Yeah, agree with the others. Hope you tell him to be sure and get the
right plugs to go back in. It look to me like it is totally melted,
possibly wrong heat range. A friend put the wrong plugs in his Hyundai
Tiburon (sp? ) and melted holes in two pistons.
I would think if that were the case they all would have got trashed. But
then, it could be a "This 'ill work" plug.
I've seen them take stuff apart. Nuts, bolts, clips just get put anywhere
and I mean anywhere. Would not surprise me if it were a result of parts
or like a socket left in the cylinder when a head was put on.
One thing for damn sure. The plug contacted the top of the piston. I don't
think it was a tool left in there, as it would just sieze because there
isn't enough room in there for a socket or much any tool. It looks like it
ran a few rpms to get that chewed, although it could have done it in a few.
I'd be surprised if the car runs decently at all, even if he gets this
straightened out. Looks like a long thread plug, the wrong one for that
car. The right one could not be inserted far enough to contact piston head.
