Need help to identify this isx...

[jared1751]

I appreciate the info. When an engine is "reconditioned " from Cummins is that a complete rebuild? or a fix only what is broke or out of spec? Is it possible this is a million mile plus block? At 370k on the engine now I will address the fuel pump And whatever else I find as I research this motor. I appreciate all the help and all the knowledge on this site. Thanks
