Sounds like a vacuum leak



I'm pretty sure there is a vacuum leak somewhere. There is an airy noise coming from the engine but I can't determine where it's coming from. There were some open ports on the carb that I put caps on but there is still a noise that sounds like sucking air. I have a vacuum gauge but I don't know where to hook it up. There is a port coming out of the front of the engine next to the distributor that looks like it could be the spot to hook up the vacuum gauge but there are three ports coming off of it and they're all open. I'm not sure if those are supposed to be plugged up or not. Also the pcv valve is missing. How necessary is it to have one? Thanks again for all of the help!
