<< - how to how to seal the leak (what to use?)
If it will fit the recess in the case, buy a 5/8" flange head cap screw to
replace your ersatz drain plug.  Or have the seat of the plug you now have faced
off on an engine lathe.

- where to get 0.650" ID X ~0.865 OD hollow crush washers?
Sort through the stock at an auto supply house.  Check with a BMW bike shop,
Beemers are festooned with crush washers.

An o-ring would work if the head of the fastener has an o-ring recess cut
into it.  As a matter of fact, sealing cap screws with o-ringed heads are
manufactured and available but at no small cost.
