Seems to me that you are describing exactly what happened to this engine. Note the piston damage at 12 and 1 o'clock of the piston. ( Yes that is the rings you are looking at ). It can effect 1 cylinder and not all 8.

This damage on this one was purely detonation damage. It can be caused by Timing, too low an octane fuel, wrong spark plug temperature range. A vacume advance not operating correctly can do this also.Last edited by Weasel Diesel; 04-20-2010 at 06:56 AM.
