What is the name of the hose that comes out of the oil fill in a Dodge Ram 1500 V8 5.7L Hemi truck? Mine is disintegrated and leaking oil. I want to replace it, but I can't find a drawing or part number for this hose anywhere online.
That's the crankcase vent hose. It provides crankcase ventilation by relieving pressure and scavenging fumes from the crankcase then recirculating them through the air filter. A 5/8" or 3/4" (depending on the ID of the original) heater hose should do in a pinch for a replacement but an OEM product seems readily available.
