Oil pan leak

First be sure it is the pan. There are several other places for oil to leak, and migrate with the help of the fan and gravity, causing all oil to end up at the bottom rear of the pan. Some notable ones would be the valve covers, oil sender, oil filter adaptor and the fuel pump. All can possibly leak and show up at the pan.

I'd clean the begeebeez outta it with brakeclean to be sure the source..

Nothing worse than spending hours repairing the wrong thing, only to have the leak remain..
