so I have three PVC vent pipes that run though the attic. I know they go to the 3 bathrooms (99% sure) one bath (1/2 bath) on the bottom floor has a vent/fan, but the two on the 2nd floor (full baths) have no vents/fans that I know of, but I’m pretty sure those PVC pipes goes to the bathrooms. where do they end? are they just sitting above the light, or are they connected to some other weird source?
yep I change my oil every 3000
miles or when I get bored…
which ever comes first

You talking about pipes 3-4 inches in diameter? These are the plumbing vents.
I'm not sure the diameter, i'll check later. what do those do

If they exit through the roof, they are venting the sewer gas from your plumbing drain lines. The drain lines need air pressure from the atmosphere to help then flow properly.
