Does a bad PCV valve affect performance?
Overall poor performance As the PCV valve starts going bad, the performance of your vehicle will get worse. This can be exhibited by a buildup of pressure in the exhaust or the engine could stall out. The bad PCV valve may not close all the way, so oxygen may get into the combustion chamber.
Can PCV valve cause rough idle?
a faulty pcv valve can cause a number of problems: 1. rough idle or stalling: if the plunger is stuck open, the pcv valve will allow too much air to enter the engine. this can cause a lean air-fuel mixture, resulting in a rough idle or stalling.
Can a PCV valve cause misfire?
Another symptom of a bad or failing PCV valve hose is your vehicle will misfire while it is idling. This can be from a loss of vacuum due to the hose not working properly because of a leak, the hose being pinched, or becoming clogged from buildup over time.
Where is the PCV valve located?
PCV Valve Location. The PCV Valve is often located on the valve cover, on the engine’s top, but it can also be on a hose between the valve cover and the air intake filter. Just follow the hose on the top of the car engine, and you will find the PCV valve. Some cars do also have an integrated PCV valve with the valve cover.
What is a PCV Valve?
PCV valve stands for Positive Crankcase Ventilation, and it is one of the oldest and most used emission devices in many vehicles. The PCV valve function is to eliminate crankcase emissions from the crankcase and send them to the intake. Therefore, they combust them again in another engine cycle, making the engine’s emissions cleaner and more effective.
What does it mean when your PCV valve is faulty?
If the PCV valve is faulty and causing a rich or lean mixture to the engine, you can get symptoms like white or black smoke coming out from the exhaust pipe, depending on what type of mixture problem the engine has. A short conclusion is: If you see any strange smoke from the exhaust pipe, make sure that the PCV valve is in good shape.
What happens when you have a faulty PCV valve?
When you have a faulty PCV valve, causing a wrong fuel mixture, you can feel that your car has rough acceleration on high and low RPMs. On most cars, you won’t feel a broken PCV valve on higher RPMs than idle, but it’s worth mentioning because it can happen depending on the valve’s design.
Why does my PCV valve feel like it's bad?
Because you can get a faulty lean/rich mixture due to a faulty PCV valve, you can feel misfires on both idle or acceleration when your PCV valve is bad. If you have a too lean mixture, the cylinders won’t fire up correctly, which can cause misfires.
How long does a PCV valve last?

How does filtered fresh air enter the valve cover?
Filtered fresh air enters the valve cover on the side through 610 & 210 in the diagram . This is the clean side. It is the filtered fresh air metered by the MAF sensor (for proper A/F ratio so the ECU can command the proper cylinder fill rates and injector duty/pulses, etc.) into one valve cover where it is drawn past the valve train assembly, into the main crankcase, where it flushes the damaging combustion byproducts through and out the opposite heads valve train and out the dirty side (contaminated side) through 242. This is then (through the intake manifold vacuum) mixed with the intake air charge and burned in the combustion chamber and further in the catalytic converter. The problem we are correcting/curing is separating the oil vapors from these combustion byproducts so the oil is not causing the coking and detonation that degrades the power and economy and engine life.
