HI Group, I have seen many PVC valve arrangements. On the 235 inline 6. On the valve cover to air filter or old vacuum line where wipers went and crank case to filter and or old vacuum line where wipers went. Which one is the best for the engine. Sucking from crank case or top of valve cover and where is the best place to have it go, air filter or old vac line of wipers?
Hope to get the best one for the engine
