Well iv had a slight whining noise for a while now which i couldnt locate, not wheel bearings etc etc

well finally today it got a whole heap louder, very suddenly.

and it is there only on the over run in 1st gear, wether the clutch is pressed or not, doesnt do it under acceleration in 1st or at all in any other gears or neutral

is my box donald ducked?

Its a classic UK 2000 by then way.
