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.
There are two main reasons why phasers fail – wear inside the cam phasers and wear in the engine, typically it’s a combination that causes excessive phaser noise. Wear inside the phaser means the oil cannot be properly controlled and the computer cannot control the variable cam timing.
Does Ford pay for cam phaser replacement?
If an affected vehicle exhibits this condition, dealers are to replace all four cam phasers. This service will be covered by Ford Motor Company following the proration table contained within the terms and conditions.
Ford has issued multiple technical service bulletins (TSBs) related to the operation of the cam phasers on the 3.5L EcoBoost engine.

Why do cam phasers fail?
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. Any debris or sludge will influence oil flow and pressure.
Does Ford warranty cover cam phasers?
If an affected vehicle exhibits this condition, dealers are to replace all four cam phasers. This service will be covered by Ford Motor Company following the proration table contained within the term and conditions.
Does the 3.5 EcoBoost have VVT?
The first-gen 3.5-liter EcoBoost combined twin-turbocharging, direct injection, and variable valve timing. This was Ford’s first stab at combining all three.
What does a cam phaser lockout kit do?
Cam Phaser Noise Solution Kit – Locks the phasers into a fixed position and the ticking noise stops completely. Eliminate the noise and prevent it from reoccurring in the future.
How much is it to replace cam phasers raptor?
$1,200 seems to be about right.
Does 5.0 Coyote have cam phasers?
2015-2017 5.0L/5.2L COYOTE HIGH PERFORMANCE CAM PHASER
These high-performance cam phasers have a much lower leak rate than stock, allowing better control of the phasers at higher engine speeds and loads. These cam phasers are oriented for racing applications.
An aftermarket camshaft phaser typically costs around $20 and $330, depending on its material, product fit, series, color or finish, warranty, brand, and set or kit inclusions. If you want a professional mechanic to do the job for you, it may cost you an additional $800 to $2500.
What do cam phasers do with a Ford engine?
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 is a phaser rattle?
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 the phaser effect sound like?
It also sounds a bit like a wah pedal but without the heavy-handed, vocal nature inherent in that effect. The filtering is accomplished by creating a phase difference at certain frequencies and then mixing those signals with the dry signal to cause frequency-dependent phase cancellation.

How do you quiet noisy cam phasers?
You can decrease the cam phaser noise by using an oil treatment. This is a cheap stop gap fix which may buy you some time but ultimately you will have to go for the permanent repair option.
It is required to prevent piston-to-valve interference when increasing Valve Lift and Duration.
How can I make my engine rattle quieter?
How Can You Quiet Your Car Engine? Once you verify the lifter ticking is not caused by a worn-out lifter or some other damaged part, the best thing to do is change the oil. Get rid of all the oil currently in the engine and flush it out before adding new oil.
How do you reduce valve noise?
Common source treatments include noise-attenuation control valve trims, inline diffusers, and vent diffusers that minimize turbulence. Typical path treatments include increasing the pipe thickness, adding acoustical or thermal insulation, or adding inline pipe silencers.
