OK well i hear a leak coming from my feed neck I think

..I have a tech t bolt engine.I put in the stock bolt and hear the leak as well.the leak sound like its sizzle a little bit but can clearly hear it if you put your ear to the neck. All O ring are new and only have a case through them. After i hear the leak i replaced the O ring right behind the feed neck and still leaking..

I put my finger in the bolt and no pressure builds up and i can clearly hear it still.
I am shooting consistant 289 290 292 288 290
my dwell was on 12 and i dropped it to 9.
abs dwell is stock on 4

any help would be greatly appreciated...
thanks

if you shoot let's say a pod or so, does it go away?

it could be a lubing problem. mine does that on air up, i shoot it 5 times and it's gone.
try relubing the bolt. don't drop your dwell, put it back to stock.

[mikeygrubtail]

well i am using the tech t gunsav Can i be putting to much..I mean i dont know i thought i didnt put alot on just a light lube i didnt glob it on.As far as the dwell it leaks on stock 12 and 9 so i dont think that would matter

yea i tried shooting a bunch of times still the same..kinda annoying me

he did.

can't you read?

[phant0m0]

yeah, check all those damn o-rings.

[marcusgar21]

there are 2 o-rings behind the feedneck in the marker. make sure you get the one that is right behind it. not the farther back one but the middle of the 3 in the breech...

[mikeygrubtail]

Yea i did change the O ring rite behind the neck,Could the leak be else where and i hear it in the neck? I dont hear it anywhere else on the gun

[mikeygrubtail]

ok did the Noid again...Still there re lubed check o rings replace O rings on the outside of the noid Still there..

lets say i am mistaken and when i stick my finger in the bolt and it coming from the bolt what O ring should i replace? where can i find it? i mean i changed most of them and it still there maybe i made a mistake and its coming from the bolt.cant hurt to replace that one too.

Give this video a look see (1:40 or so). He mentions that if you have the bolt stop installed wrong, it will leak.

Also, relating this to the BL Marq's, i would assume that you want to avoid getting lube on the surface of the bolt stop.


Regarding the stock engine, I had a leak heard in the feedneck, and I found that it was the smaller o-ring on the back cap (the on that slides into the bolt).


Good Luck.

What kind of lube are you using? I've cured faint bolt leaks by switching hater sauce for plain ol' dow33.

[MConstantine]

I have the same issue, I lubed it and checked the O-rings. I hear a very very slight leak, like a popping or sizzle leak like the thread starter mentioned but very very light. I can't stress enough how light this leak is, but the leak is there.

I switched to the stock bolt and there is no leak, it's quiet in there. I only hear it from the TechT bolt.

I was thinking of putting a little thicker lube on it. I currently have Baby Oil lubed up on the gun and the gun shoots perfect, it's just that slight leak that bothers me. Maybe I should use a thicker lube on the O-ring where the bolt and the stopper meets?

My theory is that the Baby Oil or thin lubes are too thin and can't hold the pressure enough and run a little when aired up so a little thicker lube might solve the issue of this popping leak.

Let me know what you guys think.

Thank You

You are going to get "use a DOW 33 or 55". Try one of those. Baby oil is not gonna work properly. I would go with the DOW 33 but it's preference from what I've seen.


Not sure if serious....Baby Oil?

[i8somepie]

Please do not keep using baby oil on your marker

Use a Dow33 based lube, or another good grease like Lurker Lube, Monkey Poo, TechT GunSav, or Slick Honey/Slickoleum. On top of that, refrain from using any oil on the bolt of your G4. You can thin out a grease a little with oil, but don't use only oil on the bolt. It'll blow off quickly and you'll see increased wear of your orings. Oil does not seal as well so you will see leaks develop over time.

Baby oil is in no way meant to be used in any pneumatic application. After using baby oil, I would replace all of the orings within the marker. You don't see companies like PE, Bob Long, Alien, MacDev, and so on providing or remotely suggesting using baby oil on their markers, AND it will void your warranty with every single one of those companies.

[8765]

Baby oil is mineral oil, however baby oil has added fragrances, which might not be good for the orings. The main reason not to use oils is they get shot out rather quick, leaving the orings dry. I've seen people use oils, but they're replacing orings fairly often. It should be okay to mix grease and oil as lube. If using grease doesn't help, you may have to change an oring or two.

[MConstantine]

I ordered Dye Stick Lube which I believe is Dow 33, I'll clean out the baby oil and try using that. I also used baby oil on my reg.

Mike from ****** suggested baby oil and apparently his G4 works flawlessly, he was using stock bolt though and I have a TechT bolt. I also don't experience the popping leak with the stock bolt as I've mentioned before.

I haven't played with it since I started using Baby Oil, I just switched recently. I also didn't check for that popping leak until recently so I don't know when it started. My O-Rings should be fine since I didn't play with it since apply Baby Oil.

I'll update on whether the popping / sizzling leak goes away after switching to Dye Stick Lube.

[MConstantine]

I honestly don't care what the feud is about nor will I take sides, I'm here for info and suggestions not about a feud.

I don't care about the infractions, they can ban me if they want. I won't waste my time with it. It's petty.

I find both sites helpful in their own way , not the best way to promote Paintball by bringing petty feuds like that to the table when all we want is information and expansion of paintball. Everyone will have different opinions. It's childish.

Anyway, I'll update you guys on if it goes away with the Dye Stick Lube like I said earlier, I have a feeling it will work.

On to the real discussion instead of entertaining idiotic trolls.

There was no leak with the stock bolt, so I'm really doubting that it's the O-Rings in the chamber. I'm not going to change the O-Rings yet so I can confirm or deny that the leak is coming from the Stopper-Bolt O-Ring and the cause is either a bad O-Ring or Baby Oil by replacing the lube with the Dye Stick Lube.

If it still leaks with the Dye Stick Lube, I will replace the Stopper-Bolt O-Ring and see if it does leak. If it does, then I will replace the rest of the O-Rings and test it further with different lubes.

But for now I need to test my theory before replacing the O-Rings because it will be hard to pinpoint where the actually leak is coming from. If I replace the O-Rings and apply new lube it will be hard to know whether it was fix by the lube, O-Ring replacement, Stopper-Bolt O-Ring replacement, etc.

What do you think? Suggestions welcome.

A systematic approach while eliminating variables is a good approach. It just takes a little more time and patience, but if you do it that you'll be able to pinpoint it.

Sounds like the small stem oring on the bolt stop is leaking through. You can either try dow33 or dow55... Preferably dow55 because it will "slightly" swell the oring in the process of keeping the oring soft and pliable.
