Breather Question

Hello, Everyone!

I had a quick question. On my Drivers side valve cover, there is a PCV going to the front of my carb, and on the passenger side valve cover there is a plumber's plug in the hole where the breather is supposed to be. So, my question is, Should I put a breather there, or is it perfectly fine plugged? From what I've seen, you "should" have ventilation on each side. Thanks!

Re: Breather Question

I think you need the crankcase breather hose going from the valve cover to the air cleaner breather element in order for the PCV system to operate properly. I just spent $43 to get the proper vent hose for my 83. Here are pics of it, but I have a big block.
