Went to change my oil today, and after I poured out the oil, I came across these small specks. They look like specks of metal but they break apart using my fingers so I’m not sure if it’s part of the rod bearings or crank. Also theyre not magnetic. I changed the oil back in September and saw the same thing but decided to drive it a bit and see if the engine blew up. It never did, but I’m still seeing these weird chunks of what appears to be rocks. Car is a 93 945t
