Yep, make sure the gasket is new and that the gasket surfaces are clean, there is a change the EGR itself is leaking here are images below to help, also to clean the EGR passages use carb cleaner, and a coat hanger seems to work pretty good. The EGR valve is designed to lower peak combustion temperatures and reduce oxides of nitrogen emissions (NOx) by recirculating exhaust gas through the intake manifold and into the combustion chambers.
Check out the images (below). Please let us know what happens.
