Today i noticed a coolant leak from the line off the EGR that goes to the intake manifold...advice, input?

Pretty straight forward, if the clamp is properly tightened then the hose is bad and needs replaced, or the tube that hose goes over is corroded and breaking apart (noticed you've got some good rust there).

By the way, that clamp is an aftermarket replacement (maybe even the hose), the stock clamps are the three-eared spring loaded type.

 

Thats right, that line and clamps came with my AEM intake.

You can see it in page 6 of the AEM instructions...

Oh, you said "stock", lol. Yeah, my Takeda intake has you do the same thing, it's just the coolant hose to the throttle body.
