Maybe you guys will have a better idea on how to fix this than I do. I decided to clean and change all of the orings on my 08 SLG after letting a buddies kid borrow it for a few months. He is young and I didn't explain how to maintain the marker properly to him when he borrowed it since it is my loaner gun.
I got the gun back and it was caked with paint and mud, inside and out. So I figured it was a good time to replace all of the major orings and just give it a good cleaning.
After replacing all of the major orings on the bolt and back cap, as well as in reg reg, I aired it up and it began to leak from the port on the front with the set screw plug in it. See pic below.
I have never had a gun leak from this type of set screw plug / port before. I decided to investigate, so I removed the set screw and found that there was quite a bit of paint in the threads and that some of the threads looked worn out. Very odd considering that it was not leaking when I gave it to him and I KNOW that he did not wrench on it. I went ahead and replaced the screw with a new one and aired it back up again, this time it leaked even worse.
I have quite a few of these 10-32 set screws around, so I grabbed another new one, put some blue loctite on it and put it back in, letting it sit for a few hours before airing it up again. This time the leak "almost" stopped but I can still hear it if I put my ear to where the set screw is.
Am I missing something obvious here? It does not seem like this is an area where an oring would go for a seal. If the screw cannot seal this port I guess this means the threads are bad and the body is shot? If a decent amount of blue loctite cannot seal such a leak, I would not imagine teflon tape would do any better (but maybe I am wrong)?
Has anyone else had such a leak crop up on their SLG?
