Oil control valve commonly used on engine with variable valve timing system. This system is to control the engine performance using the method of retard and advance camshaft angle. And benefits of this system is: Fuel consumption efficiency, Reduce gas emission, and increase engine performance. For more information about oil control valve, please read full article below:
Basic Function Of Oil Control Valve
Oil control valve is controlled by the engine control module, or ECM. The oil control valve is basically what controls the flow of oil into the camshaft of the engine. This allows the internal moving parts of the engine to sustain their functionality. If the camshaft cannot be lubricated at the right times by the oil, then the engine won’t be able to perform its job properly. So, what the oil control valve does is opens and closes the camshaft at the appropriate times to let in oil when it is needed and prevent oil from entering when it is not needed. The ECM will control the valve and let it know what appropriate action it must take based on the engine’s performance demands.
Common Symptoms Of Failure Oil Control Valve
If you have oil control valve problems, then there are certain symptoms you can look out for. Some of them include slow acceleration, poor brake performance, and a strange burning smell in the car. Before it gets this bad, the computer in your vehicle should give you some warnings first on the dashboard. The most obvious warning will be when the “Check Engine” light is on. You may not know exactly why it’s on unless you experience those other symptoms mentioned before.
And also the fuel economy is what will be affected the most. Remember if the oil control valve doesn’t manage the flow of oil properly then it will cause the engine to overperform and use up more fuel. This means you’ll be spending more money on gas while causing your exhaust valves to open and close at the wrong time. Sooner or later, the internal components of your engine will get damaged as a result. That is why it is best to take care of these problems as soon as you notice them happening. It is a lot cheaper to change your oil or replace the oil control valve then it is to replace your engine.
Believe it or not, there are lots of people who forget to change their oil on time. The reason you need to change your oil every 3-6 months, or every 5,000 miles, is because debris and dirt build up in the oil after a while. If the oil does not get changed then it will create a blockage which will prevent the oil from flowing into the camshaft and will cause the oil control valve malfunction. So always remember to change your oil and keep it as clean as you can.
