Metal in the filter means metal circulating through the entire oiling system. No way around it to fix it correctly. Pull it out, tear it down and clean out all the passages and galleys. If it ran OK then pistons could be reusable. All bearings should be replaced and you REALLY need to find the cause of the problem. Bearings don't shed material for no reason. Do it right or you'll be asking the same questions again soon.
