Ford F-350 Super Duty oil leaking from replaced oil pan gasket on Ford F-350 Super Duty

Some Ford F-350 Super Duty owners report experiencing oil leaks from the upper oil pan, which is a known issue in Ford 6.7L engines due to a common seal failure. These leaks can be significant, often requiring the removal of the transmission and slight jacking of the engine for proper seal repair. Additionally, oil leaks from the upper oil pan can eventually lead to complications at the oil pan itself. Repairing these leaks is often complex, as many owners have noted the extensive involvement required based on repair videos. While not always categorized as urgent, it is crucial to address upper oil pan leaks to prevent further engine damage. If oil leaks persist after replacing the oil pan gasket, owners are advised to inspect the upper oil pan seal and consult a qualified mechanic or Ford dealership for effective diagnosis and resolution.
