*** The biggest difference between Cummins and any other mfg is that Cummins publishes all the information you'll need to work on and maintain that engine without incurring fees to access that info. As Rawze said, if your just gonna pay dealers and shops to do all your work then it really doesn't matter which engine you choose.

As for thee 2010 and newer ISX fuel pumps, just spend a few hundred $ every 350,000-400,000 miles to replace the components in the pump head and you will be fine. Other than that do an EGR tuneup every 150,000 miles and stay on top of the other scheduled maintenance provided by Cummins and you will be fine.

And stay away from 3rd party/aftermarket engine components, programming and other gimmicks. The ISX will perform exceptionally well without anyone messing around with it.

Thank you JimT you have been the only one to try and answer the wuestion and give good adviceunlike other ppl that think wer here to be talked down too I just want too know what engine should I go with I am use to pre emissions engines and just want the most reliable engine not the most powerful and yes I do maintains my engines better then anyone should I change everything usually with in 15,000miles but still just scared of the Cummins which I have always loved Bc of the stories I have heard but thanks again for actually helping not talking $$$$ and not helping at all
