Common Issues This Part Addresses

• Rough or unstable idle caused by worn VVT sprocket operation
• Loss of horsepower or torque from incorrect valve timing
• Reduced fuel efficiency tied to timing control problems
• Excess noise from sprocket tooth wear or lash
• Emissions concerns related to inconsistent cam timing

Installation Notes and Tips

Confirm exhaust-side fitment by year, make, and model before installation. Inspect the timing components, seals, and related hardware during service, and follow the vehicle manufacturer’s timing procedures to maintain correct cam phasing. The OE-style installation bolt is referenced by the manufacturer where applicable.
