could detonation blow a water seal?

Well thats what I meant.

Between the water passage and the combustion chamber we have only this water seal. Yes there should be a good seal fomred by the side and rotor housing, and this seal will only be exposed in very very tiny places. But I still think it could be damaged by extremely high pressure.

What a good discussion so far!:D

Ah ok, I got you now. I didn\'t realise the seals were exposed anywhere under normal operating conditions. I suppose that\'s why the yanks are experimenting with all kinds of strange materials for the water seals. Weren\'t Rotary Aviation offering some kind of uprated water seals?

Looks like the stock seals are just rubber. A few companies are offering these up-rated teflon relacements. Notice the stainless steel seal protectors, I wonder if they\'re any good?

The Mazda seals also come with the steel inserts. Well, they did on all the times I\'ve rebuilt engines. I think the Hayes ones might be better being stainless steel.
