Rebuilding properly would cost more than used.

The metal in your oil is either a symptom or one heck of an odd thing. What is the oil pressure when the car is up to temp. It'* low right?

If it'* at 40 the bearings should be good. Another indication of a chipped piston.

Replacing pistons in our motors is tough. They are very finicky about wanting to be align bored and checked by a machine shop and having the bearings resized etc or they usually last about 200 miles after you spend all the time and effort doing just a piston or just a bearing. It really sucks because it'* such a durable motor in every other way.

Pistons don't knock, bearings knock. You have two issues.. probably related. You probably pushed too hard and had a ton of detonation, that led to a bearing also taking a hit.. which led to the bearing going bad. That would explain your beaten plug and the bad bearing.
