Hello All,

New to the forum, and definitely an amateur in the vehicle world but I know enough to be dangerous and get in trouble. Was installing my oil catch can yesterday....when I realized from all of the other posts I might have done it wrong? I know it goes between the PCV and the intake....but...is this not the PCV in photo 1/1.1? If not what is it and why is it connected to the intake on my CAI (previously the factory intake)? Should I indeed be using the line in photo 2? Are they BOTH PCVs?

I tried to find this on the Google machine, but couldn't find that on any of the diagrams of the various 5.3L Vortecs out there, probably didn't know what to search for.

The blue line in the photo of the driver's side is the correct line. It is the "dirty" side, that has the oil mist from the valve cover going into the intake.

The line you have it connected to on the passenger side is the 'clean' side of the PCV, where clean, fresh air is pulled in.

Are the catch cans directional? Do they have a specific input and output, or doesn't it matter?
