ok.. I'm still in the process of putting my engine back in.. I noticed on my egr solonoid there's the vac lines the comes from the throttle body, and on the other end of it there's the line that goes to the egr .. well also on this side there seems to be another vac line connection which I don't recall ever hooking up.. anyone know?

 

?

 

could it just be some kind of bleed off?

 

Yes, that is the "vent". Nothing goes to that. There should be a little "sponge" type filter on it though.....
