That's the number #3 cylinder, which I figured was toast since we had no change in idle when we removed that spark plug wire on the road. I thought it was cracked, but it looks like I melted my first piston. Not entirely sure why it melted, all the others pistons look fine, the looks good, and so do all four plugs (well #3 is oily). I did notice that I have some exposed wiring on the #1 fuel injector plug, I think I might buy some injector plugs and rebuild that harness.
