X valve leaks

[11 Bravo]

I have an Xmag that really is not broken in yet. xvalve of course. The other day it began to leak from the vent on the side of the valve. I replaced the internal o ring and it worked fine for about 2,000 shots. Now its doing it again. When I had it apart it seemed to be well greased, but since I didnt have the correct grease I didnt add any. Again the grease seemed to be adequite. Also I regularly add oil.
Any ideas as to what the problem could be? Also what grease does it require?

X valve
Velocity 280 fps

Check your input pressure. 650 to 700 is good. over 800 it will leak. this is the relief hole for the reg.
Turn down the marker velocity.
Do you get any shots with it leaking?
Does it stop leaking between shots?

Last chrono was at 276,276, 280.
It still shoots, but during the shot you can hear the leak reduce (less pressure).
I use this bottle on three other X valves and dont have this problem.

If it is leaking out of the little hole on the side of the reg body, that would be the high pressure bleed off. Check/clean/lube the reg pin orings.

In the valve or on the bottle?

In the valve.
