Once you've located your PCV valve, you need to get it out. First, remove the hose that is connected to the top of the valve. If your valve is installed between two hoses, you will be able to pull the valve out. If your PCV valve is installed directly into the crankcase or valve cover, grasp it firmly with your needle nose pliers and pull it out. It should come out with a little oomph.
