I think my clutch has just started slipping. Is this a specialist job or my local mechanic?
Does it have solid or DMF and is that Likley to need changing?
How much is it going to cost?
I'm in Chesterfield so any recommendations?
Thanks

Hi,
This is the cheapest new clutch available that isn't a refurbished item.

http://www.ebay.co.uk/itm/Clutch-Kit-Porsche-996-C...

My Indy (independent Porsche specialist wink )charges £250 +vat to swap an IMS bearing which is basically remove box, clutch and flywheel, fit bearing and reassemble. So if you can get it anywhere near that that's ok. £500 all in roughly.
Obviously you do not "have" to change your bearing as that's a whole other debate. Lots of people say inspect it and if your original is ok, then leave it alone. What you should do though is flip the oil seal open if it's still there as this lets a fresh supply of oil into the bearing. That's all it needs, especially in the 3.4 as it's a stronger bearing than the 3.6 anyway.
Also you cannot get a new original bearing for the 3.4 so you'd have to look at all the other "solutions".

Also whilst in there is the RMS Rear Main oil Seal. Prone to leaking but not very expensive to renew when you're already in there. Again different opinions on whether you should swap it if it isn't leaking. Some say leave alone as they're fiddly little buggers to get to seal correctly. Personally I'd always do one as even if it's not leaking you could get it all built up and 6 months later it could start to leak. A good Indy will advise.

You should have a dual mass flywheel if your car is standard. You didn't mention mileage but either way just let your mechanic inspect it once in there. If you have no clunking when taking up drive in first and all is well and smooth in the drivetrain then you're probably fine.
Not advisable to fit a lightweight single mass flywheel to these cars as the engine internals do not like the extra vibrations caused and lets face it these engines aren't renowned for their robustness in standard trim, let alone when they've been modified.

A "normal" competent garage could do a clutch but you're in safer hands with an Indy who does them regularly and any hourly rate saving at a non specialist may be eaten up if they take longer than the specialist due to not being as familiar with it.

I can't help with recommendations for your area but someone may be along soon. Also try 911uk. Much more enthusiast based over there. P'heads is more of a willy waving forum these days than a helpful, fun forum. wink

Good luck.
