Sounds like its a problem with the clutch on the way out, I asked "Doctor Dave" the Classic Cars magazine technical guru:-

The main extra wear it causes is to the clutch system and pedal assembly...and of course, the longevity of your left knee!
all best

Thanks very much for this, I suspected as much to be honest, I think I will put up with it till the clutch gets worse, it seems ok at the moment
The Clutch is £800+ to change (including a new RMS seal) so I will live with it for a bit! (unless you think it could damage the engine?)
Kind Regards
Edward

The usual cause for clutch pedals to go squeaky is the clutch nearing the end of its useful life. As the pressure plate wears, the cover plate 'fingers' adopt a position further out as the springs continue to create a clamping load to prevent the pressure plate slipping.
I'd reckon that fitting a new clutch kit would:
a) make the clutch a lot lighter
b) remove the squeaking from the pedal
as just oiling it will only be treating the symptom, not the cause!

Dear Dave,
The clutch pedal on my 1998 porsche 911 Carrera 2 (996) gives off quite a loud squeak when pressed and depressed, most annoying as the rest of the car is very sound and solid!
The pedals hinge from the roof of the foot well, making oiling hard, any ideas how to solve this most annoying problem!?
Kind regards
Edward
