I ask this because if you have then you might not have noticed that there is a restricter. That allows the air but because of the size, it usually does a decent job blocking the oil. Obviously it still lets some through. But just a heads up. First picture posted is of the restricter.

The second picture is of my setup, which is exhaust evac. Mainly you use the power of the exhaust flow to increase the vacuum siphon in the crankcase and head.
