Mid rebuild and I have this crazy idea for the coolant seals on the rotor housings. Im thinking about replacing the rubber ones for copper. I know crazy right? I have access to the tools and materials for the construction of them but how well does anyone think they will work? Wouldn't it be basically the same as copper head gaskets in performance piston engines? Any input would be greatly appreciated.

The only problem with that is copper head gaskets do not seal very well at all unless one of the deck surfaces is O-ringed, and even then they are typically not very good.



They're great at maintaining shape where a composition gasket might blow out. This is not an issue we have.
