What happens when a cam phaser fails?
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.

What does a broken camshaft sound like?
Loud Ticking or Tapping Sounds If you're wondering what a bad camshaft sounds like, it usually makes loud ticking or tapping noises. As it starts to fail, you may notice odd sounds coming from your vehicle's valvetrain. Ticking noises are often linked to worn cam lobes.
What is a cam phaser rattle?
The startup cam phaser rattle is due to the edge of the hole the locking pin sits in wearing down. The entire purpose of this pin is to lock the VCT gears in position so you don't get the startup rattle. Once the oil makes it up the gallery and into the VCT, it slams it into the cold idle position and the noise stops.
What causes 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 does a cam phaser actuator do?
Most modern variable valve-timing (VVT) systems use a cam phaser that rotates the position of each camshaft relative to the timing chain.

Why do Ford cam phasers fail?
What Causes Cam Phasers for 5.4 Ford Failed? Low oil pressure can't deliver proper power to the cam phaser at precise timing. It could be failure oil pump or dirty oil may lead to this problem. Clear oil makes sure the viscosity for the oil to generate proper oil pressure.
Is it worth replacing a camshaft?
Due to the manufacturing processes, repairing a camshaft is not often advisable. While some high-performance engines use camshafts that are repairable, it's not really cost effective or practical for the average car on the road. Instead, if your car needs a new camshaft, replacing it with a new one is the best choice.

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.
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 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.

What happens if cam phasers go bad?
If your cam phasers are faulty, the Variable Control Timing (VCT) solenoids are likely to go bad. Moreover, the Engine Control Unit (ECU) will not be capable of controlling the phasers any longer. As a result, the timing of the engine would be hampered leading to high phaser noise.
What does a broken cam phaser do?

Why does my car make a phaser noise?
The excess phaser noise can also be caused due to a lubrication problem. If you don’t cater to it, this can cause more severe problems like valve timing issues leading to engine damage. In most cases, the ECU of the car will do all it can to protect your engine. It will enter the safe or limp mode that prevents the car engine from exceeding a specific RPM. This reduces engine power and the reduced RPM saves you from potential damage. Other than that, it also throws a code along with illuminating the car’s check engine light.

Why does my cam phaser make a noise?
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.
