I expected to see both oil and water in the catch can but it mostly water. Isn't water in the intake supposed to be a good thing anyway?
I think it just means there is condensation in the catch can, same reason why there is water condensing in the exhaust.
It is not a great system, the 9-5 models have a lot of problems with oil consumption, even after trying to reduce it with oil catch cans draining into the sump. Fixes have been tried drilling out the hole sizes etc.
Part of the trouble is that when there is vacuum in the throttle body, there is a small open line to the nipple, and from there a bigger open line to the intake. So you really can't tell where the vacuum is sucking air from, depending on relative pressure before the turbo, the valve cover, etc.
A second check valve would seem to fix that, but might screw up something else. I don't know how you could figure it out w/o multiple pressure gauges (the industrial kind, not the boost gauge type). And the pressure in the crank case changes with wear on the engine, too.
Not sure about the baffle... If the baffle is at the valve cover, where is the small line?
