have an important hose question with *pics*
 

I just wanted to know if anyone knew where this hose, coming from the top of the block to the bottom of the upper intake manifold, is actually supposed to go? another forum member described this as being in the wrong place causing my current leakage of coolant going through the block.

So if anyone can tell me where this connection is supposed to go, I would appreciate it. since I have a bad leak and don't know what is causing it. hopefully this is wrong i guess.
