Could be a lengthy process, but you may have to just change 1 and repeat the de-gas process.

You can always use the soapy water method to locate your leak.

Could it be an outer can oring?

[MachineGunCrew]

hard to say since you can't hear it. you can pop your frame off and gas it up and check your manifold orings.

also, did you try a different reg and gauge setup?

[paintballhead5]

I have 2 cp regs and they both do the same thing. I only have one gauge though. I will replace all of the outer orings on the engine and see if that helps. If not I will pop off the frame and check the manifold orings.

[paintballhead5]

I replaced every oring in the engine. Then i check the manifold orings. Upon listening closley to the feedneck/front of the gun i can hear a very faint leak. As i move the bot around i can hear a shift in the air flow. Which orings would cause this?

[MachineGunCrew]

Internal orings. Bolt guide/outer bolt/inner can.

[bnkr king]

Inner can is usually the culprit, the one that makes the seal when you push the 2 pieces of the HE can together.

[Japy]

Probably the inner can. Those are usually the last ones I touch.

[Shooter28]

If it's leaking down the breach, it can only be 3 orings. Outer front can, inner front can, bolt guide tip. If you can seal your finger on the face of the bolt and feel pressure building, it's the guide.

If you leave it gassed up between games then you would just loose air. If you turn the gas off then with that leak you will obviously have a drop in pressure before your next game when you gas it back up. If it dropped 20 psi in Less than a minute than you should be able to hear it pretty well. Check it with the grip frame off and check the back of the gun as well, where air would vent from the gun after each shot.

[samuelkeesee12]

If it is leaking down the barrel it could be any of those 3 o-rings but they probably wouldn't cause the fsdo. That could be the sail o-ring.

[paintballhead5]

Which oring is the sail oring?

[Tumnisio]

I would also try a different reg and see if that helps. I bought a CP and had similar issues, turns out the regs can come in two different pressure configurations, depending on the piston. No one really seems to know about this for some reason

That might not be the issue if you have one of the newer regs, and with the pressure drop you are describing, but could very well be a factor.

If it turns out that's the case, ANS is the only place I've found the replacement pistons http://www.ansgear.com/Paintball_Reg...arts_s/316.htm

I have a bob long 360 ill try off of my vice. Now which oring is the sail oring?

[brrain]

The one with the most diameter It's three Orings back from the face of the bolt on the outside on my stock he bolt I'm looking at ATM I'm unsure if the lurker bolt is different but it's the outside one with the most diameter

[gutgut2hi68]

the sail is the rear most o-ring on the bolt. If you look at your eigen, its the only o-ring on the bolt.

[paintballhead5]

So i changed the sail oring, bolt guide tip oring, both can orings, and the inner can oring up front where the can snaps together. The leak cannot be heard anymore but the gun still loses 20 psi in 3 mins. I cant tell if its coming out the face of the bolt or out of the can. I tried a hyper 2 i had the same results, so thye hpr is not the issue. I also tried my bl 360 but when i unscrew the asa it purges the whole gun with that reg on.

[Gisgo09]

^That's normal. That reg uses a poppet and once you relieve the pressure on the high pressure side of the poppet, the forces holding the poppet closed are gone, so it opens up and dumps the air in the reg and the gun out the asa.

[samuelkeesee12]

Could be pneumatic lock out. Check it out on zdspb.com

[gutgut2hi68]

His FSDO problem is very strange though. Just about everything we recommended hasn't fixed the issue. He said he gets FSDO with 3 different bolts, and all the fixes he's attempted haven't solved the problem.
