Noticed this whilst changing the oil today - what is it and are these two pipes meant to connect to anything?

Thanks!





Pretty sure my oil leak is the sump as well - not sure if that's easier or harder than timing chain gasket though!

that is from the smog pump. My car also has the open port with nothing attatched, i believe it's a vent or dump valve, and is the source of my cold start motorboat sound. In my case, either the valve is frozen or i have a bad vacuum line to the valve, such that when the car is started cold, air from the smog pump is just exiting thru the above pictured port, rather than getting pumped into the exhaust.
