This is the best pic I have of it. The PCV hose goes to the large vacum nipple on the carb base. My power brake booster hose goes to a nipple on my Indy dual plane intake. And yes I do use a nipple breather on the drivers valve cover. The hose just goes down by the frame as I did not want any oil to maybe spit out onto the valve cover when I race it since the PCV dont work at full throttle. So I use that hose to run any spitting oil when I race under the frame but it does not spit any oil as the hose is still dry. Its open of course so the PCV system pulls air through the crankcase. Ron
