Somebody explain how a hole in the intake can be uses as a PVC port. The intake manifold sees intake air and exhaust gases seperated by the ports in the mainfold. The valve covers see the crancase gases. Does the hole in the intake have a passage tied to the top of the head? True the splash sheilds will prevent
oil from escaping but do nothing as far as the fumes escaping from the breathers. In all honesty KC should have added the baffles to the valve covers, especially since it is such a high end motor.
