Service bulletin TSB 21-2192

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2017-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L may exhibit an engine oil leak. This may be due to the mating surface of the upper oil pan and the engine block. An oil leak in this area may also be influenced by a blocked crankcase oil vent separator. To correct the condition, follow the Service Procedure to reseal the engine block.

SSM 523352024-03-20. Service bulletin. For 2015-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual (WSM), Section 303-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.
TSB 22-22482024-03-07. Service bulletin. This article supersedes TSB 22-2201 to update the Service Procedure and Parts List. 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, or upper/lower oil pan. This may be due to the mating surfaces of the upper oil pan and the engine block or to a clogged crankcase vent oil separator.
SSM 516912023-06-16. Service bulletin. 2011-2023 F-Super Duty and 2016-2024 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C (80°F) and may increase to 1200 RPM at -40 °C (-40°F). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
SSM 512942023-01-31. Service bulletin. Some 2016-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L engine may require the lower intake manifold to be removed for various concerns. The WSM, Section 303-01, has been updated to remove the lower intake manifold leaving the crankcase vent oil separator attached. Both parts should be removed from the engine together to avoid discarding and replacing the crankcase vent oil separator.
