lol donated or Detonated? i guess detonating could be the same as donating, except the only donating you do with a detonated piston is to the trash bin.
what did you do to "Detonate" the piston? especially the 3.9L, that motor was built by the hands of god, right next to the LS1 assembly line, across from the forged 4.6L termie plant and around the corner from the 4g63 factory.
im just giving you shit. are you modded at all? i think you might want to diagnose why youre getting detonation/knock before firing it up again.
