Genuine VTC Actuator Spool Valve Assembly Engine Timing Camshaft Sprocket Bolt

This VTC actuator spool valve assembly (also called a VTC spool valve, cam phaser oil control valve, or variable timing control valve) is a genuine OEM engine timing component. It is part of the variable timing control system. The system adjusts camshaft timing to help the engine make power, run efficiently, and idle smoothly.

Key Features:

• Genuine OEM replacement part built to the original equipment design
• Spool valve assembly directs pressurized engine oil to the VTC actuator (camshaft phaser) to change cam timing
• Helps support smooth idle, responsive power delivery, and fuel efficiency
• Works with the camshaft sprocket and actuator as part of the engine timing system
• Each variant in this product line is a distinct OEM part number, listed individually

Replacing a worn or faulty VTC spool valve can help address symptoms such as rough idle, rattling on cold start, reduced performance, or a check engine light related to cam timing. Using a genuine part helps keep the fit and function the engine was designed for. Always follow the factory service procedure when installing, and replace any related gaskets or seals as the procedure specifies.
