My X-Valve has recently developed a leak down the barrel. It stops when I hold the trigger in so I already know that it's in the power tube. I have tried oil to see if that helps. It did, but briefly. I have tried using smaller carriers (1.5, 1, .5, 0) using the same o-ring but to no avail. I have read all of the stickies regarding leaking down the barrel and am still unable to get the leak to stop.
I have also tried different springs out of desperation.

Is there something I'm missing or should I name my mag "Linda" because it's possessed??

Help me Obi Wan Kenobi. You're my only hope.

do you have shims in there, take them out. try it without and changing the carriers again.

[THE Biscuit]

tried with and with out shims

What's your tank pressure? Have you used an alternate air source?

[THE Biscuit]

Tank pressures are all over 3k

[Tempted (Banned)]

I certainly hope not. I was asking about output pressure.

[THE Biscuit]

ah! It just started leaking last time I played with it midway through the day. output on the tanks I have used are ~850.

OK well a couple of things. That power tube space can be finicky. Using a new oring and starting from the smallest carrier, go UP carrier sizes. Ive come across a few that needed larger carriers. It doesnt happen often, but it does.

Also, check the reg pin orings. Make sure they are good and that there is no crap on or around the reg pin. There is a slight chance the dump chamber is over presurizing. Most likely, I doubt it, but check it.

I also recently developed leaks down the barrel in two of my mags in the same weekend. The level ten was tuned to perfection and have been running leak free for at least a year. Turns out the power tube oring in the carrier was goin bad. Very minor leak, came and went. Correct spacer, shims, input pressure, all that good stuff. Bad oring.

I completely forgot about this thread. It was the red o-ring.
