Please help identify foreign debris in engine oilpump(low pressure pump)

My friend asked me to look at his 2006 F450 (6.0 diesel) Engine wouldn't start. No oil pressure on oil pressure gauge. No oil getting to oil filter. No oil getting to relief valve on pump. I removed the oil pump and found some foreign material(looks like pieces of a bearing). The engine oil pump was messed up as I expected. The question is.... Can anyone tell me where this came from? I am pretty sure a bearing came apart somewhere. Pictures are attached

needle bearings from a failed roller lifter. The roller wears a flat spot and all of the needles fall into the oil pan

That is good news. I can probably get by with removing and cleaning the oil pan, installing new oil pump/timing cover, and replacing bad lifters. HOPEFULLY the filter caught everything that made it through the oil pump before it pooped out.

I wouldn't be so quick to slam it back together, if the roller is spitting needles, then it is most likely dragging on the camshaft lobe.

I would remove ALL lifters, then stick a borescope into the holes of the bad lifters to inspect the lobes. If the lobes are chewed up, then those filings had to go somewhere too.

Better safe than sorry.

You need to pull the oil cooler also. Inspect under the oil cooler for metal. I no metal your injectors and high pressure should be ok. Disassemble the oil cooler and you will find the front oil/inlet of the oil cooler will be full of metal. Inspect your camshaft, when lifters fail like that cam lobes are usually eating up. I done about 5 of these with just replacing camshaft, lifters, oil cooler, complete front cover kit and clean out oil pickup passages. If metal made it to the injection system proably looking at a complete engine.

Yes I had one that was so bad metal made it into the injectors. It would start and run (with a little help) but only fired on 4 cylinders. Also the offending lifter was mushroomed so bad it couldn't be removed from the top of the bore.

Do the heads need to be removed to remove the lifters? I just got the valve covers off, and it looks like the heads need to come off. the service manual I have is not very helpful. It is 4 inches thick and doesn't really tell you which page to turn to find the section you need.

As long as the lifter end didn't mushroom they can be fished out of the head. If one doesn't come out the head has to be removed and the lifter driven out thru the back/underside of the head.

Maybe I have a different year than dannyboy950? The hole in the head is way smaller than the lifter. There is also a plastic tray on top of the lifters. There is no way to get them out without removing the head. I definitely have a mushroomed lifter(wont come out). What is the trick to getting that out? Cylinder 5 intake lifter failed. Cylinder 5 intake rocker arm fell off, and cylinder 5 exhaust rocker arm is bent and cracked.
