And the IMS bearing does not tear up the engine case, it is totally inside the IMS shaft.

Well my engine sounded like a running washing machine full of rocks with no water in it when it was shut down. It was rebuilt and the damaged parts that had to be replaced were a timing chain paddle, the actual IMS, the oil pump and a few bent valves. I suppose it was caught at the exact right time, there wasn't a lot of metal in the engine. The lifters and oil cooler were replaced too, to be certain there were no stray metal bits to wreck the rebuilt engine.
