Check out my thread..
my thread That clicking sound is normal. I take it the clutch disk that was used on your clutch didn't have springs in it? Neither did mine, that's where the sound is coming from. That's gear rollover. There's some play with the clutch disk and that's where the clicking is coming from. It's really nothing to worry about, that's just how that clutch will sound. Just try not to go through too many drive throughs because the clicking will just echo off the walls and it could sound like a rod knock. Only you know, it's my killer clutch letting me know it's there!
