Nuekin- I completely disagree. It should be routed just like stock... Just like the picture you were referring to except it needs to route back to the intake (pre turbo) to actually relieve crankcase pressure. The idea is to create vaccuum.

Simply 'catches' the shit you wouldnt want going back to your intake, that's the whole point, to keep the system functional and putting in the catch can to keep pipes oil free. Breather filter doesn't cut it because it doesn't release enough pressure or create any vaccuum or pull - thus not allowing the crankcase pressure out of the head/block. Low pressure on the bottom side of the piston is Good, allowing the piston to be pushed down/turn crank easier. No intake vaccuum = positive crank pressure which can lead to a bunch of shitty problem
