My understanding is there is no oil in the compensator , so I would be looking elsewhere - Oil tank lid no screwed down ?
Tank lid was secure. And ...... when engine was running the oil came streaming out of the big hole in the compensator / clutch housing (see picture)
So the only thing I can imagine is a badly leaking crankshaft seal.
Does sound like an engine oil seal or similar, provided all the hoses are still attached correctly, which would be the first thing I'd check.
But yes, engine does have to be split from the gearbox to get to the compensator housing in the middle, so there's plenty of opportunity to disturb something crucial. But I'd check ALL the oil hoses first, as that is simply the most logical and obvious cause. Crank Oil Seals normally leak slowly, not gush like a Texan oil find!
