Took it apart today. Cleaned it up and fresh lube. 3-way still leaks. I have the delrin valve stem. Leak down the barrel stopped. Also got it back in time. Lubed the HPR also. Shot Mel an email with my replacement parts list to include, 3-way o-rings, valve o-rings, timing collar set screws, a No Rise feedneck (mine has the taller version), and a metal valve stem.
It will cycle, in time, right now, but every random shot the 3-way leaks out the front. Was not that dirty inside the lower tube. I reinstalled my hammer, dry.
