What is the function of an oil cooler bypass valve?
The bypass valve – otherwise known as a pressure relief valve – is an integral part of the oil filter. The valve is designed to open when the oil filter becomes clogged or when the oil is too thick. This allows the oil to bypass the filter through a center tube. The oil then goes straight to the engine to prevent starvation and damage.
Does a flow control valve decrease pressure?
The valve does cause the dissipation, and that leads to the reduction in pressure, but there is only flow through the valve when there is a pressure difference imposed externally across the valve. Maybe that's just semantics. The valve sort of causes the pressure drop as long as there is a flow through it.

How to tell if oil control valve is bad?
Poor fuel economy is another telltale sign of a faulty oil control valve. The ECM and oil control valve combine to ensure that your engine is running as efficiently as possible; if either one of them goes out, the timing of your engine will be thrown off, causing your car to consume more gas than usual.
What is the ECM on a camshaft?
It’s connected to your engine control module (ECM). The ECM is actually what decides how much oil goes into the camshaft at any given time, and it directs the oil control valve to open or close accordingly.
What is oil control valve?
The oil control valve is basically what controls the flow of oil into the camshaft of the engine (especially upper portion 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 PCM/ECM will control the valve and let it know what appropriate action it must take based on the engine’s performance demands.
How to tell if oil control valve is bad?
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.
What is an Oil Control Valve?
The camshafts are adjusted by oil flowing through the VVT solenoid or oil control valve.
Why does my oil control valve go bad?
Because it’s so thick, it can no longer flow through the valve and literally clogs it up to cause the failure. This is yet another reason why regular oil changes are so important. In addition, if the engine oil level gets too low , this too can cause the oil control valve to go bad.
What happens if a VVT solenoid stops working?
If the VVT solenoid stops working, the whole system may be compromised, in which may result in intake and exhaust valves opening and closing at the wrong time. This in turn can cause a drastic reduction in how many miles you can travel per gallon of fuel.
Why does my VVT solenoid go bad?
Oil is almost always the main cause of a VVT solenoid going bad. Most often, old oil is the culprit. As oil goes through an engine, over time, the combination of heat and small impurities cause the oil to thicken. If it goes on long enough before an oil change, the consistency of the engine oil is comparable to sludge.
How does a camshaft work?
Camshaft s control the timing of the intake and exhaust valves. On a dual overhead engine, there is typically one intake camshaft and one exhaust camshaft per cylinder bank. These camshafts are timed to the crankshaft via a timing belt or timing chain.
Can you use oil additives after changing oil?
There are some quality oil additives you may be able to use to clear up the clogged oil channels a bit. Only do this after you’ve changed the oil, though; additives won’t help much if your oil hasn’t been changed in 20,000 miles.
