Hello from paris France,
would like to learn about air lines and vaccum on my 914 2.0 GA 1974. I do not understand why the oil vaccum breather is pluged after the buterfly with a dizzy line and the valve for deceleration additional air. Thanks for your help CheeRS |

Just run the vacuum retard hose as per the diagram as the distributor is a mechanical advance unit (the weights are inside) and you would need a port on the throttle body to plug in the advance hose thats above the throttle plate. The PCV is positive crankcase ventilation valve to suck the pressure out of the crankcase. If this isn't connected then the crankcase pressure has nowhere to go and gaskets and seals can leak, mostly the valve cover gaskkets. |
