Gen IV ECU running 496 - PCV system routing question Mine is a bit of an oddball, the truck is a 2008 suburban HD but the factory LY6 has been removed and a L18 sits in its place. I'm sucking up a lot of oil in my catch can but I believe it to be related to the valve cover baffling for the pcv system but I want to double check my routing to see if it makes sense.
I am using a closed system, this mimics the LY6 setup as I have no valley port available and I added barb hose fittings to the valve covers so I can plumb a catch can setup. Normally there is just a port on the bottom of the intake manifold sucking up the valley oily air but that port has been plugged. The port on the intake back is only 3/8s" though - should this be 1/2" like the other orifices?
