What happens when a cam phaser goes bad?
When a cam phaser goes bad, the Variable Control Timing (VCT) solenoids would be destroyed, and the engine control unit (ECU) would no longer be able to control the phasers. If not attended to, it can lead to valve timing problems which would eventually damage the engine.
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.
What does cam phaser do?
The phaser cavity changes the valve timing by rotating the camshaft slightly from its initial orientation, which results in the camshaft timing being advanced or retarded. The PCM adjusts the camshaft timing depending on factors such as engine load and RPM.
Can a cam phaser be fixed?
The sure fix to phaser problems is to lock the variable cam timing by essentially turning the phaser into a fixed timing gear. The WMS Cam Phaser Lockout kit will solve the phaser issue permanently.
What causes cam phaser knock?
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.
Is it worth it to replace Cam phasers?
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 do you stop cam phaser problems?
Is it worth it to replace cam phasers?

Why do Ford cam phasers fail?
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 in the engine means not enough oil can make it to the phaser, so even a new phaser cannot operate properly.
How does a cam phaser work?
A “cam phaser” is just an adjustable camshaft sprocket that can be turned by means of a computer-controled servo. Rather than just setting a certain amount of advance or retard, the computer can advance the cam or cams at low rpm to enhance driveability, and retard the cam or cams at high rpm for more horsepower.
What is the purpose of camshaft?
A camshaft is the element of an internal combustion engine the purpose of which is to open and close the valves.
What is an engine cam?
Cam engine A cam engine is a reciprocating engine where, instead of the conventional crankshaft, the pistons deliver their force to a cam that is then caused to rotate.
What does camshaft do?
The camshaft is critical to the basic function of an engine. Comprised of two distinct parts, the cams and the shaft, the camshaft is the element that enables valves to open. As the shaft rotates, the egg-shaped cams (or “lobes”) push the valves open in sync with the crankshaft gear.
