Is there such a thing as a cheap Porsche?

I began changing my oil for the first time today. Drained the oil and dropped the sump. See the attached pictures of debris I found in the sump. Most of it is plastic but there were 2 metal pieces large enough to pic out. They appear to be part of a bearing, about 4.8 mm long, ferrous.

I did a quick check of the filter and didn't seem anything obvious in it. I will tear it apart tomorrow and do a better check. The oil was pretty dark, supposedly it had been in the car for 2 years.

Is there anything in the engine besides the IMS bearing that would shed pieces like this?

Thanks
