What dampener? And where is this part/device located?
I'm confused over your description of the problem. You can't push the clutch pedal in, but the clutch is disengaged? Did you mean you can't disengage the clutch? Or, did I miss something entirely?the clutch pedal goes stiff, can't push it in and the clutch is disengaged(
do I need a special adapter to remove it like the beamer crowd?Yes if you give it three clutch presses rapidly the CDV delays each release until you overtravel the clutch itself (or bottom out slave cylinder) so it goes solid and then you get to wait four or five seconds after you release the clutch before you get any drive. The CDV was added to allow you to dump he clutch with the launch control. When I drive my car very hard on hills roads the changes are close enough together that the release is a lottery to see when you can gas it up and often you get bad $$ smells from the clutch.
