Well Ben at GT said they ran it on the dyno for over 60 seconds making load at highish RPM and they didn't see the problem, but then again, I don't get the problem on the first lap either.....
Which leads me to believe that there is a lot of oil in there, just not enough to make it come out on the dyno and that combined with the G's make it come out, because I have NA cam covers, smaller than the turbo ones, it's not helping.
So yeah, next stop is GTR cam covers, then after that we'll have to revise the oil restricters. No one seems to know what's in there, some say Tomei, some say stock. Who knows?! Either way, I'm tempted to just rip the head off and check to be sure.
