Has anyone experienced the tightening ring on the secondary filter housing working itself lose after 2 or 3 hours of running time? After the first episode(which was after a filter change and bleeding) and getting back to the dock a qualified mechanic checked and reinstalled the filter, etc again. Seemed good, but 3 running hours later its worked itself loose again, more diesel in the bilge.. Threads look good (ie: don't appear stripped), Yanmar authentic filter element carefully centred and ring threaded fully up and hand tight, etc. 

Any suggestions?
