I doubt if its close enough to you, but I would recommend www.rpmporsche.com (in Cheddington, a half hour from J20 of the M25). I've been using them for a few months now and am very impressed. They provide excellent service at a very reasonable price. What's more Ollie who runs the business owns a 944T and he's very familiar with working on 944's.
Best regards,
Peter.

Its possible from your description that the clutch fork fingers are cracking or bending.
The other option is that it could be a faulty release bearing, they can wear so much that they are not tight enough to pull the clutch pressure plate fingers back enough to release the clutch.
The other option, it could be the hydraulics, the only way to tell is to examine them. It may be worth changing the fluid, if it comes out black, its often a sign the seals in the master or slave have disintergrated.
One last option, which does happen, is that it could be the spiggot bearing has rusted/seized.. this means whatever happens with the clutch, the torque tube keeps spinning relative to the crank/flywheel... thinking about it, if your car has been stood up a while, this could well be an option.
You can take the engine out to change the clutch, but unless your planning an engine swap ;o) its easier to take out the gearbox and pull back the torque tube.

thanks Jon, It does come and go, with the engine off pumping the pedal it did sometimes go stiff and not all the way to floor then would clonk (from inside the bellhousing) and release. Am I likely to cause it any damage driving it? Not worried about bits that may already be failling but dont want to damage other bits.

Hmm... sounds like the fork or release bearing then.
If you drive it, the worst that would happen is that the fork which may have a crack will finally break... Additional damage would be possibly the slave cylinder over extending and the seals going west. But thats about all that could happen. If there is something wrong with the clutch, the only additional damage would be to whatever is already faulty.
If you said it was slipping, then I would probably say do not drive it, as flywheels are getting harder to find used, a new one is expensive and a slipping clutch can knacker the flywheel.

Exeter OPC had 2 new flywheels in stock when I bought mine - and they only wanted 55 notes for them as well. Probably the other one is long gone now, but you never know.
Also the flywheel is about the only bit of my engine below the head gasket that didn't have a hole in it so if anyone gets desperate I might have a spare in Devon as I think I got one on the race engine as well.

Sounds like a good idea although to do more than two cars in a weekend you would need a fair amount of space.
I did mine in the spring and I would factor a day per car with two people working assuming you have every part including flywheel bolts, rear main seal, spigot bearing, exhaust hardware, gaskets and misc spare nuts/bolts.
A good selection of tools go without saying
A Transmission jack would be handy or possibly hire a workshop?
I'm happy to help with a car but my back is screwed so unless its on a ramp not much help at all.

Too late.
We are doing Tony's tomorrow (and maybe Sunday if we are S.L.O.W [8|]) and will do mine later in the year.
John it's good to hear that your Spec clutch has worn in now [], I tried it once when you'd only done a few thosuand miles and it was pretty much off/on and nothing in between []

Would hope to be able to return the favour of all the help I have recieved so far, and I am a lot more knowledgeable now, Clutch is out and centre was knackered all of the smaller centre springs had escaped and bits were loose - many had been for quite a while I think - its rattled for as long as I can remember. Just reassembly to go then

Paul,
I think the torque is just getting beyond what your clutch can take.
When we decided to put the current clutch in there there wasnt much else worth using unless you wanted to build up massive leg muscles or put up with a juddering clutch. Since then there has been some developments for something much more suitable without the clutch being super heavy or juddering.
If your interested, I can tell you what to buy and where from, and we will fit it for free!! With a promise that you can drop your car down one weekend and collect the following weekend garaunteed! Or if you want to stay in a B&B overnight, we would also be happy to do it over 2 days.
We will also contribute towards the cost of the clutch for you It was always going to be a bit of development.
