a bad oring could have been leaking air and leaning that one cylinder enough to knock. the leaner the mix the more prone to detonation it is, even if its high octane. octane is knock resistant to compression, not knock resistant to heat or a lean mixture. its a different situation. you dont run race gas any leaner than you do 87 octane, its still all gasoline and its stoicheometry is the same regardless of octane. too much air and it will burn too hot and do bad things.
