Need A-5 help please

So i bought a tippmann a-5 and it had a horrable leak so i returned it and bought a new one, now here is the problem, this one also had a very faint leak you could barly hear it but got bigger and bigger untill it was very noisy. I was almost positive it was my valve so i ordered an o-ring kit and replaced the orings on the valve and the leak quited down but is still there and sometimes acts up on me still and becomes very noisy, also when i am low on air it spews it out of the barrell as a really noisy leak sound untill it gives off that machine gun sound and it is deff not supose to do that and wastes so much of my air im guessing anywhere from 20-60 shots! so here is my question to you, should i just buy a whole new valve? or will tippmann maybe send me a new one for free because im under a tippmann one year warentee? and has this happend to others?
