Runaways are not good for any length of time, The pistons need to be inspected for valve contact, the bearings need to be inspected for damage. You can check the pistons by removing the injectors and using a borescope. And you could use Cummins Insite to Isolate the cylinder with a cut out test if needed. It would be a good Idea to tow the truck to a Cummins shop for a complete assessment. Please dont forget to rate my service. Thank you for allowing Just answer to assist.
