Hi there.... I have a 1992 bighorn , this morning I awoke to find that my lovely Mrs had returned from volunteer fire fighting training the previous evening and forgot to turn my truck off , it was a total mistake and she feels real bad about and I cant really say anything as I have done the same thing before (bloody turbo timers) but not for the same amount of time that she did 10 hours .
when I discovered the truck still running I took it for a run down the highway to give it a blowout , then I gave it an oil change before going to work . can anyone tell me if this prolonged idling will have damaged the engine in anyway ? cheers Scotty
