Is my reg leaking?
Is it normal to have lube coming out of this weep hole? New gun, less than 500 rounds through it. Air reservoir seems to hold pressure overnight. Or should i pull it apart and replace the seals on the reg?

Also, I am getting some weird chrony results toward the end of my shot string. The graph starts around 185 bar, and the peaks start happening slightly under 130 bar. Do you think this is from going off the regulator and could be tuned out? Or is it because it’s a new regulator and needs to be broken in further?

No its not leaking, it is just the atmospheric breather hole for the Belleville washer stack which has excessive factory grease on them.. the grease finds its way out 🙂
If the reg was leaking from either of it O rings it would get a constant leak from that little vent hole.. test it with a spit bubble..
