The IMS retrofit is designed to be a precautionary step (as in before the bearing starts to go), not a reactive one. If there is already metal, and in particularly ferrous grit, you would be advised to stop there until you know why, and repair that before doing a retrofit.
The cheapest IMS retrofit (done by a shop) is nearly half the cost of a replacement engine, if you guess wrong, you end up spending more than you needed to in the first place, and ending up nowhere.
