I have a 1994 Plus 8 with 26K mileage. An annoying intermittent squeak (more noticeable when idling) has developed which disappears when I just gently touch the clutch pedal. I have well lubricated the pedal shaft but this squeak still persists. The clutch otherwise is working fine as with the rest of the car. A new cluch cylinder was fitted by the previous owner about 12 months ago. Possibly the clutch bearing? Any suggestions other than ear plugs?
