– VVTL-i Variable Valve Timing and Lift-intelligent Controls the intake and exhaust camshafts and the cam changeover mechanism to realize an optimal valve timing After the VVT gear is slid in the arrow direction as shown in Figure 7, lower the VVT gear and remove the chain from the VVT gear. This noise is the result of a VVT controller pin not engaging at start-up. Variable Valve Timing (VVT) Tech Tips: VV5000 VV1001 Variable Valve Timing (VVT) Sprockets Variable Valve Timing (VVT) Solenoids Q21002 Ford F-Series Trucks & Expedition (2013-05) Variable Valve Timing (VVT) systems are designed to reduce emissions and maximize engine performance and fuel economy. Turn the timing gear pulley clockwise until the screws at the oval holes are in the limit position. The concept of increasing low- and high-speed engine torque by automatically advancing and retarding valve timing isn’t a new thing.

Cleared the code and drove it (which is what the dealer would do anyway). If the rattle noise is coming from the upper timing cover area, the cam adjuster may not lock in place when the engine is shut off. This can cause noise and rattle at idle and startup.
