sorry and thanks!!
Busted damper springs cause the clutch plate to make a 'crack' noise when you're engaging the clutch - also makes a crack if you stand on the gas when you've been in overrun mode.

'Catastrophic' hmm, that would be when one of your damper springs jumps ship and straight between the clutch disk and flywheel plate - or your release bearing disintegrates and does something similar. Release bearing is usully the less gentlemanly of the failures as they have a nasty habit of ripping off the clutch plate fingers. All usually resulting in a rather uncivilised loud bang. (Your bank cards will make a suicide bid at this point in time usually.)

Signs that your release bearing is on the way out are usually rumbling, grinding noises as you put your foot on the clutch pedal - that or it squeals like a stuck pig.
