Official summary
Some 2017-2019 F-150 and 2018-2019 Expedition/Navigator vehicles built on or before 1-Apr-2019 and equipped with a 3.5L EcoBoost engine may exhibit excessive oil consumption with no visible oil leaks with or without diagnostic trouble code (DTC) P0365 and/or P0369. This may be due to a concern with the positive crankcase ventilation (PCV) system. To correct the condition, follow the Service Procedure steps to verify the condition and replace the valve covers.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
