The PCV, commonly called a "breather" or "oil separator" valve, allows your vehicles crankcase to expel air and stop oil from escaping during the process. Common symptoms of failure can range from misfires, a rough idle, or a whistling noise. Replace your faulty PCV to keep your engine running at full potential.
