Ford 4.6L/5.4L 3 Valve engine cam phasers

July 8th, 2009 · No Comments

Ford’s cam phasers are specially designed, computer-controlled cam gears that have the ability to adjust camshaft position (centerline – advance or retard) while the engine is running. They are used on all 2005 and newer, Ford 3 Valve Modular engines. Since the Modular 3V engine uses two camshafts, one phaser is required for each camshaft – two cam phasers per engine.
