Well boys, I dropped the deto piston with half con rod off at a local race engine builder and he is of the opinion that it " hydrauliced". Again this is just an opinion. So for the sake of chits and giggles, I am going to remove the case tonite and make a little gopro vid so that the images are more clear and we can get a real good look at the damage. He showed me some deto pistons and they look nothing like mine, but that doesnt mean it didnt deto. The hydraulic would explain why there were no symptoms of deto, no codes, no knock sensor and the fact that it suddenly happened without warning. I dont know why it would hydraulic but he has seen it before on his own 04 rev turbo.
Anyway, I off to make a vid. Will post shortly.
Oh yeah, wont be getting the octane checked in my drum....anyone want to guess how much that test cost.......
Dr. Evil voice.....One million dollars....lol
Does that mean you were burning antifreeze in his opinion to hydrolock? I have seen a piston left running on a antifreeze leak, it had traits of deto but the whole exhaust side of the piston was radiused off...down to the ring grooves.
