Add in the shock/pressure wave from knock / lspi on top of high cylinder pressures... I don't know a ton about diesels but afaik this isn't an issue with them while it is for a gas DIT motor.

Also, consider a highly stressed DIT whose ECU has adapted to it's environment, then put in a bad tank of gas... the ECU will compensate but not perfectly...
