<VV> clutch or throwout bearing shaft noise??

[Markpowhatan at aol.com]

For the third time this year I had to go into the differential and the last  
time showed a oil leak onto my clutch so I decided to put in a Clark machined  
throwout bearing shaft with two oil seals....  now my clutch sounds just  
like a zipper when depressing the pedal.  I first suspected the cable was  
dragging on something.  Removing the tunnel cover proved it wasn't but the  noise is 
in the bell housing.  The Clark "snout" has fine machining grooves  in it I 
noticed,and I wonder if they are causing the noise when the throwout  bearing 
slides over them.  Has anyone else ever experienced this after  using a 
machines throwout bearing shaft?
