Separator & Cap for Dodge Ram 2019-2024 2500 6.7L L6

This oil separator and cap assembly is a direct replacement for the crankcase ventilation system on Dodge Ram 2500 trucks with the 6.7L L6 Cummins diesel engine, model years 2019-2024. The separator extracts oil from the blow-by gases while the cap seals the valve cover opening.
