Summary

Some 2017-2018 F-150 vehicles built on or before 10-Jul-2018 and equipped with a 3.5L EcoBoost engine may exhibit a ticking/tapping or rattle type noise from the top front cover area of the engine on initial start-up after a cold soak of 6 hours or more that may last for 2-5 seconds. This may be due to a worn variable cam timing (VCT) unit. To correct the condition, follow the Service Procedure steps to replace the VCT units and update the powertrain control module (PCM) calibration with revised VCT parameters.
