But that can cause build up in the turbo, piping and the FMIC. The Magnus SMIM should have 4 ports on it, I'm sure one of them can be used for the PCV.  Get a vacuum block or t-fitting if you need more.
I run the Jaz mini catch can/breather and it works fine with the stock PCV.

Not picking on you but the vent on the side sees lots of vacuum when the turbo is spooling. Thats when the engine needs vacuum under boost. When it is at idle (off boost) for example, is when it doesn't see much vacuum however that when the PVC valve works and is sucking air out.
The other reason that it is routed into the intake line is because it needs metered air.
So the people that have vents on the side of their valve cover are also pulling in unmetered air through the PVC system. Kind of like what I am dealing with using a GM MAFT
