Summary
Some Ford and Lincoln vehicles equipped with a 2.7L or 3.0L EcoBoost engine may exhibit an oil leak from the engine oil pan RTV seal. Replace the oil pan following the procedure in Workshop Manual (WSM) Section, 303-01. After removing the oil pan it is suggested to allow the crankcase to drain overnight to minimize the chance of residual oil contaminating the crankcase sealing rail. Remove all traces of old RTV and clean the engine sealing surface using only Motorcraft├╣ Metal Brake Parts Cleaner, then wipe with Motorcraft├╣ Metal Surface Prep Wipes and allow to air dry. Refer to WSM, Section 303-00 > RTV Sealing Surface Cleaning and Preparation. If possible, allow the new RTV sealant to cure for 4 hours before refilling the engine with oil. Skipping or improperly completing steps may result in repeat oil pan leaks.
