"I would also surmise that absent the tube, the larger orifice on the drain side of the separator(again w/no narrow drain tube) would then allow the oil to go down via gravity? I cant think of any reason why removing it would alter the functionality....your thoughts?"
Hey Matt,
My first thoughts agreed with yours, but then I got to thinking that if that tube didn't have some purpose, they could have just used a short stub hose or some kind of o-ring.
But it now seems to me that Volvo must have found good reason not to simply leave a hole there, and went to the trouble of the uniquely long, clamped tube.
