Hi guys: Wondering if you can tell what bearing this is from the size of nut?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Are you referring to the nut showing at the IMS flange? And the bearing behind that? IIRC there are two styles of flanges: a shallow one and a deep(er) one. However, I seem to recall that even with this difference one can't alway be sure the same bearing style willl be used. I think you just have to remove the old bearing and then with it out know which size/style (single row vs. dual row). Looks like the RMS is leaking but not very bad. SOP is to replace the RMS and the IMS flange and bolts in case the leak is coming from the IMS flange seal or the bolts. The new improved IMS flange has a 3-ribbed seal (vs the old one's single o-ring) and micro-encapsulated bolts to prevent oil from seeping through the bolt threads and out around the bolt head.

Thanks, I was told that this engine has the "upgraded" bearing from late 2005, because of the larger shaft and larger nut. Just wanted to confirm that if anyone knew that. I don't want to mess with it if it is since I wouldn't be able to get the bearing out anyway.

Looks like so to me and you are wise not messing with it.

That looks like a 997 big bearing IMS. Nice to have, as seem to be very reliable.
