BTW Chuck, how are the Teflon oil seals holding up?

They still look like new after 250 hours. I did not have any more to use
in the current motor so I installed stock O rings. I can reuse the TES O
rings in my next build.

Thanks Chuck.

Back in 1965 those O rings or the lack of them gave
the rotary development engineers at Mazda fits for quite some time until
some genius engineer decided to try them. Nobody at Mazda thought they would work
as they all thought the engine was too hot in that area and O rings would melt.
Prior to that the oil kept leaking into the combustion chamber causing the
engine to smoke. Evidently the engineers were trying to solve the problem using
conventional all metal  piston type oil control rings but they were not working.
