Default AP1 vs AP2 PCV System

As I understand it, AP1s tend to push oil through the PCV and back into the intake during sustained right had turns. I also understand that this isn't a problem due to some revision in the ap2.

What exactly is the difference? Based on the images I can find, the two valve covers look externally identical. Is there a baffle on the inside of the ap2 valve cover?

Anyone know?

The hell it isn't. My car does it like crazy. I've also heard of other newer CR's with the same problem.

I see it at roebling road a lot in turn 3 on ap1's and ap2's

some people say theirs doesn't smoke but they are just not pulling enough G's it takes about 1G round the left hand sweeper and brake reasonably hard into the right hander
