Newbe here and potential first time buyer of a Porsche. The one I' m interested in is a 1999 3.4 carrera with 113000'on the clock According to the docs there's no evidence of clutch replacement RMS or IMSB. The former is a deal breaker but in every other respect the car is of real interest.
Wth a partX it's easily affordable. My quandery is should I go ahead and buy and put it into an Indie for a precautionary IMS upgrade and clutch? This work may already be done but no receipts. Advice please, thanks

'99 car is dual row IMS and not a concern? (do your own homework, don't rely on me)Wth a partX it's easily affordable. My quandery is should I go ahead and buy and put it into an Indie for a precautionary IMS upgrade and clutch? This work may already be done but no receipts. Advice please, thanks
Thanks. I checked Revolutions website and according to the USA class action there was/ is a 1 % failure rate with MY 1998 to 1999, dual row. I guess on that basis it's a fairly safe bet that the IMSB's are pretty solid in the 911's for those years. Do you have any more comments that might be heful in reaching a decision YES/NO to purchase? Cheers

In summary, if it’s lasted this long, unless you’re very unlucky, it’ll be fine. By replacing the bearing in situ you’re inviting more problems.
There’s much more than the IMSB to worry about on a 996. Suspension, radiators, hard brake pipes...

For the clutch then treat it like any other car, drive it and see if you think it needs changed. If you think it does then do the RMS at the same time.
On the IMS bearing it's one of the strongest they used, I personally wouldn't bother. If the failure numbers revolution are quoting are correct then another way of looking at it is would you spend £1,000-£1,200 on insuring yourself against a 1% risk probability, when the impact would be a 10-12k rebuild? I wouldn't, I don't think the numbers add up, but only you can decide if they're ok.
As other posters have noted these are old cars so what has been replaced, parts and labour are not cheap.

The IMSB has done 113,000mls yet you think it needs changing immediately?
Most bearings changed by paranoid owners turn out to be in great condition - leave it well alone & focus on other areas as mentioned above.

Well guys today I took the plunge and bought the Porsche (after another test drive). I'll get a fresh MOT and 6 months warranty. Late August it will go to an indi for a post purchase check and 2 yr service, so fingers crossed etc. I do have a 2K fighting fund but I hope it won'be needed. The warranty does give me some comfort. Thanks for your responses, I'll keep you posted

Yes the oil leak was picked up at the PDI and and MOT and sorted’. The mechanic
To whom I spoke reckons there are no major issues as far as he can see.
However I will be having the car fully checked at a Porsche Indie in the next month or so and will ask for a fresh oil change with the filter split for debris. Hoping there won’t be any surprises but I do have a fund backed up by warranty. Collecting tomorrow. Thanks for your help.

if you check the mot histroy, there is an ongoing oil leak. It might be light (RMS) or it might be serious. in any case, you do not want a flat 6 engine to leak oil. Be careful and good luck!
Meh it's not an issue for them to 'sweat' a bit, active dripping is another matter. It's not worth pulling the gearbox to replace the RMS, better to wait until it needs a new clutch and keep an eye on the oil level.Eddh Thanks for your input. The RMS was done about 8 years ago and another seal was done just last week bell housing I think. Anyway I''ve had a couple of longish drives since delivery and no leaks detected. Health check by Porsche indie soon. In the meantime I guess nothing to worry about short term
