The only issue I have with the breathers in the valve cover is they make a mess all over the top of the engine. They will slobber oil no matter what you do to stop it. Depending on boost and rpm one blow by tube may not be enough and cause you to have tappet gasket issues. With the breathers the blow by has to travel from the crank case all the way up through the engine to get to the breathers picking up oil vapors on its way. I always run 2 blow by tubes and never have an issue. Just 2 cents
