In this video I share my experience and knowledge of the Ford F-150 3.5L Ecoboost cam phaser rattle upon start up. I give a great example of what the noise sounds like. I also explain what, in my understanding, causes this issue by dissecting a cam phaser and showing the failed part. In addition to this I display how the cam phaser and camshafts behave while this noise is happening by rotating the crankshaft of a 3.5L with the valve cover removed so that the valve train can be seen in motion. Finally, I share my experiences with two different repair methods made available for to rectify this issue.

This noise that usually occurs upon start up after the vehicle has been sitting, not running, for several hours. Ford F-150s equipped with the 3.5L Ecoboost from 2013- roughly present day can exhibit this noise. It can also show up in the Ford expedition and Lincoln navigator equipped with the 3.5L Ecoboost.
