My car idle is fine. What other symptoms of a failing PVC?

Thanks for the advice
PCV Valve = Positive crankcase ventilation valve

On our cars, you have probably heard it referred to the crankcase vent valve (CCV) or oil separator. You don't need to replace till you have a problem and those include excessive burning of oil and/or leaks down the lower driver's side of the engine compartment.
