Metal chunks on drain plug magnet. ID them?
What is this material from do you think? One little chunk came out on the drain plug magnet and I spent 30 minutes fishing the rest out with a magnet. This engine has 300k on it and is still running great with no noises. Found this on a random oil change. This engine had a severe turbo failure in 2010 before I got it. Think it took 9 years to come out?

Maybe part of the turbo bearing?
I lost a vacuum pump bearing and it came out the drain years later.
What is the size compared to?
Size of a quarter?

Yup, I would say turbo debris too. I just fixed an '86 MB 300 SDL that had 2 turbos go and that debris looks very familiar...Mark

Thnaks everyone. Its about the size of a silver dollar, a tad smaller. Magnetic. Looks like part of a failed casting. Was skeptical they would linger in the crankcase after 9 years and 7 oil changes but can't think of anything else in engine that would look like this. I checked turbo thats on it now and its mint- smooth as butter. Have run 3 oil analysis over the years on this engine and other than the first one when I got it, they checked out well. Not so much after the turbo failure. I'll see if I can find it and post it.
