So I decided to take my enmey apart to get an idea for how to do so, and to clean some paint spatter from a shot I took while playing.
Once I had re-assembled the gun I re-connected my air tank and noticed a small hissing that sounded like it was coming from the ENV123 Barb Tower area, I then took it back apart, inspected the o-ring OB7033 and the barb tower to find no damage.
I put a little DOW-33 in there to try to create a seal, which when aired up and dry fired twice, seemed to diminish the hissing, but it was still quiet, sounded almost like it was squeaking and still somewhat noticeable. The o-ring kit that came with the gun had no replacements for these o-rings. Any recommendations on what to try from here?
