Replacement of the phasers alone is not the correct repair, all of the cam followers are to be replaced as well. If the phasers were replaced improperly then it could possibly cause engine damage, but it also would not run right once repair was completed.

How much does it cost to replace cam phasers?
How Much Does it Cost to Replace Cam Phasers? Replacing cam phasers is not cheap. You can expect to pay anywhere from $800 to $2500 to get the job done by a professional. Of course, the exact cost will depend on several factors, such as the year, make, and model of the vehicle.
How to tell if your cam phaser is bad?
Hearing the sound of a loud engine click noise might signify that your cam phaser is bad. The cam phaser noise is, as a result, low oil pressure due to wear in the cam sprocket in the cylinder heads. Cam phaser lockout kit is a perfect solution for engine click noise.
Why do you use the right oil for your cam phaser?
Using the right oil for your cam phaser is necessary for friction reduction and the engine’s efficient running because the engine runs at a very high temperature. The right oil guarantees that proper viscosity is generated for adequate oil pressure. Using the wrong oil viscosity can cause the cam phasers to respond slowly, thereby damaging it.
Where is the phaser on a camshaft located?
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. An oil control solenoid (often referred to as a VVT solenoid ), applies oil pressure to activate the phaser.
What happens if you don't replace 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.

Why do cam phasers make 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.
