Had the clutch changed in my C2 3 or 4 years ago, never even considered changing the IMS & the Indie that did the job never mentioned it.

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.

Porsche People,
I currently have my 996 C4S in the classifieds.
One interested gentleman is enquiring as to why a new clutch and RMS was fitted at 48K miles - four years ago now - but no ceramic upgraded IMS.
Is everyone else changing to a ceramic IMS with a new clutch - didn't get that impression from the threads on here.
Also the gentleman wants to know what IMS is in the car - assuming its original has anyone got the part number? Car is late 2002 C4S.
Don't want to give out wrong info.
Cheers B
I did clutch, flywheel and IMS bearing. There was talk of a better LN Engineering bearing than the ceramic. That would be more worthwhile. There is a risk to the engine in fitting the replacement bearing and not every garage or owner will take that risk.
Blimey some seriously 'knowledgable' punters there!
When I sold my previous pork in 2008 not a single one of them had a clue about the car (996 C4 cab tip)
Has the market changed so much?
Just tell him to get an IMS guardian, and not bother fitting a new part that's lifed and that the original is very unlikely to fail in the first place.

I think the market has changed that much yes. Same with rev ranges. 6 or 7 years ago no one really talked about them, now there's mass hysteria even if you don't need an OPC warranty.
I seen your advert OP. Lovely car. I'm hopefully in the market for a C4S next year but preferably a cab.
Question
I heard you can only change the IMS bearing easily upto a certain age of car?
Supposedly the bearing can be pulled out during a clutch change etc on an early Box/996, but on the later cars 3.6 onwards the bearing sits in a groove in the crankcases which means to remove it would involve splitting the cases.
Any truth in that? I would only buy a Box/996/7 that I could fit a new bearing to so does this discount later cars from my search?

You can replace the early upto 2006 model year 997/987 models... after this Porsche have modified the bearing to a much larger unit and this is larger in diameter than the hole in crankcase halves.

Hi Mike, excellent. Thanks for clearing that up. Definitely worth the few hundred pounds my Indy would want to do it, for peace of mind. That just leaves the scoring and D chunking to worry about after that.
This is a source reference. Confirm exact model applicability in the original material.
