Actually, IMS failures remain "the silent death" right up to the moment that the engine jumps time and pistons start hitting valves. We have seen an absolute ton of metal in the oil of cars that were in for regular oil change service and still running just fine. When you pull the sump cover, there is metal everywhere, so the engine is done at that point, and then I usually had to make a difficult phone call to the owner, who was totally unsuspecting.
And the IMS bearing does not tear up the engine case, it is totally inside the IMS shaft.
