Dorman 916-777 Engine Variable Valve Timing (VVT) Sprocket - Exhaust
Dorman 916-777 Exhaust Cam Phaser
Dorman 916-777 is an OE FIX exhaust cam phaser for the variable valve timing system on select Ford and Lincoln 3.5L V6 EcoBoost engines. It is engineered for the exhaust side of the camshaft drive and is built to address common wear-related failures found in factory phasers on Ford F-150, Ford Expedition, and Lincoln Navigator applications.
Key Features
- OE FIX exhaust cam phaser for variable valve timing service
- Upgraded locking pin design with a deeper receiving seat for more secure engagement
- Concave oil wiper profile for improved sealing and reduced surface wear
- Designed to reduce timing phaser rattle associated with internal wear
- Aluminum construction with natural finish
- Timing chain drive, bolt-on attachment, and 51-tooth design
- Includes a special service tool for installation
Detailed Description
This Dorman 916-777 cam phaser replaces the exhaust-side timing sprocket on 2016-2025 Ford F-150, 2018-2025 Ford Expedition, and 2017-2025 Lincoln Navigator models with the 3.5L V6 EcoBoost engine. The design updates the factory straight-pin arrangement with a two-step locking pin and deeper seat for stronger phaser control during actuation. It also uses a concave oil wiper edge to improve oil sealing, support faster cam advance and retard movement, and reduce wear over time. For buyers searching for a Ford F-150 exhaust cam phaser replacement or a Lincoln Navigator VVT sprocket repair, part number 916-777 provides a direct-fit service solution. This part cross-references Standard Ignition VVT704 for the same application.
Common Problems This Part Can Address
- Rattling noise from a worn exhaust cam phaser
- Premature internal wear in the VVT sprocket
- Delayed or inconsistent cam timing response
- Oil sealing loss at the phaser wiper surface
- Check engine concerns related to cam timing performance
Installation Notes and Tips
Verify engine and position before installation: this part is for the exhaust side only. Confirm vehicle coverage for 2016-2017 Ford F-150 and 2017 Ford Expedition or Lincoln Navigator by build date, since those applications are listed with production-date notes. The included special service tool supports a more controlled installation process. Follow factory timing procedures and torque specifications during service.
Quality Assurance
Dorman engineered this OE FIX cam phaser with upgraded internal features and validated it using accelerated durability testing that simulates long-term real-world driving. The part is built as a standard replacement for select Ford and Lincoln VVT repairs and is backed by Dorman’s product engineering approach for service-life improvement over the original design.
