I've read through most of that monster HHR thread, and based on observations from my donor, I think the proper way of installing a catch can is hooking it up to the port inside the intake manifold.
From what I remember on mine, I don't recall having any oil in my intake tube or turbo inlet blades which leads me to believe that it doesn't vent in that direction from port 1. On top of that there is a check valve to prevent flow in that direction
I also don't remember seeing any oil in the turbo outlet blades, pre-intercooler pipes, or the intercooler itself. Everything was was pretty clean. If it did flow in that direction, I would think that your intercooler would get covered in oil which would cause problems in itself.
When I removed my intake for valve cleaning, there was oil everywhere. There were small puddles in a couple of spots and the intake runners were definitely covered in oil. It was a complete mess.
You're definitely not hurting anything with the catch can, but I don't think it's going to help as much as you hope. I hope I'm wrong because I'd really like to see a good fix to the carbon build up on these GDI motors.
