Finn,
Quite obviously you haven't been following the thread, Ed has exhausted most possible problems.
Not to my satisfaction, he hasn't.
It's either a foreign object or some other factor yet to be identified in this thread.

I'm no reotary expert (see! I can't even spell it!) but I have seen some pretty bizarre damage on piston engines caused by detonation/preingnition. Like piston rings broken and I can easily equate this to an apex seal. I haven't seen this discussed much on this thread, there might be no "witness marks" left behind. One clue might be plug color. It could be something like an intake leak, mixture problem, incorrect heat range plug, timing issue, even a long gone piece of hot carbon.
FWIW, Tim Andres
