Piston #7
I'm a victim too now. But I brought it on myself. 5 passes all hotlaps 18:1 afr 12.5 1/4 full weight / heavy stereo. Drove it 2 hours home afterwards and for another 6 months. Thats how you do a top ring BTW.
Since I got a bite, not really, just showing how far you can go (stupidly). That was the only piston affected and it took a few runs to get it that bad. I actually expected worse. The cylinder wall was not messed up by it and the car has 130k on it. I have all the new rings and a new piston, but I found a problem with the cam and i'll be ordering a new one (the exaust lobe on #2 looks like it got hit by the roller, pitting on the tip and a scratch before it, lifter appeared to jump over something and crash down.)
