Review on 🔧 Dorman 47079 PCV Valve Elbow - Optimal for Dodge and Jeep Models by Anthony Lopez

This elbow is for the FRONT of Jeep 4.0L with CCV (Non-PCV) engine. I have a 2000 Cherokee 4.0L. This engine is CCV, not PCV. The rear low flow manifold and the front high flow manifold are the FRONT MANIFOLD leading to the intake box. A small flow is sucked in from the intake manifold. It is very important that these two parameters are correct, otherwise you may end up getting too much pressure or diverting a lot of flow into the manifold and air intake. See the attached picture for a better idea. The front knee is this part: http://www.amazon.com/gp/product/B000JZI1U2/ You can see the difference as it (47057) has a small hole at the bottom. This article in question (47079) is wide open and has no borders. Finally, if you replace it, spend the extra money and get a jack. http://www.amazon.com/gp/product/B000C5I49C/
