Gun Leak

[gkap27]

I just opened up my gun completely to fix a cocking problem with the bolt, but now when I attatch the air source, all the air just goes straight out of my gun, like out of everywhere: the barrel, the hose area, the screws, everywhere! It also made an obnoxiously lous noise to put in the air. I believe I did something wrong when rebuilding the gun, either with putting the Valve in wrong, or it may have a leak. I remembered to put the big hole facing towards the barrel of the gun for the valve. If anybody knows something that I did wrong, could u plz say something, or If I may just have a leak through it, or through anything else. Plz Help!

cock the marker before you aired it up?

Could be the cup seal as well.

Gkap27 is my neighbor and I have been working with him to try and fix the gun. So, according to this thread, it is recommended that we oil up the o-rings and replace the cup seal. If there is any other recommendation as to what we can do please say so. Thanks to those of you who posted here.
