I'm having some intermittent clutch issues that I think are related, but I don't have a good sense of what's going on. My mechanic wants to drop the engine to inspect the pressure plate, but I'd like to have a bit more idea of what's happening before I spring for that. The clutch is a LWF/RS clutch that was replaced 2 years ago and has about 12K miles on it. It was replaced after I started having significant issue with judder/shaking/shuddering on engagement. At the same time the pedal box was rebuilt and the slave cylinder replaced.

After the work, the clutch was great for a while. More recently, it shakes/shudders on engagement intermittently, and the clutch pedal stiffness varies between easy(ish) and smooth, to very stiff. When it's stiff, I can hear something squeaking from under the car when I push the clutch in, but when it's smooth, the noise seems to go away.

Any ideas?

Thanks!

 

For the record, there is no need to "drop the engine" on a 993 to service the clutch, flywheel or transmission. There is a significant number of hours billed to do this and it involves breaking lots of connections on a 20+-year-old car that should not be messed with unless absolutly needed. My experience is that I was once quoted and billed the hours for "dropping" the engine and when I visited the shop I observed it was not done. If the job was quoted this way go to someone else as competency + honesty are requirements, your mechanics suggestion falls short in one of these two aspects.

It sou​​​nds like the clutch spline shaft is dry, causing erratic engagement and clutch pedal feel...

 

Another possibility is the Clutch Fork Shaft I have seen a couple of these seized solid but both were 964's https://www.design911.co.uk/fu/prod4...3---996---997/
