That's why the new LN Engineering bearing has an open seal on the rear of the bearing....because it allows engine oil present between the bearing and the flange to lubricate the ceramic ball bearings.
Leading evidence: 'Replace flange the seal was' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Lubricate ceramic ball bearings' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I replaced the IMS flange with the LN Engineering flange, (just in case).

and the part shown is an O'ring so My guess is the new housing used an oring and the old one used a gasket

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Since the biggest expense is the time/labor to gain access to the rear of the engine where the RMS/IMS reside one is really only out a few extra dollars in parts cost to replace both items and the bolts, just to be sure.
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.

My car previous owner, sent me by mail some extra maintenance paperwork he had stored.
While I was looking at the RMS seal update, I saw a line that could be the IMS front seal upgrade but with the Porsche dealer gibberish, I can't be sure.
So I assume it mean bearing cover front intermediary shaft removed and reinstalled .. but who am I to know
Anybody got the front seal replaced if you can confirm that would be great
That would also mean the dealer if not that bad after all. For info the caris a 2003 911 C2, and this repair was done in 2007 as the car had only 15k miles on it !

bearing COVER FOR intermed. shaft removed and reinstalled with a new housing and seals - the housing is the original number and the inner o ring too... cant find that outer oring so it could be a new part (after PET) shows on RT as a $7 part with NO SS numbers
99610511201 is a gasket? and the part shown is an O'ring so My guess is the new housing used an oring and the old one used a gasket
hope that helps
The part number 996.105.024.06 is a new IMS flange so it would appear that they did replace. Ironically on an 03 you should have already had the newer version of the flange.
When I was working on my 00 I did the flange "upgrade" with a kit number 993.105.017.02 which included the flange, bolts for the flange and three new bolts for the case.
However, mine is the dual row bearing with the shallow flange. With an 03 you have the single row bearing with the deeper flange so that is the part number they listed on the invoice.
Since the RMS and IMS are so close together if there's a leak in that area no one can say for sure which item is the source of the leak.
Both are suspect and both are generally replaced. That is when replacing the RMS to also replace the IMS end cap with a new one with an updated 3-ribbed seal (vs. the old style with a single o-ring) and 3 new micro-encapsulated bolts.
The bolts are important cause the holes they thread into go into the crankcase and ol from the crankcase can make its way past the threads and seep out and from under the bolt heads and make a leak.
Since the biggest expense is the time/labor to gain access to the rear of the engine where the RMS/IMS reside one is really only out a few extra dollars in parts cost to replace both items and the bolts, just to be sure.
Sincerely,
Macster.
yeah they only replaced the seal Ya know so the burnt dirty oil has no where to go other than work thay bearing down to failure. They didnt do anything other than pull the flange and replace the flange seal... And it was leaking... So the bearing seal is also shot.. But they didnt replace that one
Sorry but no. The seal they didnt replace and cant replace with out replacing the bearing in the bearing seal, It is part of the bearing. And porsche says it cant be done with out pulling the engine and cracking the case. (but it can be done) So Im sorry but no, it wasnt done.
Here's a photo of what they probably found.....
The upper shaft is the RMS (where all the good oily juice is coming from)
The lower circular flange is the IMS.
The second photo is the IMS flange cleaned up.
I replaced the IMS flange with the LN Engineering flange, (just in case).
The seal is attached to the flange. When they replaced the flange the seal was replaced. The bearing is not "shot" because the flange is leaking. The only way to know if the bearing is shot is by pulling the bearing and having a rush of oil come from the IMS (since it's hollow). Or by seeing that the IMS bolt is loose or can move outside the parameters of where it should move. Oil is present between the IMS bearing and the flange. That's why the new LN Engineering bearing has an open seal on the rear of the bearing....because it allows engine oil present between the bearing and the flange to lubricate the ceramic ball bearings.
Sorry, Kyle, I'm calling you out on that...
