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. The Workshop Manual (Section 303-00 > Diagnosis and Testing > Engine > Engine Oil Leaks) provides information on the usage of fluorescent oil dye to locate the source of an oil leak. Refer to GSB Oil Leaks Weeps And Seeps for more oil leak diagnosis. Continue to monitor OASIS for updates.
