100% of the 6.0's have some problem sometime.
100% of the Duramax engine will have some problem sometime.
100% of the Cummins engine will have a problem sometime.
100% of every engine created will have a problem. No such thing as a vehicle that does not have problems.
Education/maintenance are the KEYS to longevity and trouble free miles with any engine. Especially the 6.0
I look at my truck much like a relationship with a female.
When she has a problem, she will drop subtle hints. So will the 6.0.
When you ignore those subtle hints, she gets a little louder. So will the 6.0
Continue to ignore her and the hints are no longer subtle. Same as with the 6.0
If your still ignoring the signs at this point, your in for a world of hurt. She has been screaming at you, you ignored her, and now its all over. Same with the 6.0
Get educated by reading the 6.0 forum. You will quickly learn the shortcomings of the engine, how to tell when it is happening, what to do when it happens and how to prevent it from happening again for a long time.
Since your interested in this breed of female, you need a good set of ears to pick up those subtle hints, gauges.
Oil temp, coolant temp are the two most important gauge you can own in one of these trucks. Monitor those like you should, and your female will never have to scream at you. You will pick up the issue at the whisper stage. She will be happy for that, and so will you -- your wallet -- and the female you married (if applicable).
Most of the problems with the 6.0 are coolant based issues. Thats right, coolant. More specific is the lack of maintenance of the coolant/cooling system will lead to the famous head gasket popping. Mechanically, these engines are a beast. There really aren't that many "common failures" beyond the oil cooler/Egr cooler failures that wreak havoc when ignored. (when ignored, this is what pops those head gaskets)
The appearance of the interior and exterior of a vehicle is not a good indication of what happens under the hood. I worked with a guy that was absolutely ANAL about how his car looked, ask him when he changed his oil last and he would give you a blank stare. He didn't even know where to put the oil into it.
