Symptoms of a Stuck Closed PCV Valve or System

- Failure of one or more oil seals or gaskets.
- Engine oil leaks.
- Low whistling or moaning noise.
- Moisture and sludge buildup inside the engine.
- Engine surges.
- MAF sensor trouble code.
- P0171 or P0174 trouble codes.
What happens when PCV valve fails?
Whenever your PCV valve fails, its plunger may remain open. An abnormally large volume of air will enter the combustion cylinders when this occurs. This results in a lean air/fuel mixture since there’s more air inside the cylinders than fuel. As a consequence, your engine could stall or idle poorly.

What happens if a PCV valve is stuck open?
It forces oil past the engine’s seals and gaskets. A stuck open PCV valve or leaking hose results in a large vacuum leak, a rough idle, and drivability issues like surging. A closed or tarnished PCV valve can cause engine oil to back up into the breather.
What problems does a bad PCV valve cause?
you have a bad PCV valve are rough idles and a lean air to fuel mixture. These two problems cause an issue with the air intake due to the bad PCV valve. Many of the symptoms of a faulty PCV valveare the same as an intake air leak.
