It’s a New Year. Time to beef up your knowledge and shop chops. In this three-part technical video series about Variable Valve Timing Systems, our own Cody Smith joins Andrew Markel and Tomorrow’s Tech University to talk about how the system works. They discuss all the good stuff, like camshaft phasers, the oil control valve (solenoid), and the variations of systems you’re likely to see out there.

In module number two, learn what can go wrong with variable valve timing systems. How the right oil is important. And what happens when the timing of the engine isn’t quite right.

In the final module of this series, learn how to diagnose and repair variable valve timings to service a vehicle and return it to like-new condition.
