This is not a good sign at all. It makes we wonder how much more of the rebuild wasn't done properly. We're the counterbores cut and liners shimmed up to .014 ? Was the cylinder head replaced with an OEM brand new one? Was the head torqued down properly? Also why was the fuel pump replaced? Did it fail? If it did, were all the metal shavings flushed out of the engine ?

The cam gear spun slightly because I didn’t put lock tight on it. Didn’t think that it would matter that much. Counterbores and all that were shimmed correctly. Head torqued down according to Cummins spec. Brand new head. Fuel pump replaced because it was 840k miles old because I don’t have history on the truck. And figured it was the root cause of my 559 fuel pressure code. I did the rebuild myself so anything that’s wrong with that has no one to blame other than me. The cam gear spinning was my fault but I’m getting that fixed right now as we speak. There’s no metal in the oil anywhere other than from the break in of the engine.
