2004 Silverado 5.3l 4x4
What are these plugs/vents supposed to go to? I have a few intakes and none of them are the same. The above pictured intake has a PCV vent on the top and a plug on the side. A different intake has the same PC on top plus another vent in the spot where a plug is on the one above. So where is the extra vent supposed to go to? Can I just plug it and rock and roll? It’s not the intake that came on the truck, but the one I have to use for now. The second picture is the intake I plan on using with the unknown vent in question.
