That would be sufficient to do damage - the fact that it went noticably flat shows that the fuel mixture went massively lean, which could easily have nipped the rings up

On mine, I had been cruising at a steady speed for several hours and gave it a quick blat to overtake a car and the FPR blew off (I didn't notice) and then I was "encouraged" by the Scots to drive a bit quick, so several high speed blats saw it melt
