Hi Drew,
Yes I did read your experience, so it's on my list of 'not to forgets' - I just can't remember where i put that list !
Engine casings should be back with me by the end of the week, and they have that plug and other threaded oil gallery plugs in place, so I'll make sure to remove them all and give everything a good wash and blow.
Just ordered some Threebond for the re-assembly - did you use any on the oil seal outer surface, or leave them dry ?
