Hi all,
As per the photo my crankcase has numerous small voids in the surface that will mate with the sump, some very close to the threads.
My intention is the lap both the base of the crankcase and the new semi-deep sump to make that connection as water-tight as possible. My theory is that the better I make that surface the less work the gasket/gasket paste needs to do and thus the chances of oil leaks are reduced.
My thought was to clean out those little voids with thinners and then fill them with some sort of quick metal before I lap the surface.
Is this course of action ok and if so did anyone have any suggestions on types of fillers that might suit this application given that the crankcase is an old alloy?
