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 |

What is the fonction of the line number 10 to the dizzy ? Yes, on the 74 cars there is a valve on the oil tower that connects to the #9 line. If this valve goes bad or is missing you will get as described, unwanted air entry after the throttle body. The later cars eliminated this valve in favor of a larger hose directly from the oil tower to the air cleaner. #10 line to the distributor retards the timing under high manifold vacuum |
