Understanding Valves And Why They Need Cleaning

Valves are critical components in your car’s engine. They control the flow of fuel and air to the combustion chamber and exhaust fumes to the exhaust system.

This is why it’s essential to clean valves regularly. Fortunately, you don’t have to remove the head to do this. There are several methods, such as using specialized cleaning agents or walnut blasting, to effectively clean your valves while they remain in place.

Regular valve cleaning ensures your engine runs smoothly, efficiently and prolongs its lifespan. Don’t neglect the valves when it comes to maintaining your car’s engine.
