Apply RTV to the pan to block joint areas only.

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

To correct the condition, replace the oil pan with a new oil pan equipped with a press in place gasket.

Remove and discard the oil pan and oil pump seal. Clean and prepare the engine sealing surface. Install the new oil pump seal using P/N FT4Z-6626-A. Apply a 0.708 in (18mm) bead of Motorcraft High Performance engine RTV silicone to the front cover-to-cylinder block joint areas on the oil pan. The new oil pan does not require the use of RTV in any other location. Install the new oil pan P/N KT4Z-6675-D.
