Valve seat falling out @81800miles?
I have a 2003 chevy 3500 2wd duramax. injectors replaced @ 41000miles and @ 81700 miles noticed more smoking at idle. Went to the dealer and was told the injectors needed replacing again. I said I was going on a 3000 mile trip and would it be OK? Was told that it would be OK just the fuel economy would go down. 115 miles into the trip the engine lost all the coolant quickly. What had happened was a valve seat had fallen out on #8 cylinder and caused alot of internal damage. A replacement engine required. My question is "can a bad injector cause the valve seat to fall out burn a "V" in the valve and torch the head? Or is it just my bad luck.Anyone with simular experences?

ouch, took a chunk out of the valve
a quick google search indicates that there may have been an issue with some of the earlier models loosing valve seats as GM did some revisions to correct this in the newer ones.
