Why does my cam phaser make a knocking noise?
In a typical scenario, worn cam phasers make a loud and rough idle. Oftentimes, a knocking noise is heard. There are also instances in which the noise does not result from the wear in the phasers. Instead, it is caused by low oil pressure resulting from cam bearing wear in the cylinder heads.
Can a bad cam phaser cause a bad VCT?
Really far gone cam phasers can destroy a VCT, causing the timing of the engine to be so far gone it doesn't even idle (or start) once it gets warm and the system goes out of "warmup" mode, so watch out for changing a potentially bad VCT and not changing the associated cam phaser.

What causes cam phaser failure?
Not counting high mileage and wear over time, the primary cause of cam phaser failure is related to engine oil. Cam phasers need lubrication which is provided by motor oil. When the oil pressure is low, the cam phaser will not get enough lubrication, causing them to wear out more quickly.

What is cam Phaser noise?
The cam phasers are used to advance and retreat cam timing. This is oil pressure controlled by variable cam timing solenoids. When commanded, the solenoids direct oil pressure to advance or retreat the timing. If the pressure drops due to a malfunctioning part, it will cause a knocking noise.
What happens if you don't fix cam phasers?
A malfunctioning phaser can prevent the valve timing from advancing or retarding as needed. As a result, the engine may exhibit performance problems, such as rough running and poor acceleration.
What happens when cam phasers go out?
The common design of cam phasers is to get into a locked position when idle. However, a faulty cam phaser will fail to lock back into place at idle. The wrong positioning of the cam phaser creates a rattling or knocking sound near the top of the engine. This noise is most evident when the engine is hot and idle.

How does a valve timing system work?
How Variable Valve Timing and Phasers Work. In a traditional engine, valve timing (when the valves open and close) is fixed. But with a modern VVT system, the position of the camshaft (s) can be adjusted, thereby altering valve timing. Having this ability can improve engine performance, increase fuel economy, or both.
What is a camshaft phaser?
One or more camshaft actuators —also known as camshaft phasers—act as the heart of the VVT system. Some vehicle manufacturers refer to camshaft actuators as phasers, while others use different terminology.
What is a phaser in a VVT?
One or more camshaft actuators—also known as camshaft phasers —act as the heart of the VVT system. When conditions are correct, the phasers alter the position of the camshafts to adjust the engine’s valve timing. Although camshaft phasers sound great in theory, they’re a common failure point on many modern engines.
How do camshafts work?
Inside the engine, there’s a crankshaft and one or more camshafts. The camshafts open and close a series of valves that allow air (and fuel, in the case of port injection) into the engine and exhaust gases out. A timing chain (or timing belt) connects the crankshaft to the camshafts.
Where is the actuator located on a VVT?
Most vehicles use a hydraulically-operated phaser (aka actuator) located at the end of the camshaft to change the camshaft’s position and retard or advance valve timing.
