All,
I have spent days looking for the right answers for this, sorry if its too basic.
Install is on a 2005 HUmmer H2. LQ4
I have no way to mount the catch can lower than the valve cover ports as I have read needs to be done. Is this a major issue? If the can is higher, won't the oil in the incoming line just run back into the valve cover?
The truck engines have a port on the drivers side that runs directly into the top on the intake. The passenger side has a port that runs into the throttle body. Each pulls vacuum.
I ran the line from the drivers side over to the passenger side and t'eed them together and then ran into the incoming side of the catch can. The out side I ran into the throttle body. I then blocked off the port on top of the manifold. This is a sealed system, no breather. Is this going to work?
Thank you!
Tim

Drivers side should have the Pcv valve on it. It would get plumbed to the catch can, then to the manifold port after the tb. The passenger side should be plumbed to the intake tube or the throttle body fitting if you have it. I believe there's a pretty informative thread in the sticky section on different combinations of catch can Pcv routing.

I assume your talking about sealed catch cans and not cans with breathers on them.
