There is no OEM IMS bearing available from Porsche. What the dealership quoted you was probably a flange reseal, which consists of replacing the seal on the IMS flange - that's why the job looked so cheap. That's it.

There is no part number associated with anything IMS related other than a complete IMS assembly (complete shaft, 3rd revision) OR the flange, seal, and nut. Bearing and bearing support (stud) don't have part numbers, as they were never intended to be replaced.

Can someone educate me on what the roll of the intermediate shaft is or point me to a good link to how the engine is designed.

There is also a very good series of articles on it in Excellence Magazine, I think June, July & August of 2010.

After reading the pelican article all it seems one needs to do is check the oil pan during each oil change. If you see metal get the car checked out.

Once it gets to that point I think you are toast....or at least the motor needs to be torn down in addition to an IMS replacement. Metal floating around in the motor = not good.

Well the car is in the shop, got my fingers crossed that the retrofit goes well. :dance:
