There is a slight shhhhh noise coming when clutch pedal is "not pressed", as soon as clutch pedal is pressed the noise goes away. And when AC is switched on, this noise increases a lot and sounds more like taktaktaktak As if some loose metal parts are hitting each other. As soon as clutch pedal is pressed, the noise goes away.
What could it be? input shaft bearing? throw out bearing? pilot bearing? Mechanic said its the bearing making sound and when AC load is put on, the sound increases. But which bearing is it?
