A wide variety of problems can set off the Guardian, just about anything that generates ferrous debris in the oil. If the IMS bearing starts to fail and triggers the Guardian, the engine will have to come apart as it is most likely now full of abrasive debris, but at least it could be saved before total IMS failure reduced it to a boat anchor.
