the rear of the drivers side valve cover. I didn't cut it yet because I'm waiting until it's on the car.
