Sorry to jack your thread but I could use some help with blow by on my dads 347...given it's in a fox so the valve covers dont have multiple hook ups. I just have the catch can being run directly between the PCV lines. Do it would go PCV (back of lower intake), hose to catch can, Catch can, hose to hook up on Holley Systemax upper. I kept the line that runs from the valve cover to the TB as well. Well I ran his car and could tell the catch can was getting some oil but upon inspection after cool down, this was after a short short drive, I still had a puddle of oil sitting in the CAI. What else can I do?
