1G Metal in Oil Pan (pics attached). Looking for feedback

[Jdm07j]

1990 talon 50k ish original miles. Bone stock. I personally only drove it for maybe 50 miles. In the process of doing some much-needed maintenance as I just purchased the vehicle not that long ago. Car ran in open loop when purchased. Traced some very major boost leaks, including the intake manifold gasket. Was able to get it in closed loop after replacing the gasket, injectors, spark plugs, wires, dsm link, coil pack and removing emissions/replacing all boost lines. I Never ran over stock boost but I did find evidence of a past boost gauge. But when I say the car was bone stock when I bought it, I mean it. Emissions and all, nothing missing and completely factory. Just the boost gauge tap. At the very least I’d assume a boost controller was added at one point but can’t prove it.

Nonetheless, I had the car running very smoothly compared to when I got it and idled like it was supposed to and in closed loop. Fuel trims spot on. I didn’t have any weird sounds or any knocking. Next stop was a turbo replacement (was leaking oil) and timing belt, water pump, oil pan (because of dent and leaking), etc. I did suspect a possible issue with the turbo bearing prior to pulling it. Dropped the leaking/dented oil pan for replacement and found a bit of metal. Not a crazy amount but enough for concern.

Wanted some feedback from some with experience. Is this bearing material? Some of the pieces are darker and one almost looks threaded on the backside. Only one of the pieces actually sticks to a magnet. Oil pan is still off, I stopped there. Just looking for opinions before moving forward. Thank you

Cut the oil filter open and see if there's anything on the filter media.

Could it maybe be left over cast material? Some of it is magnetic.

Hard to see the pic. Could it be composite hg material?

Follow the line of oil pump sprocket into the block and see if you can get a visual on the bearings where the rear balance shaft rides. Make sure nothing is out of place there. Lots of stories of that balance shaft spinning bearings, myself included.

Update: Checked the filter today and it was clear of any metallic debris as far as I could tell. The darker/black pieces in the pictures do appear to be hardened rubber or gasket material. It initially appeared to be metallic due to it being semi reflective and hard but when I squeezed it again today, it had some squish to it and broke apart. It didn’t seem that way in the beginning but that means that the actual metal I found is down to about 4 tiny pieces. I looked up along the balance shaft bearing area as mentioned and can’t really see anything that looks out of the ordinary. All the oil squirter‘s are intact and look fine as well. The two cylinder walls that are visible appear to be clean and smooth as well.

Aren't they piece of turbo's journal bearing or/and thrust collar/bearing? Maybe the previous owner blew a turbo before you bought the car.
If so, sometimes this happens, some piece of turbo internal parts that remain in drain tube or oil pan suddenly come out when you change the oil in the future, if the previous owner didn't clean well (especially inside drain tube)

Rubbery pieces of debris? Probably gasket material from something or chunks of sealant squeeze-out. If your filter is clean, oil pressure was "normal/nominal," and the car was running before, I would personally reassemble, double-check everything per the manual, and enjoy the car.
