Sounds like throwout bearing is noisy. it could be anything in the throwout bearing system. A week or bad clutch slave cylinder would not hold the correct pressure on our of the bearing when in use. Also when you buy clutch kit it seems to be the bearing is the cheapest part they puttin em sometimes. But the whining in the noise only from the inside I would say is definitely the throwout bearing. Only my opinion but I would investigate. Good luck Napa Dan.
