The PCV valve is easily checked with the engine running at normal idle speed (warmed up). Gently pinch the hose shut, then release it; the valve should click. If there is no click, check for plugged hoses or ports. If these are open, the valve is faulty. With the engine OFF, remove the valve from the engine. Shake it, listening for the rattle of the plunger inside the valve. If no rattle is heard, the plunger is jammed (probably with oil sludge) and should be replaced. Never operate the engine without the PCV valve or with the hose blocked.
Don't blow directly into the valve in an effort to free the plunger; petroleum vapors and deposits within the valve are harmful.
