If you're not seeing orings then you know exactly the source of the problem. Another problem is you're running co2, which freezes orings of every kind. FOR GOD'S SAKE MAN IF YOU'VE GOT THE MONEY TO BUY AN EVOLUTION COCKER RUN IT WITH NITROGEN AND A DECENT REGULATOR!!!!! People that run any gun over $200 other than a Shocker or Impulse and don't use nitrogen should be taken out and slapped in the face with a very large wood plank. Also, either replace the 3 way orings or get a new 3way altogether and get a new timing rod.
