Nice, picked up a 4200 second hand and have been slowly diagnosing issue after issue, it's almost there but I'm getting a lot of air in my line with similar results. I did have my pressure relieve valve fly across the room with some oil behind it, I'll double check how it's in there, probably going to tear it apart and redo all the seals, double check the servo adjustments and go from there, thanks all!
