If you've got good ring sealing, thats all you need.
Shouldn't have any oil coming out of the crankcase vent. Last time I did with my M20 was with blown up ring lands. Perhaps the M30 runs a little looser though.
15k or so of somewhat hard use with a blower and it doesn't leave spots or track back on the floor pan from the tube, almost 30k miles on engine build

this might be a silly question but can u run open catch can if u still run motronic? i thought i read somewhere about having crankcase vent related idle issues but i might be mistaken
The crankcase is only a potential air leak with the stock crank breather configuration. If you run it to atmosphere all you have to do is cap off the port on the intake that it used to be attached to.
You have to do this when you add boost so you don't boost the crankcase.
