I JUST had this job done (my brothers the machanic).. mine was leaking below the egr valve onto the block. i guess thats a common place for it to leak.. it took a little while but we also did the valve cover gaskets. (while your in there chech your valve cover gaskets since there right there). ALSO you will probably need to replace the plastic coolant elbows. mine we pretty much shot once they were pulled out.. i tried to do everything i could while i had it apart so i just bought a top end gasket set and am saving the head gaskets for my project engine! goodluck! (the coolant elbows are about $3.50 FYI)
