I have just rooted out all of my engine leaks. The first one was coming from where I thought was my oil pan gasket. Once I replaced that it still leaked and at that point noticed it was actually coming out of my front crank shaft seal.

You might also want to check to make sure the vacuum pump seal is still good.
If it leaks out of the bottom it is impossible to see and drips off the engine looking like a leaky oil pan.
