Glenn Janes got a repair quote of $2,600 to $3,000 to repair a cam phaser knock on his 2008 Ford Expedition. The Ford service manager gave him 3oz of OT to try in his next oil change to see what happens. Cam phaser knock is no more. OT cost...$4.00 savings...$2,596.00. Watch to see how.
Cam phasers have been a significant issue in several 3 valve Ford engines. For more details on how to use PlanetSafe OT and other cam phaser knock problems and fixes please see these pages for more information.
