Thanks Ruairidh,
I've tried shimming the bell housing out from the crankcase. Doesn't seem to have made any difference, which rules out the spigot being too long and bottoming out. I can spin the input shaft around with the lid off the box and clutch depressed, and the driven plate seems to turn freely. I wonder whether the crank/flywheel nut/washer is fouling the boss. It must be something that has enough friction to spin the input shaft when the oil is hot. Could be that the driven plate is not fully disengaging and still rubbing on either the front or rear linings. I've always used gear oil, and I would think that engine oil will only make the situation worse..
best,
Nick
