Thank you for your response! I thought I had broken something when I was removing the oil pressure sensor. This vent you mentioned has a large piece of metal dangling from it. I must have broken some kind of metal mount/bracket that is used to hold it in place.
I asked my son to turn the ignition enough for the radio to play, he didn't understand listen, and turned the car on with the oil pressure sensor not screwed in. There is oil everywhere, it made it extremely difficult to identify what the part is.
