I don't think its a wear item at 48k miles. My supercharger puts extra strain on it, and the older model yea E85 M's have an oil filter housing that is poorly designed. One of the bolts from the hydraulic tensioner screws into a "floating" mounting point. A replacement filter housing I got has that part fully welded.
