im not running a pcv valve its open,i have a breather on the other side. i can see the valve seals, when i pull the intake,the silicone around the ports are flat ,on the intake side,but under the valley pan its leaking/sucking under the ports and leaving a visible sign at the lower sectionson top of the valley pan ,that i cant see with the intake on the engine.rocker shafts are on correct,crane gold race rockers ,new hardened shafts ,checked a few times to make sure. ports were supposed to be done,ported.
