Hi Guys / girls. I have a little problem when I depress the clutch on my van. When about half way down its makes whirring noise until you get to the floor then it stops. Does the same when releasing but stops when foot fully off. Had a old mechanic ( retired ) have a look & he said these were prone to being faulty and said it would need a new fly wheel, clutch kit & slave cylinder. the clutch does not slip at the mo but was told its only a matter of time. Any thoughts anyone ?
