Some 2018-2020 Ford F-150 Raptor trucks and 2019-2020 F-150 Limited Series trucks equipped with a 3.5L EcoBoost high-output engine and built on or before Sept. 11, 2020, may exhibit excessive oil consumption with no visible oil leaks, with or without DTC P0365 and/or P0369.
The fix involves reprogramming the PCM and if necessary, replacing the valve covers with P/N HL3Z-6582-E (left) and HL3Z-6582-C (right).
Make sure that the vehicle is positioned on a level surface or an incorrect oil level reading will occur. When checking engine oil level, it is critical to allow a full 15-minute drain back period. Reprogram the PCM using the latest software available at www.motorcraft.com.
If the vehicle was built on or after April 1, 2019, and if both valve covers have previously been replaced, and if the vehicle has more than 4000 miles, reprogram the PCM, and replace the engine oil and filter. If the afore-mentioned criteria have not been met, replace both valve covers along with an oil and filter change.
