As these cars are now more than a decade old, does the ims bearing failure rate increase with age? (seems probable) even on the later 997.1 larger version? earlier ones seem like they most will likely get replaced or have been replaced. Or of course they have cratered already.
Perhaps another novice question - is there an access point or could you drill a hole through case flange to run a borescope to identify size of ims nut 13 or 22mm? is this worthwhile?

The DOF type oil feed is both problematic as well as unnecessary;' just remove the seal.
There is no realistic way to borescope the IMS center bolt, take it apart.
