It didn’t seem like a supply line, to me, due to the dribble of oil leaking? It’s literally a drop every one or two seconds.
It’s def up on the block. Hence my initial thought of some type of sensor. (Temp/oil pressure) in fact it looks like one but the line to it threw me off.
Also the last two pics were rotated 90 degrees so it’s kind of confusing.
