Excellence say just remove the IMS outer seal!

The LN bearing has this design. The bearing has no seal on the side facing the flange so its lubricated by splash oil, so it looks like its definitely a step in the right direction. The only concern I can see is after you have gone Through the trouble of taking out the tranny,clutch and flywheel, why just remove the seal and not replace the bearing with an LN?

Well, Porsche isn't going to proclaim officially that their buyers should install the LN bearing. But I'd install the LN if I made the effort to get in there in the first place.
