I have a small K&N filter for my oil tank vent...with no catch can, and have yet to see any oil get sloshed or blown out.... I say rip it out of there......
Actually, I would not recommend taking the oil separator out. Oil separators are an invaluable device in any dry sump system. The 930's have two dry sump systems, one in the engine crankcase and the other at the turbo sump. There are times when these pumps may be scavenging a little air with the oil. These separators separate the oil and air, return the oil to the tank, while the air is vented in front of the air cleaner. If you just run a vent line to the air cleaner from the oil tank, you are going to be sucking in oil vapors into the engine. BTDT. Any oil vapor in the intake mixture, effectively reduces the octane level of the gasoline suspended in the mixture AND that is definitely NOT GOOD.
Can you say detonation?
