If you lose a jet you will lose the piston in short order. The metal almost looks like a gear tooth. Hard to tell. Almost looks like a piece of the rings also.

Where on the cooling nozzle does the plastic come from? As far as I can see they are a bent metal tube that are connected to the oil passages on the block with a banjo bolt. CM871

The cooling nozzles are made of a brown plastic roughly the same color as the debris you have in the pan. The connectors on the engine brake harness also have this brown plastic too, so you should consider both as culprits. As others have said, if it is in fact a cooling jet, that is a serious issue that can cause engine failure. Nothing to play with. Inspect them thoroughly and ensure it is not one of them. http://www.benya.com.tw/proimages/pb/CMC27BK-POJ0.jpg

I kinda agree with hammerhead. Any serious work where something has come apart, the pan should have been taken off and cleaned out, but is not something every mechanic would think of. Only problem is that debris can get into passages and not drop all the way to the pan for a month. A good measure for sure, but you may still end up with a piece of leftovers in the bottom of the pan the next time it is apart.

I did look at each nozzle from underneath with a bright flashlight and they all appeared identical and did not appear to be cracked or broken in any way. I would lean more toward the engine brake harness, as I had the cam replaced last year and 3 injectors this year. Do the connectors attach to the harness with big zip ties? That would explain the pieces of that too.
