turn your velocity down replace your power tube O ring and maybe a whole new parts kit

First thing you should do is if you took it apart, tell us. It will help alot in getting it working again, your just makeing it harder by denying it if you did.
Assuming you didn't mess with it:
If your using Co2 be sure that you are not getting liquid in the gun. IE turning angleing it so the tank is pointed down, using an antisphon on a remote, fireing long strings without adiquate protection.
Turn down your velocity. This should help with leaking out the back. If the velocity goes too high it will vent out the back, as a saftey feature.
Out of the barrel, that is either your PT o-ring or bolt stick. Take out the valve, remove the PT tip (small brass piece on very front of valve), under there is a spacer, take that out. Under that is an o-ring take out the o-ring, and replace, or inspect for and damage. If this doesn't help, try pushing the bolt back with a long spoon or something after the gun is gassed up, if the leak stops then it is bolt stick and you need a differant PT Spacer.
From the grip frame is your on-off remove the on-off, be sure it is properly assembled, and all o-rings are good.
Also oil your gun.
