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(
Reading between the lines, it sounds like you may have a clutch with the friction surface coming loose. You didn't mention the clutch slipping unless the whoosh noise is it.
