I have a pm6 that sounds like its leaking down the barrel. I took the frame off and the leak seems to be coming from the back part of the solenoid where the black and red wires plug into the noid. All the bolt orings look great but I replaced the three big ones that go on the outside of the can anyway which didnt fix anything. The funny grid shaped oring that seals the solenoid seems to have one tiny spot in it where it is raised up and not flat. Could this be it? even though its is on the opposite side from where the leak is? Thoughts and comments are appreciated. Thanks!
