I now have a nicely machined replacement crank. Crank case measures within 1thou for c/m alignment (with block&head bolted on). So the engine is now going back together.
I have a concern over using an oil pump cover plate gasket though. There was one fitted originally, but it was torn by the rotation of the pump and it's vanes. This leads to excessive clearance and high likelyhood of gasket material being pumped through the engine - which is far from ideal and will also mean high internal pump leakage and low pressure/flow output. I consider it probably better to not fit a gasket here as the surface and are good and very flat and will seal well. What's the collected view on leaving the gasket out?
