I thought my pan gasket was leaking too, but after further investigation I found my leak to be the oil pressure sensor. The oil has dripped down and leaked all over the pan making it look like the pan. and like firespirit said it could be that rubber thing. So just make sure it's the pan gasket and not something stupid and easy to fix. I have yet to fix my pressure sensor but only because I leak about a 1/2 quart between oil changes.
