bearing failures are hard to indemnify by oil analysis, cuz if its ok i wont show and evidence but ones it touches the crankshaft true the oil film it will start and go bad in very short time (less then a oil change period) , my personal experience based on s52 and 4.8is, and f10 m5 engine just listen to it carefully in a closed room like a garage, every 1000-2000 miles.
