D3LSLO,
Ah...I just searched Google for oil catch can...now I see what you're talking about. It seems that this can's purpose is to trap oil and moisture blowby. Heh, never heard of such a thing. Does the tubing come from the PCV system? Uh, depending on where you live, I'll bet that it's against emissions regs to install such as device as the blowby should be vented back into the intake.
So you are getting excessive moisture in there...hmm. Tell me this, before you put that contraption in there, did the car run poorly after an oil change?
