Pat,
That is affirmative. Blow by pressurizes the crankcase, sort of like that atificially provided by rotating the prop to burp the engine before checking the oil.
Normal operations the breather tube attached to the top of the oil tank just below the filler pipe vents blow-by overboard. The oil filler cap has a spring/disk that serves as a calibrated pressure relief to limit crankcase/oil tank pressure.

Yes.
There is no crank case breather for a 912. The oils sump acts as the breather.
