Your crankcase ventilation system goes from your driver side front cover to your intake tubing pre turbo. You well need to remove your engine cover and there is a long black rubber hose. It can come loose right at the front cover its just held on with a plastic clip that you squeeze to remove.
Forgive me because I am ignorant to this. But how important is the Crankcase ventilation system being disconnected? And could the Crankcase Ventilation System been disconnected from my local dealership by putting on a new cooling system fan on my new used 2015 Ram 1500 Laramie Longhorn crew cab 4 x 4 truck
