Here's what I see. Potassium and sodium spike.
Look for coolant leak. Is it using coolant ? Aluminum could be bearings but I doubt it because it's still a pretty low ppm bUT if coolant were going in the oil than it would wash the bearings and cylinders.
When my oil cooler failed at 660,000 miles, I had a spike in potassium and sodium and iron as well.
Iron is a bit high but nowhere near danger levels. I like to see it at 4 or less with mandate removed but I've seen it at over 200 + on a stock truck.
Not trying to scare you but I had copper and aluminum spike just befor my cam bushings let go. That turned into a inframe at 960,000 miles. Good luck friend.
