The metalic flakes....check your rockers and pushrod ends and valve tips. If you had too little oil up top on that valve, you may have wear in those items.
If you can clean and replace this stuff, you might get a few more miles out of it.
You can get small ceramic magnets at Radio Shack. Put a few in the cylinder heads in the path of the oil, but not blocking the returns. Make sure you don't create an oil drainback problem, but just have the magnet close to the oil flow and away from anything moving. 2 to 4 per side will catch a lot of metal if it's there.
