ALL of this is unlikely. While ignored timing belts do break and cause head crashes with some reguarity, your complaint is uncommon.

Died? What happened? What sort of symptoms were you having? How many miles on the car?

If it's a burned valve, I'd also ask WHY that particular valve burned. If you can't answer that question, my own personal thought might be to consider replacing the engine with a used unit from a wreck (they're far cheaper than the Volvo factory rebuilds) because if you can't dermine why the valve burned you can't prevent it from happpening again.

There are Volvo shops listed in the center "features" pull-down menu above, some are in Pennsylvania. i have no specific experience with them.
