Issue: Some 2018-2019 Expedition/Navigator vehicles built on or before 8-Apr-2019 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

update the powertrain control module (PCM) calibration with revised VCT parameters.
