Okay guys. How important is a pcv valve? Do I really need it or can I just run 2 breathers? Hooked mine up today and the car seemed a bit off. I'm not sure if maybe it's got a vacuum leak around my barb fitting maybe or what. What do you non ls fellas run?
You need a PCV valve or your going to have cc pressure working on pushing oil past your seals and gaskets. I run a breather on each bank with PCV valve. I was talking about the color on your parts car - same as mine.
