Well. Tightened up the other 3 trans bolts, shot the underside with carb cleaner, started and warmed the motor. Can't see any oil leaks Wtf! Clutch feels normal and with the top two and rear 12mm bolts tight, I can't pry the trans away from block in the front.
So I think I'm going to push my luck and run it at island one last time with the front trans bt missing. Who knows, block could have been cracked & disconnected for a while now and I just found it. So long as I check the remaining three bolts every pass and it's not pumping oil out, I should be ok to make one more track day.
I'll figure out a permanant fix, likely pull motor & get it welded then put it back in. Maybe with a bigger turbo in the 60lb/min range.
