Summary

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.

Owners of these vehicles have filed 200 complaints in the engine category.
