What he said...what CC is it? I'm looking into making some baffling for my boomba CC. Don't like the probability of some of the oil being sucked up.
Mine was made from an M7 system designed for a Mini Cooper.
I had a new one laying around so I used it.
The can is very similar to Mishimoto's basic black can.
With the can in the closed PCV system as mine is, baffling does not work.
If you allow the can to fill, the fluid can always get sucked up.
The only way to prevent this is to have a vent.
However, then you don't have a closed system and the PCV doesn't work correctly.
The best way to keep fluid from getting back is to just drain the can frequently.
