Default Exhaust Leak

I ran SeaFoam through my vacuum line today. Shut the engine off and waited five minutes. I've done this before so I knew to expect dark smoke. When I restarted the car, the smoke was coming out from the base of the EGR pipe and not the tail pipe. The only leaking smoke was on the passenger side by the base of the EGR above the exhaust manifold. Any suggestions? I have a feeling that it has been leaking for a while but I only saw it today when the SeaFoam made the smoke dark.

Check to make sure all the fittings and the EGR valve are tight?

Maybe replace the egr gasket?

Seafoam is great at finding exhaust leaks.
