O.K so I just got my new weber 34`s for my 1.7. I installed them and started the car. Prior to this I installed a new fuel filter and fuel line. The other line was cracking and sort of scary. So my question is related to vacum. It looks like the intakes were made for an advance. They have a port on them so do I just plug it. Also at the bottom of the carb itself there is also some sort of port.My last question is some parts that were missing when I got the car. On the oil fill cap port there is a small elbow coming off of it. It looks like a PCV valve would go there or something but I have nothing. And on the engine block there is another port. Look at the pics and hopefully some one can help. I think the car is close to running but I want to make sure what these are for. Thanks Joe.

Joe,
I'd recommend the following; 1. Take a vacuum tube and connect the left and right bank manifods on that port. 2. Buy a breather box with at least 3 ports. Check for ports on the top of the heads above the valve cover and if there run hoses from those ports as well as the oil filler port to the input side (lower) of the breather box. Run the output to the carb airfilters. 3. If you have a vacuum advance dist, use one of the vacuum ports on the carb for it. If not, cap both carb vacuum ports 4. Drive the car and resync the carbs a few times. Hope that helps. |

I will get a breather box and install it.Thanks for your help. |
