Use a few feet of small tubing as a stethoscope, stick one end in your ear and move the other end around where you think the leak is. When you're directly over the leak it will be very loud through the tube. Be prepared to pull the barrel out when the leak starts so you can put the tube near the transfer port in the rear block. If it comes from the transfer port it can only be leaking around the valve seat, valve rod delrin seal or the second o-ring from the rear on the valve housing.

I know you could just listen at the barrel end but that's not safe.
