Is it ok to leave our engines running at idle for hours at a time?

I used to be a meter reader for DTE. My jeep would run for 4-8 hours 6 days a week. A few months in I shattered the #6 piston on my 4.0. I did a full rebuild. I bought a stroker kit and did some work to the head and block. I continued meter reading for about a year driving the jeep everyday. Then I got a new job. Anyway long story short the motor broke the cam earlier this month, the shop claims lack of oil.

I wouldnt do that at all, what I would do is go get a optima battery, and go to somewhere like walmart and get one of those fan/heater combo for your cig lighter and use that and the optima battery shouldnt go dead plus it will save you gas and life of your truck. just my two cents...

no engine does well with extended idle, even the diesels. on the diesels most guys that do idle for extended periods will idle up and or idle against a load i.e. exhaust brake, trans, something.
gas engines are the same, you need to either high idle circa 1000 rpm, and you should load the engine up somehow. loading against the trans will be hard on the trans so thats a bad idea.
i never do extended idles without a way of loading or maintaining high idle. when in a situation such as yours, i either crack the windows or have good blankets depending on the situation, then before shutting down i run the hvac at either extreme of the temp untill the cab is at or near that temp, then shut down and sleep or do whatever. typically the cab will stay comfortable for several hours, at which time i will repeat the process if needed

I Like Tires
I let my company f150s do it all the time. Leave the AC running in the hot summer when I'm out on projects. Haven't ever had any negative affects from it, but that certainly doesn't mean it's okay for them.

I forgot to mention that when I let my f350 idle, it was a high idle. Have a toggle switch under the dash to make it idle around 1000 rpm, because the other poster is right. Long idles are bad for every engine, not just gasoline engines.
