I am back to the obvious and most simple conclusion. I'm gonna try the sealant and see what happens.

I may also try packing string similar to what is used on old fashioned plumbing valves.

I found one a suitable size that is good up to 500 degrees f. Do you all agree that 500 degrees should be good 5' from the engine?

Thanks fellows for all the kind assistance and information.
