The rattling noise can be 3 things:
If the clutch was operating normally it would be the TOB going bad or the input being so bad the input shaft is walking.
Diaphragm going out and binding up.
Spring popping out and wedging between the diaphragm and clutch.

I think it's one of the later cause the clutch is not disengaging. Going to have to replace the clutch and the diaphragm.



When inspecting the MC/SC, Did you have someone pump the clutch pedal while you watched the SC operation?
