I decided to make some washers out of leather and some out of gasket material...this gave me the opportunity to buy a hollow punch set from HF. I used an old split leather belt for the leather washers and soaked them in oil. I used standard sheet gasket material for the other seals. I installed the gasket material first and tightened the nut and left it while the leather ones soaked in oil. When I pulled the first gasket it was shredded, much to my surprise. The leather gasket fared much better, compressed, sealed, and didn't tear. The proof will be a leak free oil pressure gauge once the engine is installed and running.
