The lower and upper intake gaskets will NOT allow oil to drip, so anyone with some common sense would know that. Those will only leak while driving. The oil pan... drop it, change oil pan gasket, and retorque on the torque sequence and rating for a 3800. I don't know how mechanically inclined your mom is.. so she may want to take it to a shop. After I changed my oil pan I leaked a little oil because I didn't torque the oil pan down in the proper sequence.. so it leaked, not a lot, but enough for me to notice. I am anal, though.
