Leaking oil filter housing gasket weeps oil and it runs onto the front of the motor, collecting dirt over time. Mine looked the same - it was not the VC gasket. I replaced the oil filter housing gasket and cleaned it up with brake clean. Remove the belly pan and use a large drain pan or drip pan available from an auto parts store or even a big sheet of cardboard to catch the runoff.
