Official summary
Some 2015-2019 F-Super Duty and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an oil leak from the oil filter, crankcase vent oil separator, oil cooler, upper/lower oil pan. This may be due to a clogged crankcase vent oil separator and/or a sealing concern. Do not remove/replace the engine front cover for upper oil pan leaks. Do not check for warpage on the upper oil pan. When the upper oil pan is not bolted to the vehicle, it has a natural tendency to twist slightly due to the manufacturing process for the pan and will not result in an oil leak.
