It's not that bad of a job. you could just remove the valve and shake it. if you hear the valve rattling then it's still good. follow the steps below to help with removing it..the valve will look similar to the pic below..
Locate the valve cover (most often where the oil filler cap is located) and look for a plastic tube that runs from the valve cover to the intake manifold. Some vehicles may have the PCV valve located closer to the intake manifold side, but most are on the valve cover side of the tube.
Disconnect the tube from the PCV valve. The outlet connection of the valve is tapered and simply unplugs from the hose with some wiggling. Use the needle-nose pliers (gently) to assist in the wiggling motion to remove the hose from the PCV valve outlet.
Remove the PCV valve from the valve cover. The PCV valve sits into a rubber seat and can be pried out of position in the valve cover with some convincing. Often times, this can be done by hand, but use the needle-nose pliers (angled needle-nose pliers can be useful in hard-to-reach PCV valves) to wiggle it out of the rubber seat.
Clean the valve with carburetor cleaner or replace with a new one and reconnect by plugging it into the rubber seat, aligning the outlet connection, and reconnecting the rubber hose from the intake manifold.
