This is my first Carbureted motor so I’m a little confused about some things. It’s the 85 5.2 318 and it js the stock 2 barrel carb on it. I want to dress the motor a little bit. I bought an Edelbrock 14 in universal air cleaner and ordered the Edelbrock valve cover that fit the motor. Question is, the current valve covers have a hose on the driver side cover that connects to the back of the Carb. I’m not sure if this is something that can be capped? The new valve covers each have one port in them. Neither of which look to be for that. Any tips tricks or information would be greatly appreciated.

Welcome.

You must keep those for a street engine. One side (the tube to carb) has a PCV valve, positive crankcase ventilation valve which draws out combustion gasses from the crankcase. The other side has a filter which allows fresh air to be drawn in.

If you don’t have a properly operating crankcase ventilation system the engine will get all gummed up and also have a positive pressure pushing oil out the seals and leaking.

Thanks! After I did some digging, I realized that it was the PVC Valve and I kind of figured the other was the breather. The stock air cleaner had hoses ran through it that connected to the breather, and a smaller one that goes to a T valve. If I take off the old air cleaner, can I bypass it by taking the T out and connecting the remaining hose?
