Paul,
I am doing some research for a mate who is developing his own engine.
Can't comment further on this, other than it's a rotary - don't hold your
 breath !!!

I have offered to help and he has asked me to research seal material
ie. he wants to make his own seals by using some pourable material
that can withstand a high temperature - about 250 Degree C.

Can you or the boys over there offer any suggestions. My first thought
was a Devcon product - Flexane, but the temperature resistance is
low.
TIA

Teflon is the only plastic that I know will hold up at those temps.
I have no idea how you would cast it. Machine it yes.
Red RTV might work as long as there is no gasoline involved.
Perhaps JB Weld. They claim 600 degrees F.
