Welcome to the 'bolt Sarah!
Its hard to be sure from the picture, but does that line that's hanging loose go to the canister under it? If so that confirms it is associated with the oil filter.
There should be a second line from that canister too. Where does it go?
The valve cover does look like a 235 to me, but could it be a 261? I ask because of the size of that line we all seem to think is an oil line.
