Quite possibly the front main seal located behind the harmonic balancer. If that isn't it then maybe oil cooler line. Easy way to look for it is to remove the cooling fan from the water pump and put some oil safe leak detector dye in the crankcase. Also are you certain its engine oil and not possibly power steering fluid? The kit will come with a U.V. dye a pair of funny yellow glasses and a U.V. flash light. The reason I say to remove the fan is because of the wind it creates while running could blow the dye everywhere making it almost impossible to find the source.
