Upgrades and improvements for longevity

[AustinWood]

Once again this is an application where compression of the gasket causes problems. The gasket will compress around the bolts which reduces the pressure on the space between the bolts. It also causes the sheet steel sump to become distorted and aggravate the problem. Further tightening the bolts then makes it worse not better and leads to stripped studs.
Some crankcases have blind holes for the sump bolts. If these have dirt in them the bolt will bottom in the hole and then snap with very little torque. Make sure the blind holes are clean.
