I did a rather long roadtrip this summer, so I wonder if I just really coaxed this goo out of the motor by running it on a 9 hour drive one way. Car has 83,000 km; a little over 50,000 miles.
Udo had the IMSB changed last May, and this is the 2nd oil change since then. Indie dropped sump plate and cleaned it out at the time, so what you see is post-IMS swap material.
The LN magnetic drain plug had the slightest black film on it each time. Can't say if the previous filter had metallic debris at all.
What you see is fairly representative of what I found in my oil filter while doing the pre-hibernation oil change today, roughly 30 flakes this size.
Nearly all ferrous, no big chunks, just minute flakes.
Should I be concerned with engine health here, or just monitor?
