Official summary
Some 2018-2021 F-150 vehicles equipped with the 3.0L diesel engine may experience low oil pressure at idle after an oil change. This condition may be caused by a broken anti-drain back oil plug in the oil filter adapter. The anti-drain back oil plug is now available to be serviced separately from the oil filter adapter. To correct this condition, follow this service procedure to replace the anti-drain back oil plug.
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.
