Make sure you have correct freeplay. Chattering may be oil on the driven
disc; usually called judder. Groaning must emminate from moving parts:
operating shaft, fork, release bearing, pressure plate. (I have seen the
tapered pin wear and/or loosen, allowing the fork to turn on the shaft. )
I would (1) check the freeplay,(2) bleed the system and ensure there is no
bubbling in your bleed jar, if that's what you use. (I have sometimes had to
use a pressure system.) (3) test - Have someone release the clutch (engine
off) and watch the pushrod for movement. Put the car in gear, release the
clutch and have someone rock the car by hand. it should roll if the clutch
is disengaging.
If all that is correct, you still have the chattter and groaning, which may
entail pulling the tran for an inspection. And replacing the rear seal.
Hope this helps a bit. I'll be out of town through this Sunday. Let us know
how it goes
