I have a 97 ex that makes a noise that sounds like a bad throw out bearing. Only makes the noise when the clutch is engaged. When you depress the clutch pedal it stops. Strange thing is I just put a new throw out bearing in and it didn't stop. Wondering if the pilot bushing could be the culprit? Also sounds bad when I get the rpms up and let off the throttle and let it wind down, then its really loud. Any help would be much apriciated.
