I removed both 7 nipple vacuum valves and called my buddy who owns a machine shop. Tomorrow we'll re-surface the valve faces and then I'll reinstall them. HOWEVER, the one that comes out easily and comes apart with no rivet is on the Power module side. It installs on one side with a small bolt, and on the other it is held on by a clip, WHICH IS MISSING ON MY CAR. I am going to assume it is the same clip that is used on the Control Module side. Anybody got one? Happy to pay for it.
