What causes cam phasers to go bad?
Cam phasers are an essential component of modern variable valve timing (VVT) systems, helping to optimize engine performance and efficiency. However, like any mechanical part, cam phasers can fail over time. In this article, we’ll explore the common causes of cam phaser failure and provide insights into how to prevent these issues.
Understanding the Role of Cam Phasers
Cam phasers are responsible for adjusting the timing of the camshaft in relation to the crankshaft. This adjustment allows for better fuel efficiency, improved power output, and reduced emissions. They are typically controlled by oil pressure and an electronic solenoid, making them a critical part of the engine's operation.
Common Causes of Cam Phaser Failure
Several factors can contribute to cam phasers going bad. Below are the most common causes:
- Oil Quality and Maintenance: Poor oil quality or infrequent oil changes can lead to sludge buildup, which clogs the tiny oil passages in the cam phasers. This prevents them from functioning properly.
- Low Oil Pressure: Cam phasers rely on adequate oil pressure to operate. If the oil pump is failing or the engine is running low on oil, the phasers may not receive the pressure they need to adjust timing effectively.
- Wear and Tear: Over time, the mechanical components of the cam phasers can wear out due to constant use, especially in high-mileage vehicles.
- Faulty Solenoids: The solenoids that control the cam phasers can fail, either due to electrical issues or contamination from dirty oil.
- Engine Overheating: Excessive heat can damage the internal components of the cam phasers, leading to premature failure.
Signs of a Failing Cam Phaser
Recognizing the symptoms of a failing cam phaser can help you address the issue before it leads to more significant engine problems. Look out for the following signs:
- Rattling or knocking noises coming from the engine, especially at idle.
- Decreased engine performance or sluggish acceleration.
- Check Engine Light illuminated on the dashboard.
- Poor fuel economy.
- Rough idling or stalling.
How to Prevent Cam Phaser Failure
While cam phasers can fail due to normal wear and tear, proper maintenance can significantly extend their lifespan. Here are some tips to prevent cam phaser issues:
- Use high-quality engine oil and change it at the intervals recommended by your vehicle’s manufacturer.
- Ensure the oil filter is replaced regularly to prevent contaminants from entering the engine.
- Monitor oil levels and top off as needed to maintain proper oil pressure.
- Address any engine overheating issues promptly to avoid heat-related damage.
- Have your vehicle inspected by a professional mechanic if you notice any symptoms of cam phaser failure.
Conclusion
Cam phasers play a vital role in the performance and efficiency of your engine, but they are susceptible to failure if not properly maintained. By understanding the common causes of cam phaser issues and taking proactive steps to care for your vehicle, you can avoid costly repairs and keep your engine running smoothly. If you suspect a problem with your cam phasers, don’t hesitate to bring your vehicle to a trusted auto repair shop like Kevin’s Autos for a thorough inspection and repair.
Frequently Asked Questions
Will Ford help pay for cam phaser replacement?
Since the cam phaser is part of the powertrain, Ford and Lincoln Protect Extended Service Plans cover repairs associated with cam phaser failures. If you do not currently have a plan on your vehicle, it may be time to look into the benefits and features of PremiumCARE, ExtraCARE, BaseCARE and PowertrainCARE ESP Plans.
Can you delete cam phasers?
If the guides are not broken we can lock the timing chain tensioner in place and remove the camshaft-phasers. Then install an aluminum block inside the factory phaser to lock it in its correct position. We would then reassemble the engine and program your computer to not use the variable valve timing.
Does Ford have a recall on 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 terms and conditions. Owner Letters were mailed the week of September 27, 2021.

Maintenance Tips to Prevent Future Issues
Clean oil is crucial for maintaining the hydraulic operation of the phasers. Monitor Oil Pressure — Keep an eye on your engine's oil pressure. Low oil pressure can lead to inadequate lubrication and cause cam phaser malfunctions. Address any oil pressure issues promptly.
What causes a cam phaser to fail?
Oil Contamination: Dirty or contaminated engine oil can cause the cam phaser to malfunction, as the oil is responsible for lubricating and cooling the component.
What year Fords have cam phaser problems?
Ford Cam Phaser problems consisting of rattling noises and causing engine damage, or even engine failure are affecting the 2017-2020 Ford 150, and 2018-2020 Expedition. When a cam phaser fails, your Ford vehicle's VCT (Variable Control Timing) and ECU (Engine Control Unit) can be damaged.
Is there a recall on Ford cam phasers?
Owner Letters were mailed the week of September 27, 2021. Dealers should repair any affected vehicles that experience undesirable cam phaser noise after field service action 21B10, whether or not the customer has received a letter.
Can a cam phaser be fixed?
Replacing phasers will sometimes cure the problem but often rattle comes back within a few months. 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.
How to quiet cam phaser rattle?
Use of Oil Treatment (OT) for Ford Cam Phasers
All the engines showed less noise after adding the OT. When the dealership had a customer ask if there was some way to get rid of the cam phaser knock other than repair, the head of the maintenance shop at the dealership had him try adding PlanetSafe OT to his engine.
How much does it cost to repair a cam phaser?
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.
