The cooling jets have metal tubes where the oil sprays the Pistons, but the body is molded polycarbonate (plastic).
I here ya on the self repairs. I would think as a shop owner I would be very uncomfortable standing behind my work if I didn't remove a broken piece of metal from the pan.

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.

Mr Hagg, if you replaced a component, i.e. a broken cam gear, would it not be as part of the repair procedure to remove the oil pan to retrieve the broken piece? As this situation shows, it would remove the mystery of future repairs now possibly chasing "ghosts".
I realize there is more than just the metal pieces, it is more of a generalization.
Yes you should and if there is a lot of metal in the oil pan Id remove the oil pump if you see signs of metal going through it then replace the oil cooler for sure...

I saw Mr Hagg use an electric oil pump on a shop cart to pump clean oil thru the engine when a 2250 customer had fuel pump ceramic plungers breaking apart. Good way to flush debris down to the pan.

I pulled the valve cover and one of the clips that covers the spade connector on the jake solenoid is missing so I'm about positive that's what it was.
