Correct.
Furthermore, the seal is not damaged by detonation per se. Rather, the detonation leads to severe local overheating. The excess heat then MELTS the seals. Then, with the lower seals no longer in place, combustion pressure, heat, etc. damages the upper seals on the injectors and popping sounds can be heard.
My thought is that the occasional detonation is not a problem. There is sufficient time between detonation "episodes" to permit things to cool, so no damage is done.
Track-type driving gets things heated with no chance to cool down ... and the trouble starts.
Again, the seals are not being "blown off" via uncontrolled explosions; the seals are being "melted off" via uncontrolled heat build up.
We need better control of the detonation, probably via a revised ECU tune.
Please correct me if my current understanding is incorrect.
