Check the UIM. There are 2 coolant passages that go up to the throttle body, and the EGR goes between them. This area cracks and leaks. There are two ways to fix this. Replace the UIM, or block off the coolant passages. I tap the ports in the LIM and put 1/4" pipe plug in. Make those flush. I found if you pull the rubber from the gasket for those passages, fill with red RTV, and put 2 nickels there. It will seal real good. Put the UIM in place, snug it up. Wait about a hour, then torque down.
