Can You Replace a Pcv Valve With a Breather

A PCV valve is a one way valve that allows air to flow into the engine while preventing oil and other fluids from escaping. A breather is a similar device, but it does not have a one way valve and instead relies on a filter to keep oil and other fluids out. Both devices are used to keep the engine running smoothly and prevent damage caused by excessive heat or pressure.

  • Remove the old PCV valve from the engine
  • Install the new PCV valve in the engine
  • Connect the new PCV valve to the breather hose
  • Start the engine and check for leaks

Can You Replace Pcv With Breather?

No, you cannot replace your PCV valve with a breather. Your PCV valve is responsible for recycling unspent combustion gases and keeping them from entering the atmosphere. A breather only allows fresh air into the engine to replace those unspent gases.

Does a Pcv Valve Need a Breather?

A PCV valve does not need a breather. A breather is only required if there is excessive blow-by, which is when combustion gases escape past the rings and into the crankcase. Excessive blow-by can cause the engine to run lean, so a breather helps to prevent this by allowing fresh air into the crankcase.

Is Crankcase Breather Same As Pcv?

A crankcase breather is a device that allows the pressure in the crankcase of an internal combustion engine to be released. The pressure in the crankcase is created by the up-and-down motion of the pistons as they move through the cylinders. This pressure can build up to dangerous levels, so the crankcase breather allows it to be released into the atmosphere.

The PCV (positive crankcase ventilation) system is designed to remove these fumes from the engine and prevent them from entering into the atmosphere. The PCV system does this by routing these fumes back into the intake manifold where they can be burned off by the engine.

What Happens When Pcv Valve is Removed?

If the PCV valve is removed, it can cause a number of problems. The most common problem is that the engine will run leaner because there is less air being drawn through the system. This can lead to piston damage and other engine-related issues.

Additionally, removal of the PCV valve can also cause oil leaks.

How to Install a PCV Delete

Pcv Valve Or Breather

Most people are familiar with the engine’s PCV valve. It is a small, round valve located near the top of the engine’s intake manifold. The PCV valve allows fresh air to enter the engine while simultaneously allowing exhaust gases to escape.

The PCV valve is an important part of the engine’s ventilation system and helps to keep the engine running smoothly. The breather is another vital component of the engine’s ventilation system. The breather is located on the side of the engine and its purpose is to allow air to enter the engine as it operates.

The breather helps to prevent harmful fumes from building up inside the engine bay and keeps the engine operating at a consistent temperature. Both the PCV valve and breather play an important role in keeping your engine running correctly. If either one of these components fails, it can cause serious damage to your engine.

Make sure to have them checked regularly by a qualified mechanic so that you can avoid any costly repairs down the road!

Pcv Valve Cover Breather

When it comes to your car’s engine, the PCV valve cover breather is an important piece of the puzzle. This small valve helps to regulate the pressure in the crankcase, and it also allows fresh air to enter. Without this valve, your engine would quickly become a very dirty and smelly place.

The PCV valve cover breather is located on the top of the engine, near the firewall. It is usually a small black plastic cap that unscrews easily. Inside this cap is a small metal disc with a hole in the center.

This hole allows air to flow into the crankcase as needed. Over time, this hole can become clogged with dirt and oil residue. When this happens, it can cause all sorts of problems for your engine.

The most common problem is that your engine will start to run Rough idling or stalling . You may also notice an increase in oil consumption or blow-by from your engine. If you suspect that your PCV valve cover breather is clogged, you can try cleaning it out yourself with some simple tools.

First, remove the cap and use a wire brush to clean off any build-up on the metal disc. If there is a lot of build-up, you may need to soak it in some carburetor cleaner overnight. Once it’s clean, put everything back together and see if that solves the problem.

If cleaning out the valve doesn’t help, then you may need to replace it entirely.

What Happens If You Remove Pcv Valve

If you remove the PCV valve from your vehicle, it will no longer be able to regulate the pressure in the crankcase. This can lead to a number of problems, including oil leaks, increased engine noise, and decreased fuel efficiency. In some cases, removing the PCV valve can also cause engine damage.

Can You Plug a Pcv Valve

A pcv valve is a pressure relief valve that is used to release pressure from the crankcase of an internal combustion engine. The pcv valve is typically located at the top of the engine, near the throttle body. The pcv valve allows air to flow into the crankcase, where it mixes with oil and vapors.

This mixture is then drawn back into the engine through the intake manifold.

The function of a pcv valve is essential for two reasons. First, it prevents build-up of pressure in the crankcase, which can lead to oil leaks.

Second, it helps to keep harmful vapors from entering the atmosphere. When these vapors mix with oxygen, they can form smog. Most modern engines are equipped with a pcv valve; however, some older models may not have one.

If your vehicle does not have a pcv valve, it’s important to have one installed by a qualified mechanic.


The post begins by asking if it is possible to replace a PCV valve with a breather. The author says that while it may be possible, it is not recommended. The reason for this is because the PCV valve helps to regulate the pressure in the engine and prevents oil from entering the combustion chamber.

If the PCV valve is removed, there is nothing to prevent oil from entering the combustion chamber and causing damage.
