I cleaned all the oil that had been seeping out from under the intake, got everything bone dry, and drove it around 300 miles yesterday. And it was bone dry afterwards as well. I think whatever oil breather burp happened at MM while I was thrashing it hard just got oil in that area which was just slowly working its way back out. Not what appeared to be a new oil leak under the intake somewhere.
I have two breathers routed directly into the foam air filter on the turbo - the passenger side valve cover and the turbo drain sump. The turbo sits on the wrong side of the collector and the wastegates and it seemed... difficult to get a proper gravity drain back into the motor. So I put a 1L drain underneath the turbo , drain line going through a hole in the inner fender, it's mounted in the area in front of the passenger tire. And then an oil scavenger pump that drains that tank and pumps it back up to the passenger side valve cover (replacement oil cap with a fitting on it). I'm just triggering the pump along with the fuel pump from MS. The tank has two larger fittings, one for the drain, one for the breather (to make sure no pressure builds up in there) freely venting up to the air filter, and the smaller line to the scavenge pump.
I guess one of the two burped out a cup or two of oil at some point at MM. On Thursday, when I drove Cherohala (fairly gently), Tail of the Dragon (pretty damn hard) and I was also blasting along Charlie's Creek (near the Lodge) pretty hard in spots. Hard to say which breather did it, at this point. Got there, opened the hood, and there was oil splattered all around that area.
I guess I could temporarily route the breathers to separate catch bottles and thrash it around and see if I could get it to burp again, see which one it's coming from. And I probably need to add a catch can and route both breathers to it, then from there to the air filter.
