What are your thoughts on this oil migration?

And while you are at it, what size is the nut on that center bolt?

The nut, only judging from the photo (lol) appears to be about 14mm.

Not sold on a certain update bearing yet.

Actually, I am leaning towards the Pelican "replace-again-when-you-do-the-next clutch" bearing if I find a brittle seal issue...and if the seals are still intact/supple, I may just wrap it back up...or I may even go with the Nachi bearing that has a higher heat resistance in the seals. Not sure yet.

It's too bad that an oblong/oval-roller-shaped bearing is not available...it would be at home in that position and give a little bit of yield against a torsional "wobble", unlike the standard roller bearing, and be able to take more of a load unlike a standard ball bearing. Sigh.

There is another issue that is never brought up .... "German engineering" does not necessarily add credence to "German assembled"...they have cars there that were built after noon on a Friday as well. ... wasn't even assembled in Germany. It was assembled in a country that is more in-line with Russia than Germany.... alot more Fridays in Finland if you catch my drift.

Reason I asked about the center bolt nut was it look large in your photo, and I was concerned it was a 22MM.

Roller bearings are available, but have no installed base and have not shown engine builders of note any advantage over hybrid (read ceramic) ball bearings. If you really want to do this right, put in an IMS Solution; oil fed and no moving parts, the only known permanent retrofit.

According to my Carfax, and a quick call to the dealer, it was found that the IMS seal had been replaced at less than 5K miles.
