I'm going with IMS bearing. Don't run the car. Turn it over to TDC by hand. Lock it there. Remove tranny and follow the procedure to remove the IMSB cover. That means loosening tensioners etc. I'll bet the bearing is missing the bearing cage and a side shield. I'm way less squeamish about metal in the oil than most forum members. If it is the bearing there's a good chance you caught it in time and can just slap another $10.00 fully sealed greased bearing in its place. I know heresy, but more likely than not you'll fix the problem. If you put an open bearing in, the metal debris will kill it in short order. You need a fully sealed bearing.
