As a car owner, you may wonder what a PCV valve is, considering it is a part of your car engine you are not aware of. Your car’s engine is the lifeline of your car and has to be in its best shape every time. Every component of your car’s engine is essential to the overall functionality of your vehicle, and so is the “PCV” valve in your vehicle’s PCV system.
As a vehicle owner, you may or may not have heard about your car engine’s PCV valve, its essential role for your vehicle’s engine, and how to ensure its functionality.
This article explains what a “PCV” valve is, its position in your car’s engine, and how to ensure its functionality.
“PCV” stands for “positive crankcase ventilation.” A PCV valve is integral to the positive crankcase ventilation system (PCV) system. It is also known as the crankcase ventilation system.
Your vehicle’s crankcase holds your engine’s motor oil and is located at the bottom of your vehicle’s engine. The PCV valve is a one-way valve attached to the crankcase of your car’s engine and removes unwanted gases from the crankcase. It produces gases when your engine burns fuel.
A crankcase is an intrinsic component of an internal combustion engine and works mainly to store and circulate oil in the crankshaft.
These gases result from blow-by that occurs when fuel, oil, and exhaust vapors slip by the piston rings. All internal combustion engines produce blow-by gases.
The PCV valve performs the role of emission equipment and has several other benefits to a vehicle’s engine health.
The PCV system's goal is to re-route blow-by gases to the intake tract where they mix with fresh intake air and go through the combustion process again. Re-routing blow-by gases help reduce emissions, and the PCV valve serves as the emission outlet in a car’s engine.
The PCV system was actually among the first emissions control devices created in California in 1961. Within a few years, most new cars in the US featured the PCV system. The PCV system has become a standard worldwide on automotive engines today.
The PCV system was originally designed to allow the military craft to travel through water to help ensure a tight seal on the engine. However, the main purpose of a PCV today is to reduce harmful emissions. PCV systems also have the added benefit of improving oil life and keeping engine internals clean.
Ensuring the functionality of your PCV valve is essential for your engine’s health. When the PCV valve starts to malfunction, signs or symptoms will show to alert the car owner. Be sure to look out for symptoms of a damaged PCV valve. A bad PCV valve on an internal combustion engine includes oil leaks, seal and gasket failures, high engine oil consumption, and whistling sounds. Even though this is not an exhaustive list, these are some of the main symptoms of damaged PCV valves.
Unlike changing your battery or oil, there is no particular time frame to replace your PCV valve. As long as a PCV valve is functioning properly, you do not need to replace it. However, they are subject to damage due to a lot of blow-by gases traveling through them which can sludge the valve up. These blow-by gases flowing through your PCV valve leave traces of oil that can clog it up. Due to this, most manufacturers make them easy to access and replace.
Replacing the PCV valve on most engines is simple to do. You can replace a damaged PCV valve yourself or have a professional mechanic do that for you. To do this by yourself, first of all, locate the damaged PCV valve and disconnect the hose. Go ahead to twist the PCV counterclockwise and check the hose, clamps, and grommet in the PCV system. Look out for any other part that needs a replacement or is in poor shape. Finally, install the new PCV valve.
