Right, thanks for the clarification. I do have the puck. And I was thinking about connecting it to the pipe that runs to my air filter (between the filter and turbo), which has both aluminum and silicone sections. Or, it might actually be easiest to make a hole in my filter canister, which is plastic (again, keeping in mind that it should be after the filter).
It was a rare problem until recently -- I think made worse because I'm running higher boost. After disconnecting my catch can today I drove quite a bit and have not seen oil. It's a shame -- the catch can is a nice, solid aluminum unit, but I think it is at least part of the problem. However, I'll bet if I connect one end of the line to my intake, the vacuum on the intake will more than make up for the restrictions of the can.
Since I haven't been seeing any oil in my catch can, I may run it with a disconnected hose for awhile and see if that fixes it.
