BWD is proud to introduce a line of variable valve timing solenoids and sprockets. Scroll down to learn more about our newest product category.
Variable Valve Timing systems are designed to reduce emissions and maximize engine performance and fuel economy. The electro-mechanical system depends on the circulation of engine oil. Lack of oil circulation can cause the components to fail prematurely.
Providing a premium quality replacement for this high-tech, high-failure category, BWD is proud to introduce a line of variable valve timing solenoids and sprockets. With more than 260 SKUs in the line, BWD provides comprehensive coverage for the aftermarket.

VVT solenoids can fail due to low engine oil levels and/or irregularly changed engine oil or filters.
For a high-quality replacement, BWD® VVT solenoids feature hard anodized components to ensure proper performance and long service life.
VVT sprockets (a.k.a. cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency.
To ensure proper performance for this important category, BWD® VVT sprockets (a.k.a. cam phasers) meet tight dimensional tolerances to improve internal sealing, minimize oil drain back, and reduce frequency of PCM correction.
In addition to providing comprehensive coverage, BWD is committed to supplying professional technicians with the premium quality that’s critical for this high-tech category. That’s why BWD® VVT solenoids and sprockets undergo an in-depth design process. Our continued commitment to high-quality design and testing standards ensures that each BWD® component will endure real-world conditions.
Every variable valve timing system is slightly different, but there are three general rules to follow to ensure proper performance. First, regularly service the engine oil and filter. Second, use the manufacturer’s required engine oil type. Lastly, service the engine oil and filter after you install new solenoids or sprockets.
A few specific applications that are known to have high failure rates for solenoids include the GM 2.4L and Toyota 3.0L and 3.3L. As you can see below, BWD has these applications covered.
Will a malfunctioning solenoid or sprocket affect the vehicle operation and/or cause MIL light to stay on?
Yes. They both can affect the vehicle operating condition and cause the MIL light to come on. They both can cause multiple codes to set.
What are common causes of VVT failure?
Signs of malfunctioning VVT solenoids and sprockets:
Replacing the VVT sprocket (a.k.a. cam phaser) on a Ford 5.4L engine is an in-depth job. To help you replace it correctly, here are a few repair tips from our Installation Spotlight video.
Remove the entire camshaft. Otherwise, it will be difficult to align the sprocket’s dowel pin. If the pin isn’t aligned perfectly, it will be sheared off, causing damage to the camshaft.
Tighten the sprocket bolt to 40Nm, then tighten an additional 90 degrees.
Torque the camshaft caps to 10Nm, working your way from the center to the outside
If you’re replacing the sprocket, our master technicians recommend replacing the solenoid, too. Here are a few repair tips to keep in mind during the replacement:
Tighten the solenoid hold-down bolt to 5Nm.
"On some systems, the intake camshaft is advanced at part throttle and WOT. The placement opens the intake valve sooner and allows some exhaust gas into the intake stroke, which has an EGR effect."
