I surmised that the combination of the "V" slot which lost its ability to support the side of the seal and the softer Hurley seals lead to one fracturing and that piece taking out the following seal.   So I now know that the wear specification for that apex seal slot is something to pay attention to.

I went to new rotors and now use Tracy Crooks apex seals (much, much stronger than stock or Hurley).

Ed, I was thinking yesterday that if someone (Tracy) produces seals that are slightly wider than stock, old rotors can be cut wider and given new lease on life?
I know there is 3mm seals, but not everybody likes to use them. I do.
Joe, I'm glad you are OK. You can fix the engine in no time. Happy Holidays to all.
