Ok, so lowered hammer spring tension didn't work.  The next common leak through this area is for the older valve seat's to crack and leak.  Remove the valve housing and then remove the valve seat, and o-ring.  The valve seat probably has a small crack somewhere around the o-ring's groove.  Until  the back of the valve seat breaks completely off, the leak can be intermittent.
