Blue: Cylinder head bolts
Red: Oil - the 4 on the bottom are drains back to the sump, the "d" shaped one on the right is supply to the head
Black: Coolant
Green: No idea (this is the one that's the biggest mystery to me)
Purple: I know there are head bolts there but there's also these "pipe" looking things that protrude up out of the block around those holes. Do they serve a purpose, like letting coolant or oil flow, or are they just there to align the head on the block or something like that?
