Hi - this is my first project car so i'm a total newbie to mechanics. We've swapped the alternator and are currently in the process of putting the car back together but cannot figure out what is supposed to be connected to this copper/bronze looking pipe that is next to the radiator *****. Whenever the engine is started it starts squirting an oily looking substance out of it
