I finally got most of the kinks worked out on the omega, realizing now that i am dealing with a vacuum leak at operating temp, im going to be replacing the intake manifold gasket and valve cover gaskets as well as rebuilding the rochester 2 jet that is currently on the car. That being said im not sure if the vacuum lines on the car are correctly installed to begin with being that i am the 3rd owner. Does anyone have a diagram or can explain accurately how the lines should be run? As well as how to bypass the egr system? Until i have the funds for the edelbrock 4 barrel inatke manifold that deletes the egr, i just want to get this thing running for now without stalling due to vacuum leak, i also am aware this is a vacuum leak as the brakes become very stiff indicating the booster is not functioning correctly, which was one of the first items on the car that i replaced, and it works correctly before the car gets warm.
