I just got my first Dodge Ram with a 98 Cummins 24v. I notice on the front of the block, there is a tube running down and drips oil. We have noticed a bit of oil spots on each side of the truck and in the front wheel wells. What would cause oil to come out of this tube and what is it for? Would that be the cause of the oil spotting on the side of the truck? The dealer just changed the oil, would excess oil vent out of this tube? Thanks in advance.
