I was getting some fast food today and while at the order window, I could hear my engine making a popping sound from under the hood of my 2000 V70 XC SE.

When I got it home, I looked around for vacuum lines and found there was a Pierburg valve next to the radiator on the drivers side of the engine. It had a vacuum line going to it from under the intake manifold but only a 2" short piece of hose hanging down into the open air on its other port. I could not find any other rubber hose, filter or device to plug into that open hose.

I wonder what is supposed to be connected to the Pierburg hose that points downward? Since I don't have anything to connect to it, should I just block off the hose or keep it open?
