Well, people bitched about white gunk in the Crawford AOS before they added the coolant line (mostly folks that live in cold climates), and apparently the new AOS fixes the problem. So I'm guessing that it makes a real difference.

I think the oil passages are pretty similar on all EJ blocks. It's just the heads on the EJ2x7 blocks that get the extra set of breathers to help with high-G oil issues. But if Grimmspeed is specifically admitting an issue when autocrossing and is working on a new revision to their AOS, I'd say that's a pretty good indication there's more than just a hose routing issue.
