273 spark plug mishap

Yes that is the car. It died in Susanville California at a stop light, so we drove down with a trailer and rescued the kid and car...

Pishta, After seeing it in person, a wash and wax wouldn't have done anything for it and as far as the plugs, judging with a flashlight, the threads have dissolved from the combustion, so a thread chaser would not make it right. They didn't use just one or two in the oil burning cylinders, they used a complete set of plugs..
