I bought an XValve from the fleabay a few months ago for a project and can't seem to figure out why the heck its leaking. When I got it, every o-ring was basically fossilized/falling apart so I replaced everything with fresh o-rings out of a new rebuild kit I bought from AGD (including the two o-rings on the reg valve pin). Replaced the bumper too since that was effectively melted.
It does have an ULT and the only thing I didn't replace was the tiny o-ring on the on/off pin (since I don't have one). The tiny ring is hard but its intact and seems to seat well. ULT has 3x shims on it.
I'm using it with a ULE body, minimag rail + sear + frame. Input pressure is around 850psi. Gun cycles just fine but has a steady leak from what sounds like the on/off (definitely coming from between the frame / rail and not down the barrel). Lvl 10 has 2x shims in the power tube and the medium/red spring.
Would the tiny ring on the ULT cause this (never had a valve with an ULT before this one)? I ordered a couple new tiny o-rings from AGD, hoping it'll solve the problem. Am I barking up the right tree?
