Unlike the previous ones this clutch still pulls fine, apart from the (now) very rare times where it will fade briefly.
What is happening is I get a rattling/clunking sound when the car is idleing in neutral with the clutch up. When I depress the clutch and hold it down the sound disappears. Lift the foot and the sound comes back.
I believe it is the clutch because a very knowledgable bloke who fixes them for a living suggests it is although he hasn't head it himself yet. I have also found plenty of online references to the identical issue which turn out to be the clutch. I have not seen the clutch itself so cannot comment on wear etc. It may be out of alignment but if so it hasnt been picked up before this when they were replaced.
