Some 2017-2018 F-150 vehicles equipped with a 3.5L EcoBoost engine built at Kansas City Assembly Plant on or before 23-Feb-2018 or Dearborn Truck Plant on or before 26-Feb-2018 may exhibit an oil leak from the 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 contaminating the sealing rail. Prepare the engine sealing surface following the procedure in WSM Section, 303-00. Proper usage of the Motorcraftù Metal Surface Prep Wipes is critical. If possible, allow the new RTV sealant to cure for 4 hours before refilling the engine with oil. Correctly following the WSM procedures is critical. Skipping or improperly completing steps may result in repeat oil pan leaks.
