Leak

[Woogie12]

I have a leak coming out of the bolt in my classic valve with level 10. Sometimes it's a very small leak and only happens when I pull the trigger, sometimes when I am not putting pressure on the trigger it leaks, and sometimes it leaks pretty badly all the time. I have tried adding and removing shims and oiling but they haven't helped and the leak is getting progressively worse. Any ideas?

I'm on the smallest carrier but the leak does change tone when I push something against it.

Perhaps the o-ring is screwed?
