past week i was making 7psi then it dropped to 5psi the next day. this weekend i popped the hood and got after it. found out that the PCV valve seat/seal was gone and was blowing 4PSI of my boost into the crank case and blew alot of oil into the blower out the other valve cover vent line. so i decided to eliminate the problem and T both sides together and add a filter. have seen no problems from others who have done this on these modular engines. runs much better now. and also raised my idle 300 rpm and it go rid of my Idle surge issue. except when i go from D to park and it flakes out. but i think neal and fix that with his tuning mastery!
