Only 35, 000 miles, have driven manuals for 30 years. Car just started wine noise when clutch is depressed - loudest in first gear, cannot hear wine going through gears except a less audible wine from 1st to 2nd. Occasionally I hear a low wine if idling. I am leaving in neutral at lights, ect. Clutch performs functions and shifts with no problems. Bearing, Slave, etc, ? Any advice? Car drives fine otherwise.
