Well there aren't too many places it can come from. If the 2T remote reservoir is full, and the plumbing is all dry, the only thing left is the pump. Maybe the O-ring(s) under the pump aren't doing their job? (Later MC21 and all MC28s have two O-rings.)

Is the transmission breather hose intact? Is the end wet? Are you sure it's not transmission oil that's been pumped out?

I'll have another good look around in the morning. Its been sat on the bench a good 2 months without breathing a beat so....If I remember right the oil pump is lower down (in gravity terms) than the rc and exhaust outlet.
Prob a combination of two issues, over oiling on initial start up (for safety sake) spitting out of the exhaust outlet and leaving the RC coated... and an oil leak from the pump onto the bench.

Will keep you updated and thanks for all the effort 👍
