Suppose I should have mentioned that I edited my very first post for easy of finding it. Guess it wasn't that easy

Any who: Had one bad check valve. Replaced both with a generic Doorman one way check valves. Rebuilt the vacuum harness in the engine bay with a decent quality rubber line and new t-fittings. Broken vacuum lines on the CAD were also a problem. Eliminated the vacuum lines in the system and added a Posi-Lok kit. That combination of things have got the vents working like they should.
