Upgrades and improvements for longevity

[Colin Wilks]

Thanks Ruairidh. I was thinking that the needs for jointing the block to crankcase and the crankcase to sump are somewhat different, the sump needing to come off regularly, but the block to crankcase joint benefiting from every bit of rigidity that can be mustered, and hopefully not requiring disassembly very often. I am planning a rebuild this winter and thinking that silicone sheet for the sump, but TB1184 for the block/crankcase joint may be the way to go.
