After I got over the shock of the metal in the filter I made a plan:
1) drop the pan and check it
2) Operation Metamucil: do a couple of quick (5 minutes;around the block) oil changes to flush the garbage out as much as possible
3) Put in Joe Gibbs 10w40
4) Put in an oil pressure sensor and gauge
5) watch the oil pressure gauge for signs of the apocalypse.
Step 1 complete. Pictures attached. Good news: very little in the way of debris. A piece of the snap ring from the original IMS bearing removal. Looks like it didn't make it through the screen on the oil intake. Indeed, looks like it may have just dropped into the pan. The big chunk is a piece of silicone/gasket. Some fine ferrous material piled up by the corner of the plastic slosh-gaurd. All in all not the yard-sale I had feared. BTW, got the filter out that I saved from the IMS bearing change. Those gold flecks were ferrous and not gold after the oil came off. As mentioned before the old IMS bearing was in one piece when removed and didn't show any signs of having lost material.
Thanks for the advice and ideas. I'll update this again after the oil pressure sensor/gauge are in.
