TSB 20-2132

This article supersedes TSB 19-2232 to update the vehicles affected. Some 2017-2019 F-150 and 2018-2019 Expedition 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.
