Logically, you could just put a partial restrictor in that line. That would reduce the quantity of oil that could pass. It would allow fumes to pass as normal. The tree-huggers may prefer that?

If I was going to do it I would put a shut-off in line of the upper vent line. that way I could just shut it off at the track, and back on for normal driving. beats $800 for the track AOS.

Isn't the AOS also there to release crankcase pressure by allowing the venting of mist and separating out its components? Without the AOS to allow the venting, where else would the pressure go?

Probably through the crankshaft oil seals (whistling sound) or up past the piston rings.
Remember the M96 engines have a relatively light piston ring pressure compared to older engines - it wouldn't take much positive crankcase pressure to force them back with not very nice consequences.....

Steven,
I agree with you. And you may get a Check Engine Light/fail Smog?
But I think he mean't just for the Track?
That is why I suggested trying:
