Running seafoam through the PVC hose really helped mine out. Just did mine thru the PCV but from my understanding if you run it through the oil it is highly recommended that you do an oil change soon after..
How long do PCV valves last?
There is no specific lifespan for your car’s PCV valve. It lasts as long as it lasts. Regular maintenance will help provide a longer use life, while neglecting your regular oil changes will shorten it. Ideally, the PCV valve should be changed with every major scheduled service (30, 60, 90K, etc.).
How do you know if you need a new PCV valve?
One of the most obvious warning signs your PCV valve may need replacing is smoke coming out of the tailpipe or excessive oil consumption. If the PCV valve is stuck in the open position, it will draw excess vapors from the crankcase and burn more oil than expected.
What happens if PCV valve is disconnected?
If a car runs better with the PCV valve unplugged, the valve is likely not working properly and requires replacement. The unplugged valve allows the exhaust gases to vent through the valve opening, which reduces pressure in the engine from the exhaust gases.

Why is my Equinox burning oil?
That lawsuit alleges the engine’s piston rings fail to maintain sufficient tension to keep oil in the crankcase, allowing the oil to sneak past the rings and into the combustion chamber. The oil burn issue can also apparently foul the spark plugs and lead to carbon buildup on the pistons and cylinder walls.
Does a Chevy Equinox have a PCV valve?
The Best in Auto Repair
The average cost for a Chevrolet Equinox PCV valve replacement is between $50 and $59. Labor costs are estimated between $34 and $43 while parts are priced at $16. This range does not include taxes and fees, and does not factor in your specific model year or unique location.
Can PCV cause poor acceleration?
A faulty PCV valve can cause a faulty lean/rich mixture to be formed, which can cause misfires on both idle and acceleration.
Which oil is better 5w30 or 10w30?
5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.
Can PCV cause high idle? A faulty positive crankcase ventilation (PCV) valve may also cause an unusual high idle speed. This is similar to a vacuum leak, since the PCV valve routes crankcase gases into the intake manifold where they combine with the air fuel mixture.
Can a bad PCV valve cause a car not to start? A fuel mixture that is too lean to start the engine can also be caused by dirty fuel injectors or a large vacuum leak (PCV valve, EGR valve, any vacuum hose on the engine or the intake manifold gaskets). Vacuum leaks have the most effect on the idle mixture, which you can see with a scan tool by looking at fuel trim.
Can a bad PCV valve cause blue smoke? If the PCV valve failed, it would essentially keep mixing the engine oil with air and gases inside the engine. And the vehicle would emit blue smoke from the exhaust upon combustion of this mixture. A bad PCV valve could cause major engine trouble if ignored.
Can a clogged 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 PCV valve cause white smoke?
A faulty PCV valve can cause a rich or lean mixture to form in the engine, which can cause symptoms such as white or black smoke coming out of the exhaust pipe, depending on what type of mixture problem the engine is experiencing.
What are the three signs of a bad PCV valve?
Common signs of a faulty PCV valve include excessive oil consumption, oil leaking, a blocked breather filter, and reduction in overall performance.
Can I drive without PCV valve?
What Happens If You Run A Car Without A Pcv Valve? Rubber hoses are used to attach PCV valves to intake manifolds. You will not be able to attach the hose to the engine if you remove the PCV valve, and there will be a massive leak of air into the engine. Your engine will run rough or die as a result of the intake leak.
Can a bad PCV valve cause white smoke?
A faulty PCV valve can cause a rich or lean mixture to form in the engine, which can cause symptoms such as white or black smoke coming out of the exhaust pipe, depending on what type of mixture problem the engine is experiencing.
Where does the hose from the PCV valve go?
A hose connects the top of the PCV valve to a vacuum port on the throttle body, carburetor or intake manifold. This allows the vapors to be siphoned directly into the engine without gumming up the throttle body or carburetor.
Does a bad PCV valve affect performance?
PCV valves play an important role in the vehicle, so a faulty valve might affect the overall performance. An engine that has a bad PCV valve might not close properly, allowing extra air into the intake, which can result in erratic idle and engine performance issues.
Does a PCV valve affect performance? Because the PCV valve controls the airflow between the crankcase and the intake manifold, a broken PCV valve can have the same symptoms as an intake air leak, which can cause the idle RPM to get too high and other strange idle behaviors like very rough idle.
