The Cummins 5.9 is not as easy of a rebuild as the big Cummins. It does not have the cylinder sleeves for rebuilding like the big diesels do. A big diesel with sleeves can be rebuild may times, while the little 5.9 has to be bored every rebuild, and that weakens it and shortens its life. Because of that, many call the little Cummins 5.9 a throw away diesel. I would expect to get 500,000 to 1,000,000 miles on that little "throw away" diesel. But one that has not had proper maintenance is anyones guess!!!
