  1. 1976 Eldo vacuum question

    Cadillac Seville / Cadillac Eldorado Forum
    First time posting! Bought a 76 that wouldn’t pass smog, rebuilt the carb and replaced most of ignition system now she runs great. My question is the two vacuum ports in the air cleaner, one has a green valve and the other is completely open. When I cap it the motor runs and idles much better...
  2. 1968 Eldorado - Hydroboost to Vacuum conversion available?

    Cadillac Seville / Cadillac Eldorado Forum
    Good day! My 1968 is a hydraulic fluid mess and I want to convert the brake booster to a regular vacuum booster and have less hydraulic lines going trough the engine bay. Is there any direct bolt on conversion or has anybody attempted this in the past? Thanks
