mellonman Posted December 7, 2011 Share Posted December 7, 2011 im going out on a limb here i would not have a clue about what would make that noise but,physics could come into play as the noise could be air trying to travel through a weak bov diaphragm/valve just a guess dont know what the bov components are Link to comment Share on other sites More sharing options...
