Read evidence and context
Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I would also recommend that the IMS ( Porsche calls it "Bearing base gasket") be replaced also.
Leading evidence: 'Replace also' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace also' (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.

You must replace the bearing base with the newer style.

Interesting post but....Porsche has a specific tool for replacing the RMS.

Suggestion
If it has the older style bearing base, then it should be replaced with the newer style.
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.

Found this today, don't know if it has ever been posted. There may be some dedicated gearheads who would attempt it, I'm not one of them!

The newer style RMS looks similar, but is different. Most seals have a spring on the inner area,
(where the seal would make contact with the crank).
The updated RMS has no spring. When you buy the newer RMS it has a plastic piece on the inside of it. This is there to protect it while installing it with the factory tool. After it is installed, the plastic piece is tossed in the garbage.
The newer RMS retails for $16.04.
I would also recommend that the IMS ( Porsche calls it "Bearing base gasket") be replaced also. If it has the older style bearing base, then it should be replaced with the newer style. The way you can tell, when it is removed the old style gasket is round, where as the newer style is flat.
You cannot install a new style bearing base gasket on a older style bearing base. You must replace the bearing base with the newer style. ( I believe the newer style is $40 something dollars.)
Good information woody-77, 4 sound and Tool Pants
It seems the 4th generation seal carries the 997 101 212 00 part number, and according to Uwe, of RennTech forum, the 997 engine has an extra crankshaft bearing to reduce vibration in this area. The tool also allows to push the seal in further to minimise the unsupported crankshaft length.
