I use these on the rear main bolts on my original engines and I think I have them under the external mains castle nuts too from memory.
Are these what Dennis and John are referring to?
My Dowty washer kits have a stiffer Shore A 80 Buna N than standard O rings for better sealing in this application .

The leak I’ve experienced usually in a similar situation was around of from the threads. I’ve never seen brand name, what was called a Dowty washer. They might differ from what is available here. The conversation I’ve had with Terry was his concern that original Model A engines did not have washers under the nuts. We do what we have to stop the leaks.
