Leaking powervalves at gaskets
So first complete rebuild on a 1200 non-pv goes great. Holds six pounds of air for twelve minutes. Move on to 1200 pv. Pressure test reveals air leaking on all three powervalves.
Escaping from middle of gasket at "uppermost side" when assembled. Put one cover on a 12" disc sander and trued it up, air still leaking from cylinder side of gasket.
Do I have to take this motor apart again to true up the pv gasket surface of all three cylinders?
If I file it as is all the shavings go right down into motor.
Could try double gaskets or even buffing a "high" spot onto the cover surface to match the "low" spot on the cylinder. (Better buy some extra covers to attempt that)
I'll true up that surface before assembly next time, but any ideas on a quicker fix for this time?
