I have had magnetic drain plug last 3 changes. I have always seen a thin film of black slug, no specs as OP's show
I tried to see if anything from the plug would stick to a magnet but that doesn't work.
What I did find by accident the last time was I rubbed the film off on to tissue paper and when I put a magnet to the film stain, it was attracted to the magnet. I think there was a tread about this before but I could find it with search.
I haven't cut open my filter yet as Expansion tank replace took priority
I hope you find your sump clean. I have done that a couple times and that does give me some piece of mind to find it and the filter debris free

Ok, so I finally pulled the oil sump and it looks really good! Just a couple bits of chain ramp material.
However, when I wiped up some of the oil from inside the sump plate, i noticed a few metallic looking specs which turned out to be magnetic...
And I also noticed that there are cracks inside the sump plate, has anyone else ever seen this? and can I still reuse this cover? No leaks before removal...
So, where do I go from here? Is this amount of metal normal? Should I just put this all back together and check again in a few hundred miles?
