Coudl well of done a piston too mate, I done a plug in my xe nova, it still ran ok with a new set so I left it, when I took the head off there was one lo comp piston

Amazing how well it still went and i still ran a 13.05 1/4 with it like it

There has gott be a problem somewhere for it to melt a plug, faulty injector maybe?

Sounds like you have got detonation issues mate.

Det explosion is massive, no plug or piston in the world will stand up to heavy detonation.

You may well get away with just new plugs, but get it looked at before you drive it/hard again.

May I suggest the fuel pump wiring?

Those plugs do melt, but fueling is usually slightly lean (or det is present)


your need to do a leak down tst and comp test to check for damage.
