Has Porsche ever come out and defined this service interval, or do they just let owners discover it on their own? I don't use the dealership for more than parts -- has anyone ever had a dealer recommend an IMS replacement proactively?

The reason or that is that according to Porsche, you cannot change the IMS without taking the engine apart on any M96 or M97 engine, and as they do not let their techs take engines apart, you simply are billed for a factory replacement engine. Solves their problem, and yours, well, sort of anyway...........
