Having just acquired yet another good crankcase with all threads sound, front lip intact and no cracks but it had been sandblasted and left for a few years. After removing all the oilway plugs I spent an hour with a pressure washer and washed a pile of sand out of it. This revealed enough sand for a play pit and the top face was heavily fretted at the front and rear nearside corners which is why a lot of Sevens leak at this joint. By the time I'd trued the face up the number had almost. disappeared.
