I know four guys whose Cummins diesels burned up owning to injector problems.
Two were under 250K, two were newer than that.
You probably know more than I but I wouldn’t touch ‘em at present.
I always liked them because when they were running well, you could not find anything better.
But that was in the early 80s...
And yes,,,,injectors could be a problem with any diesel, but I never saw one burn up...saw them wear out..saw cooling system failures..and overheating..
I’d say about 85% of issues with diesels are fuel related..
If you run one...you have to be a babysitter with your fuel. and filters.. if you do, they pay you back.
I also have a few acquaintances who run the Dodge’s...but before I make a decision, I will do the research.. I am not a Ford fan...just one of those things..
