Try tightening the pan bolts to 20 lb/ft of torque. If that does not stop the leak then you will have to remove the pan and replace the gasket. Check the bolt holes in the pan to make sure they have not been overtightened and dimpled. If so, make sure you tap them with a hammer to flatten out the surface. Go easy and just flatten them out, so the gasket will seal properly.
