If nothing else is around, even though it's heavy, I've seen the catch cans filled up with old bolts and whatever to condense or collect oil from the blowby mist.
I know about this and was thinking this is the best solution provided you could find the parts in good condition and retrofit them to the early cars. The automatic drain back to the tank is a nice benefit. I just wonder if Porsche made this change on the later cars because they saw increased blowby as a problem on the turbos when they are driven very hard.
