Aside from the "10k 996" threads banging around (of which I take a great interest!), this is a slightly more technical question...

re: the advert above... aside from looking like a tidy car at a very tidy price, it mentions a new clutch. My question would be, what possible damage could the previous clutch have done to other mechanics of the car i.e is this worth a look or would a damaged clutch have done harm to other parts of the car?

Cheers.

It doesn't say the clutch was damaged. A clutch is a service item - you fit it and as it does its job it starts to wear out, just like brake pads. I'd check for an invoice as to who did the job and whether they changed the RMS and IMS seals whilst they were in there, but if they didn't and there's no leaks then it's no big deal.

With respect though, it appears your mechanical knowledge is somewhat limited so I'd urge you not to commit to buying any 911 without a pre-purchase inspection by someone that knows them well. smile

lol my knowledge is a little better than I let on, I just read back what I wrote and it is atrocious :-)

ps I will be getting an inspection on any 911 I view. I am not suggesting I am buying the above car, my budget extends more towards 15k, but I wanted to see if there were any known issued with clutches going and any damage they could do a la IMS / RMS etc that are "porsche specific"

None that I know of, although the clutch fork may need checking, same for the dual mass flywheel.

It depends upon why the clutch was replaced. If it was just worn out then the odds are there is no collateral damage to anything else. I assume though that the tech who did the clutch job inspected/checked all the rest of the hardware and replaced anything that needed it, including the flywheel and either found the FW servicable or if not replaced the flywheel. A bad clutch, a slipping clutch, can 'take out' a flywheel. And FW's can expire (the dual mass feature breaks) on their own.

Now if the clutch was replaced because the previous owner liked to drop the clutch and do smoky burnouts to impress the ladies...Then even if all the normal wear/tear items of a clutch were replaced even if the flywheel was found to be just fine, the rest of the car (mainly the transmissions/diff and axle shafts/bearings) have suffered some from the treatment that led up to the clutch needing replacing. The engine might be a bit ragged too...

Thus it would be very nice if you could get your hands on a copy of the clutch job paperwork and read what (if anything) the tech wrote down about the reason the car was brought in the symptoms the owner reported, and what he found during his diagnosis/repair.

Sincerely,

Rockster.

That's great thanks for the advice, I may contact the seller as that motor appeals to me.

Just having my clutch replaced as I type - the wearing on the clutch had in turn worn out part of the slave cylinder. I had it replaced for £90 although it wasn't *strictly* necessary, it just would not have felt nice to drive afterwards.

So if the clutch isn't smooth, might be something to consider, previous owner may have opted to save the cash.
