Coates engine already passed the EPA tests, therefore I doubt there any validity to the exhaust valve concern, plus he has water running thru the shaft of the valves to keep them cool. Most likely Coates uses a special compound on the seals that does not expand with heat and is durable. I am sure we will eventually find out what keeps the engine working.
