My plan was to simply splice the catch can in between the valve cover and manifold. The BMS can fits on the strut brace behind the PS fluid reservoir:

Ayyyyyyye, this is my video lol.

This. I pulled my intake manifold off to troubleshoot a misfire. There was like 10 ounces of oil in the manifold and the DISA valves were covered, and one was actually broken(due to oil, I'm guessing).
After that realization I vented to atmosphere. There is a little valley going to the bottom of the car right by where my catch can was installed. Put a little KN filter at the end of the hose and closed off everything else.
The N52 engine doesn't created much vacuum anyway and with the supercharger kit, it produces absolutely none where the hose was connected. ( I checked with a vacuum gauge) It does create a small amount of vacuum at the manifold, but not pre supercharger. So I figured it was useless to have it go back into the intake system. Haven't had any problems yet.

Do you have pictures of your setup? I'm currently looking at what to use to close off holes in the intake aswell as probably removing the pcv heater idk if to leave it disconnected
