Many manufacturers do include separators, but to make the whole assembly compact and maintenance-free they have to drain the condensate back into the sump. This makes the catch can a part of the engine. And it is not very effective ..., partially because of the heat. This is why external cans collect at least something, the stuff left behind by OEM separator. ...
Good point. Mine seems to work adequately, judging by the very low oil consumption so far.
Not catching a lot of condensed moisture doesn't mean it's "not very effective." Blowby inevitably contains water vapor, and it's harmless in the intake, as long as it's still vapor. The objective of oil separators is to catch the oil and other junk that can make trouble in the intake, not water.
