for an engine to run away it basicly has to have fuel from an outside sorce. no way its gonna happen from an ipr valve.
also before we say who is responable for damages. look at the paper work you signed when you droped it off.
what other work has been done to the truck in say the last 90 days before this happened.
things that I have seen cause this is a failed turbo charger oil seal, a torn injector o-ring, thoses are the first to that come to mind anyway.

I am in Pesacola Florida.
No work has been done to the turbo charger. I do know that oil from the turbo can cause a run away. I have had injectors replaced several times by the Dealership in Utah.
If there was a bad o-ring on one injector, would that be able to creat a run away. That would be just one cylinder. I could see if all were bad, but how does one or even two cylinders getting fuel cause a run away?
Thank you.

npccpartsman this is Dan. I was responding to cheezits comments. About the work that had been done on truck.
If there was a bad oring in the injector this would have manifested itself ealier. The reason I took it to the dealership was what I thought was lack of fuel. Am I correct.

lack of fuel is not as bad as to much fuel on a diesel. to much will melt a diesel down very fast.
to awnser what happens with a cut o-ring... the fuel will that passes the cut oring winds up in the engine oil, the oil level will then rise and overfill the crankcase that at somepoint give the engine a fuel sorce other then threw the injectors. My personal experance is some were around 30-35qts of deluted oil can do it.

My opinion is that the tech that told you that is probably inexperienced. There would be a good chance that something catastrophic may have happened and if the tech was hooked up, he was watching the IPR trying to compensate, making him think it was the IPR that ultimately caused it. And NO, the IPR alone won't cause a runaway. I could believe injectors coming apart, flooding the crankcase with fuel, the crankshaft splashing in the overfull oil, kicking up oil into the crankcase ventilation, then into the intake.

The owner of the last dealership I worked at told me about the 3 c,s. I don't know exactly what they are now But the first is care, cause, something. basicly saying when you hand over the keys and sign the R.O. the dealership is responsible for yuor vehile period. We had a kid crash one on a road test and it was on our insurance. That is in PA it may be differant there.
