[QUOTE="whenfoxforks-ruled, post: 1311976, member: 73147"] Well there is 2 pistons with no signs of detonation. Pre ignition more than likely. The engine is not high compression. If you suspect detonation, stop immediately and check the plug. Detonation would burn off all them rich looking deposits. Or the service limit went over on the, piston deck for number 1, the ground strap fell off number 2, and number 3 went over and the skirt broke. [/QUOTE]
