Though, That hard line/vacuum line on the inner side of the timing cover, that is circled. That leads from a soft line off the bottom side of your intake manifold, then connects to the hard line in the picture, & follows the contour of the VC, until it meets up with yet another Vacuum line "soft" that leads off to...

I forget where it goes after it meets near the Thermostat housing... Shit. It MIGHT be for the Evap Solenoid/Canister, not absolutely positive on that though. I'm talking about the one I see circled in the picture.

EDIT: Got some pictures for you, to show you what I mean.
