What parts do I need for my engine variable valve timing (VVT) oil control valve replacement?

You can check your owner’s manual or ask a mechanic for your vehicle’s exact required parts, but here’s a general rundown:

Variable valve timing (VVT) oil control valve: The VVT oil control valve controls oil flow to the variable valve timing system, which adjusts the engine’s intake or exhaust valve timing. This is the main part of the replacement, and it typically costs $50 to $200.

Engine oil: Your engine oil may need to be replaced after a VVT oil control valve replacement. Use your owner’s manual to select the correct manufacturer-recommended oil for your engine. Depending on the vehicle, engine type, and recommended oil grade, engine oil can cost $35 to $75.

Gasket or seal: The VVT oil control valve is usually connected to the engine by a gasket or seal that prevents oil leaks. When changing your VVT oil control valve, your mechanic may also change the gasket or seal. Gaskets and seals usually cost $20 to $30.

Lithium grease: Lithium grease is used on the VVT solenoid to securely seal it to the engine. On average, lithium grease costs $25.

You can buy Engine Variable Valve Timing (VVT) Oil Control Valve parts for your car from auto parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, as well as online retailers such as Amazon and RockAuto.

How will a mechanic replace my variable valve timing (VVT) oil control valve?

If your vehicle’s variable valve timing (VVT) oil control valve is not optimally functioning, you’ll need to take your car to a certified mechanic for a replacement. Your mechanic will run a diagnostic test to identify issues with the VVT oil control valve or VVT solenoid, and then replace it with these steps:

Preparation: Your mechanic will turn your car off, disconnect your car battery, and remove your engine cover.

Finding the VVT oil control valve: The exact location of your VVT oil control valve will depend on your vehicle’s make and model, but it’s typically found at the front of the engine near the cylinder head.

Removing engine parts: For some vehicles, the mechanic may remove engine parts like the air intake duct to gain better access to the VVT oil control valve. If parts are moved or removed, your mechanic will mark their initial positions to ensure they’re placed back correctly.

Disconnecting electrical components: The mechanic will carefully disconnect the VVT oil control valve from any electrical components.

Removing the old VVT oil control valve: Your mechanic may need to unscrew or remove bolts or clips from the VVT oil control valve to remove it from its mounting position. Once the VVT oil control valve is loose, the mechanic will remove the part and any debris left behind from the old component.

Installing the new VVT oil control valve: The mechanic will lubricate the VVT oil control valve and apply lithium grease to the solenoid spool seals, and then fasten it in its designated position using the appropriate mounting hardware.

Reconnecting and replacing: The mechanic will reconnect any electrical components that connect to the new VVT oil control valve. The vehicle’s battery will also be reconnected, and your mechanic may facilitate an oil change if necessary.

Testing: Once the new VVT oil control valve is installed, the mechanic will run a few tests to confirm that the VVT system is functioning properly. They may use an OBD-II diagnostic scanner to check for any diagnostic trouble codes (DTCs) related to the VVT system. The mechanic’s tests will ensure that the valve is communicating effectively with the vehicle's engine control module.

What happens if I don’t replace my variable valve timing (VVT) oil control valve?

A faulty variable valve timing (VVT) oil control valve can lead to serious issues if not replaced:

Poor engine performance

Engine misfires

Reduced power

Rough idling

Lower fuel efficiency

Higher emissions

Engine damage

Hesitation during acceleration

Rough automatic shifting

Inconsistent speed

What is a variable valve timing (VVT) oil control valve?

The variable valve timing (VVT) oil control valve is a part of the VVT system in your engine. The VVT system adjusts the timing of your engine’s intake or exhaust valves, and the VVT oil control valve controls the engine oil’s flow to a VVT actuator. This process improves engine performance, increases fuel efficiency, and lowers emissions from your vehicle’s combustion process.

When should I replace the variable valve timing (VVT) oil control valve on my car?

The most common symptoms of a bad oil control valve include:

Check engine light: If there is something wrong with your VVT oil control valve, your engine control unit (ECU) or powertrain control module (PCM) will detect it. If detected, your VVT oil control valve issue will cause your check engine light to illuminate on your dashboard.

Engine misfiring: A malfunctioning VVT oil control valve will throw off your valve timing, which can lead to engine misfires.

Reduced power and performance: Incorrect valve timing from a bad VVT oil control valve can reduce your vehicle’s power and performance. Performance issues will be especially obvious when you attempt to accelerate, or when you’re driving at low RPMs.

Acceleration issues: If your VVT oil control valve is malfunctioning, you may experience trouble acceleration. Your car may hesitate or jerk when you apply pressure to the gas pedal.

Rough idling: You may feel instability or vibrations coming from your car’s engine while idling if your VVT oil control valve is damaged or malfunctioning.

Higher emissions: A problem with the VVT system increases your vehicle’s emissions. Note that if your emissions are higher due to a faulty VVT oil control valve, you will not pass an emissions test, which is usually required for registering your car.

Lower fuel efficiency: A faulty VVT oil control valve can cause increased fuel consumption, which will reduce your gas mileage and fuel efficiency.

Engine noises: If your VVT oil control valve is faulty, you may hear a knocking noise coming from the engine’s cylinders. A pinging sound is also common for improper valve timing.

Car won’t start: You may experience difficulty starting your car if your VVT oil control valve is damaged.

How often should a variable valve timing (VVT) oil control valve be replaced?

Unlike other vehicle components that require regular maintenance and replacements, there is no replacement interval for a VVT oil control valve. Instead, VVT oil control valves should be replaced in cases of damage.

Regularly check the state of your VVT oil control valve to ensure it is functioning normally. A damaged VVT oil control valve can affect the longevity and performance of your engine.

Can I replace my variable valve timing (VVT) oil control valve myself?

You may be able to replace your variable valve timing (VVT) oil control valve yourself, but the replacement process is slightly complex and requires a fair and comprehensive understanding of your vehicle’s engine. It’s best to skip the DIY auto repair and take your car to a certified mechanic if you need your variable valve timing (VVT) oil control valve replaced.

What happens if you don't replace VVT?

Engine damage

Poor engine performance

Engine misfires

Hesitation during acceleration

Reduced power

Rough idling

Lower fuel efficiency

Higher emissions

Rough automatic shifting

Inconsistent speed

Can you drive with broken VVT solenoid?

The variable valve timing solenoid and variable valve timing oil control valve play crucial roles in the operation of your vehicle’s engine. While you can drive with a broken VVT solenoid, your car will not run at its optimal functioning level.

Avoid driving and take your vehicle to a professional mechanic for a diagnosis as soon as possible if you suspect issues with your variable valve timing system.

Is the oil control valve the same as VVT?

Your oil control valve is a main component in your vehicle’s variable valve timing system. The VVT system features a VVT actuator (sometimes called a VVT phaser) and an oil control valve. These two parts work together to enhance the engine’s valve timing, improve fuel economy, decrease emissions, and optimize the vehicle’s performance.
