I don't know where in the transfer port, I just know that's where I can hear the air coming out of, so it could be anywhere inside there.

So I just took the whole gun apart inspected everything and it looked perfect, including the valve seat o-ring…Like a new gun. I cleaned and lubed everything, put it back together and no leak???

One thing I did notice when I was disassembling the gun is that there is a screw on the back of the block, directly up from the rear of the grip on the right side. It is 4mm and it tightens both sides on the plenum tube. When I went to untighten it, the screw was very loose. Like wobbly loose! I'm wondering if that was not tightened down enough, it would keep the o-ring from sealing properly and that was causing the problem? If not, maybe one of the O-rings just needed cleaning and lube? I don't know but I'm happy, just a little frustrated too, not knowing what it was and if it will do it again tomorrow? You know what I'm saying? 

Like I thought, taking the gun apart was very simple and not nearly as scary as it looks. 

Thank you guys. I'd still like to hear anymore thoughts or ideas that might help me down the road. I'm worried I'll go to shoot tonight or tomorrow and have it happen again.
