If you've installed motor mount inserts like Prothane's in your civic you may have had issues with the drivers' side one that slips over the hydraulic mount.
Because of the shape of the mount it is a 2-piece insert that sandwiches the bell-top of the mount. The problem comes when forces generated at the top of the bell squish the insert apart and off the mount.
