Pressure Plate rattle......

If you have anywhere from 1/4-3/4 of a inch of play,depending on the way you like your pedal would be normal.Now does the noise go and come if you press the pedal all the way to the floor?Does it appear only on light pressure?Does the noise get more noticable with RPM or just at idle.Does it happen in gear or in neutral? Is the linkage really loose and every thing in line properly,mrmopartech
