I find your theory about the way such a leak would end up in the engine case interesting, and worhty of consideration.
I did fail to mention that I was having clutch engagement/ disengagement issues over a period of months before my failure happened. Flushing the system of old fluid, and bleeding it "seemed" to cure the problem (had to do 2 or 3 times in those 5 or so months preceeding the failure).
My theory could certainly be flawed, it wouldn't be the first time.
No doubt about it, mineral oil won't be a very good lubricant compared to the recommended Motorex, but for a significant drop in overall lubricity, I think you would need to have more mineral oil go in than seepage amounts. My clutch has mostly been fine though i must admit, recently, on a few occasions it didn't go straight into neutral as it always has...might be a sign. Will dismantle my slave, see what I find and report back.
Did you ever manage to lay your hands on another engine to replace your damaged one?
