Spark plug melted badly!

Is this Swifty's old car? That cylinder might have been running really lean with the fuel pressure/fuel supply problem we were having and/or the problem got even worse.

The melted plug and hole in a piston is pre-ignition though. Pre-ignition destroys a motor extremely fast, it can do that to a piston in a couple seconds.

Yes this is swiftys old car. Yeah i dont know the alternator completely went out on my way home from your shop so I put a new one in it Friday afternoon. I probably put on.. 100-200 easy miles on It after the alternator keeping an eye on The voltage gauge on the turbo timer and never noticed any voltage drop. Then I was moving it from my work cruising along fine then wham it ran like crap for a couple seconds then died
