Your car's engine needs quality PCV valve to continue in its efficient function. Ensure your car's efficient performance with a top-notch PCV valve.
Engine combustion creates tremendous amounts of energy from the pressurized mixture of air and fuel. But did you know that the engine produces more power than it actually uses? The excess power comes out in the form of exhaust gases. These by-products are actually wasted energy from combustion. If these wastes remain in the engine, it will clog the parts and compromise overall performance. That's why the PCV Valve (Positive Crankcase Ventilation valve) is an important component of your car.
This valve serves as a vent for the upper engine. It prevents unwanted by-products from re-entering from the internal combustion system. It also separates the unwanted by-products from the combustion chamber. After that, the valve funnels the by-products to the exhaust system, where they are guided out of your car through a series of pipes. If it fails, the by-products accumulate in the crankcase, causing your engine to become overworked and worn out.
You can easily diagnose if your PCV Valve is malfunctioning. The first thing to look for is an indication of a malfunctioning air intake system. When the valve is broken, dirt build-ups in your air filter will make your car's fuel consumption inefficient. If that's the case, you should get a PCV valve replacement as soon as possible. Replacements are not expensive, and they can be easily installed. In choosing a replacement, make sure it fits your car specifications and passes OEM standards.
Important Facts You Need to Know About PCV Valve
Like the exhaust manifold, the positive crankcase ventilation (PCV) valve is an important part of your vehicle's exhaust system. So how does the PCV valve work? Engine operations usually generate a considerable amount of high-pressure combustion gases. Piston rings prevent these gases from leaking into the crankcase. These vapors contain moisture, combustion by-products, and unburned fuel vapors. To prevent these gases from building up sludge in the crankcase, the PCV valve draws and directs them into the intake manifold. The intake manifold then allows these gases to be re-burned in the engine's cylinders. Given their functions, PCV valves are usually designed to withstand high pressure and temperature. But just like other exhaust components, the PCV valve will periodically wear out. Good thing, you can easily and conveniently get the best replacement by shopping here at CarParts.com.
• Keeps combustion gases from accumulating in the crankcase
• Prevents moisture that can cause sludge buildup
• Reduces harmful exhaust emissions
Some Important Things to Remember When Buying a PCV Valve for Your Car
The positive crankcase ventilation (PCV) valve is a part of your car's emission system whose main function is to draw out the blow-by gases from the crankcase and send it back into the combustion chamber where it can be burned again. Additionally, the PCV valve also keeps the oil from leaking out and causing sludge. It may be considered as one of the simplest automotive components, but it's still capable of providing chock-full of benefits to your car's performance and the environment. If you're on the look-out for a new PCV valve for your vehicle, here are some of the dos and don'ts to help you pick the right one out:
- Make sure that the size of the PCV valve exactly matches the dimensions of the one you're going to replace. Keep in mind that installing an incorrectly-sized PCV valve may result to improper air flow, which can negatively affect your vehicle's performance.
- Double-check if the flow rate of the PCV valve meets the requirements of your vehicle's engine. Although these components look similar to each other, you shouldn't forget that each of them is rated differently for a specific application.
- Know which type of PCV valve would best suit your car's needs. Consider buying a heated valve if you live in a cold area. Although a lot more costly, this type can effectively prevent freezing problems.
- Ensure that the PCV valve grommet or o-ring attachment is made from high-quality material. Although this component may seem inconsequential, you should bear in mind that this is usually the root of most PCV valve failures.
- Buy an OEM PCV valve instead of going for aftermarket ones to ensure that it fits properly. Aside from compatibility, the quality and reliability of an OEM valve is also better guaranteed.
- DON'T sacrifice quality for the sake of getting a cheap deal. As much as possible, buy an aftermarket PCV valve from well-known brands.
- DON'T forget to inspect the inlet and outlet hoses to see if they need to be replaced as well. It's a good rule of thumb to install new ones along with the PCV valve to ensure that the entire system works properly.
- DON'T settle for a used PCV valve without thoroughly checking if it's in good condition. Make sure that it meets the specifications required by your vehicle.
How to Replace Your Vehicle’s PCV Valve in a Few Easy Steps
The PCV valve basically lessens your vehicle's harmful emissions by feeding the hydrocarbon vapor from the crankcase back into the intake manifold. This component is highly susceptible to clogging, and once it gets plugged up, your engine may have a hard time working properly because of an incorrect oil flow. Stalling and oil leakage are the two infamous indications of this dilemma. Since the PCV valve directly affects your vehicle's engine, it's absolutely important that you replace it once it gets damaged or reaches the manufacturer-recommended replacement schedule. With the right tools and mechanical know-how, you'll be able to perform this as a DIY task. Simply follow the steps below and you'll get this done in jiffy:
Difficulty level: Easy
Tools that you'll need:
- Needle- and angled-nose pliers
- PCV valve replacement
- Ratchet and socket set
- Owner's manual
Step 1: Locate the PCV valve by looking for the valve cover or the plastic tube that's connected to the intake manifold. You may refer to the owner's manual to easily find out where it's located.
Step 2: Using your needle-nose pliers, unplug the plastic tube from the PCV bulb. Remember to work gently to avoid damaging the tube.
Step 3: With your hands, carefully remove the PCV valve from the grommet. If it's hard to do this by hand, you can just use your needle pliers to pry it off. You can also use the angle-nose pliers if the PCV valve is located on an area that's not easily accessible.
Step 4: Before installing the new valve, thoroughly check the condition of the grommet and the plastic tube first. This is to ensure that these components are replaced immediately if they're not in good condition.
Step 5: Take the new PCV valve and put it over the place where you removed the old one earlier. Push down on it firmly until it's securely placed on the rubber grommet.
Step 6: Reconnect the plastic tubes you detached earlier. Make sure all components are properly secured to avoid oil leakage.
The entire task of replacing a PCV valve may take a beginner DIYer around one hour to finish. For expert mechanics, this procedure may be done in just half an hour. Remember to observe proper safety precautions.
