Ditto on the leaky fuel pump. Most fuel pumps have a hole in the lower housing that lets at least most of the leak vent to the outside before it makes its way into the crankcase. That also accounts for the oily residue along the bottom of the engine. Air blowing over the fuel pump housing pushes the leak back along the oil pan.
