The noise went away, tightening the clutch cable screws helped which is against logic.Unless that sound came from upper end of fork hammering sides where it sticks into engine compartment since dust boot is kinda torn. Clips and bigger spring are replaced. Are those clips likely to fail?

Tightening the cable pulls the release bearing towards the pressure plate. This would make the noise go away by putting the release bearing in constant contact with the pressure plate. This is bad because it means the release bearing will spin ALL the time, and will wear out prematurely.

 

The clips are not likely to fail if they're new, unless they were installed incorrectly or the release lever was moved around too much prior to the engine and trans being bolted back together.

 

Probably was the whole bearing and lever assembly rattling around because the clutch and hill holder cables are not adjusted properly or the release lever return spring is missing or not installed correctly.

 

Loosen the clutch cable so there is about 1/4" of play at the top of the release lever, then adjust your hill holder cable until the cable just starts to pull the lever on the hill holder mechanism. The slight tension on the hill holder cable pulls the release lever forward and keeps the release bearing out of contact with the pressure plate.

If you do not have the hill holder, there should be a spring on the release lever to pull the lever forward. If the return spring is missing the same thing happens. The release bearing will just touch the pressure plate, and will bounce around and rattle as the engine spins.
