DA, I'm at home, been here for 3 hr. just enjoying a couple of cold ones before making dinner. Actually working on a custom rt rail. My way of unwinding.
when you change carrier o-rings, you have to go through the adjustment process again of finding the largest carrier that doesn't leak.
1) 3 drops of oil into valve. Could be a dry oring.
2) REPLACE powertube oring. If that doesn't help...
3) add in shim to the carrier if not
