The Honda PCV Valve is located in the Honda CRV 2012

The PCV valve is found in a gas/petrol engine.You probably don't know how important this part is to the engine.Most different petrol engine manufacturers have a problem with this little piece.

Plastic hoses with a spring make up most of the PCV valves.When the PCV valve fails, you will get a lot of symptoms from it, because it wears out in a hot place like the engine bay.

Everything you need to know about the PCV valve is contained in this article.There are symptoms of a bad PCV valve.

The check engine light is often a symptom of a faulty PCV valve in modern cars.There is a trouble code in the engine control module.

If you want to read the trouble code from the engine control unit, you have to use an OBD2 scanner.Older cars with a PCV valve fitted without an electronically controlled engine will not have this symptom.

A broken PCV valve can have the same symptoms as an intake air leak, which can cause the idle to get too high and other strange idle behaviors.

A faulty PCV valve can have the same symptoms as an intake leak, and the air/fuel mixture can end up being wrong, because of the issues discussed.You can feel the same symptoms as from a lean mixture if your air/fuel mixture becomes lean.

You can often see that the car is rich in mixture and that it has a smell of petrol and gray smoke.

When your PCV valve is bad, you can feel misfires on both engines.

The cylinders won't fire up correctly if you have a too lean mixture.You can turn off the spark with the fuel if you have a mixture that is too rich.

If you have a faulty PCV valve, you can feel that your car has rough acceleration on high and lowrpms.

On most cars, you won't feel a broken PCV valve, but it can happen depending on the valve's design.

If the PCV valve or the hoses are blocked, you will get a very high pressure inside the engine crankcase, which will push the pressure up in the cylinders and out from the gasket.

If you suddenly see several large oil leaks and increased oil consumption in your car, check the PCV valve and the hoses to it to make sure they are not blocked.

If the PCV valve or the hoses are blocked, the crankcase will push up oil into the combustion chambers, which will cause oil to burn inside the engine and go out through the exhaust pipe.

There will be a lot of smoke from the exhaust pipe.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.

If you see smoke coming from the exhaust pipe, make sure the PCV valve is in good shape.

One of the oldest and most used emission devices in many vehicles is the PCV valve.The PCV valve is used to send emissions from the crankcase to the intake.The emissions of the engine are cleaner and more effective when they combust them again.

Most PCV valves are made the same way, with two hosing connections and a spring-loaded one-way valve inside.When the engine is not running, there is a lot of vacuum in the intake manifolds, which helps the emissions get sucked out from the crankcase at lower speeds.

When your engine is revved up and you drive on higher RPMs, the PCV valve will open further and suck out more air from the engine's crankcase.

If you have a turbocharged engine, you don't want to boost pressure into the crankcase, which will cause oil leaks and blow gasket.It is important to have a one-way PCV valve.

The PCV valve only works on low RPMs and is designed differently.Some PCV valves have electric vacuum solenoids that can be used to control them.We will discuss them in another article.

There are some trouble codes with a faulty PCV valve.It is probably time to check the PCV valve if you experience any of these trouble codes.

It is not 100% that the PCV valve is broken just because you see trouble codes.These codes can be other things, and I always recommend you to check out the parts before you replace them.

The PCV Valve can be found on the engine's top, but it can also be on a hose between the valve cover and the air intake filter.

You can find the PCV valve by following the hose on the top of the car engine.Some cars have an integrated PCV valve.

A PCV Valve costs between 20 and 50 dollars.The cost of labor at a mechanic workshop can be as high as 200 dollars.A PCV Valve replacement will cost between 50$ and 250$.

Depending on the engine and car you have, the replacement cost of a faulty PCV valve can be vastly different.The PCV valve's price is often meager, and you can expect prices of around $20-50 for a brand new valve.
