This has probably been explained to death already, but I'm not the fartest smeller on the block. I called my cummins dealer and inquired about a small job that I wondered could be covered under warranty. He explained to me that Dodge buys our engines without warranty. Cummins will not do warranty work on them, you must go to DC for any engine work unless you want to pay out of your own pocket. I thought we had a basic warranty covering things like engine internals (pistons,rods,crank,bearings etc. ). I hate to drive by the DC dealership much less have to go to them for engine rebuilding>
