2017-2019 F-Super Duty
2016-2019 F-650/F-750
Issue: Some 2017-2019 F-Super Duty chassis cab/dual rear wheel (DRW) pickup vehicles and 20162019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an oil consumption concern in
applications where the engine is idled for extended periods of time. This may be due to high crankcase
pressure as a result of the crankcase ventilation filter element becoming restricted. To resolve the
concern, replace the crankcase vent oil separator. The new crankcase vent oil separator appears different
from the old crankcase vent oil separator as it no longer includes a serviceable filter element.
Action: Follow the service procedure steps to correct the condition on vehicles that meet all of the
following criteria:
• 6.7L diesel engine
• One of the following vehicles:
- 2016-2019 F-650/F-750
- 2017-2019 F-Super Duty chassis cab
- 2017-2019 F-Super Duty DRW pickup
