BT4 Leaking out of barrel

[alexander001]

As stated above my BT4 has began to leak from the barrel when aired up?

Does anyone have a quick fix???

Thanks in advance

Is it leaking when cocked or just aired up ?

As soon as you slightly put the air in it begins to leak straight away and does not cock

its your valve try putting some gun oil int he asa gass up and fire a couple of times. If this doesn't work then take marker apart and dismatle your valve and reassemble.

ok i'll give it a go, thanks

As above, try changing all the o-rings ( there aren't that many ) and full clean and re-oil it...

I would say try to cock it before airing up, but 1. It's not recommended and B. If it won't cock, it won't... Perhaps the sear needs adjusting or replacing if it's worn to the point it can't be adjusted anymore...

O ring in the valve. Had same problem, if you have veen using a site bottle bet there is dirt or bit of bottle oring stuck in it

A leak down the barrel is the valve in the powertube. Cock it before gassing up. Also does it cycle with the leak?

The problem is still occurring (only just got round to it lol) the valve is perfect and there are no cracks/imperfections with the power tube, when i air it up slightly there is a leak down the barrel and when i screw it in further a repetitive rapid shooting noise occurs (as if the tank is out of air)

If you want me to provide a video it might shine a light on the situation for someone?

Is it not staying cocked when you gas it up ?
