Disappointed in Cummins Engine

Shane Perch is correct. Now they got sleeves for Cummins and Cat engines that did not originally come with sleeves. So that is no problem. All these engines though with a little luck will easily last half a million miles with no problem, but the breaking down can happen to any engine. I worked with locomotive engines which are big diesels and they would break down when you least expected them just like the little diesels on coaches. The important thing is that you hope they break when you have warranty or else it is expensive.
