Bryan serviced my phoenix in 2014 after I fiddled with it, so I've been carefule to keep my fingers off except for cleaning(on this reg anyway). It has developed a squeal/ honk wile under water if I take a quick breath. In a similar thread, SDAquamaster suggested lubing the balance chamber orings. Looking at my log book, it has been close to 180 dives since the service. Didn't realize it had been that long ago. If I try a little lube, is it recommended to replace the hp seat to avoid double grooves? And how often is it recommended to grease if it is? Or should I just stop breathing hard just to see if "yep, it still does it".
