New AD calls for removal of the teflon gasket at the base of the F&M adapter to be replaced with a crushed seal gasket. Also adapter must be torqued to 65 ft. lbs. every twelve hrs. I searched the FAA site fir the AD but it has not been posted yet. I followed the ad procedure and twelve hours later the top of the adapter had already began to seep oil. I am looking into going back to the original screen set up on the IO-520.
