Some 2018-2019 Lincoln Continental, 2018 MKX and 2019 Nautilus vehicles equipped with a 2.7L or 3.0L EcoBoost engine, built on or before Aug. 1, 2019, may exhibit an engine oil pan leak RTV seal.

Remove and discard the oil pan and oil pump seal. Clean as needed and install a new oil pump seal P/N FT4Z-6626-A and oil pan KT4Z-6675-D. Apply an 18mm bead of Motorcraft High Performance Engine RTV silicone to the engine front cover-to-cylinder block joint areas on the oil pan.

Caution: Do not use the oil pan with a press-in-place gasket on 2015-2017 model year vehicles as this pan is not equipped with a PCV check valve and can result in oil consumption.
