996-1004Dorman
DORMAN 1.42" x 1.35" x 0.25" Engine Oil Separator Repair Kit for Freightliner - Dorman 996-1004 Engine Oil Separator Compatible with Select Models - Dorman Engine Oil Separator 996-1004 - Oil Separator Repair Kit - Repair Kit - Oil Separator Repair Kit - This crankcase breather repair kit directly replaces the crankcase breather element on specific vehicles. It features the exact fit, function and performance as the factory part, and can potentially save you time and money if the OEM dealership only has the complete breather assembly, forcing you to also buy the lower aluminum housing, even if that isn't the failure point. The separator can fail on its own, either by clogging, cracking, or having a separator bearing fail from age and wear, which is indicated by noise and vibration. Excessive oil mist from the gas outlet can also be a failed separator symptom. When any of those failures occur, you can replace the separator with this kit, reducing part costs and install time by not having to replace the lower housing on the engine block. - Freightliner 2023-15, NFI 2021-19, NFI 2015, Van Hool 2021-15, Western Star 2022-15
