Hello, my name is***** of the time the oil leaks on this engine come from the valve covers and work their way down to the oil pan. I have also seen oil seep from the head gaskets in some cases. If you cannot tell for you you need to add dye to the engine oil and then use a black light and the origin of the leak can easily be found. Oil leaks on this engine will also be amplified by any issues with the PCV system. I hope this helps. If you need anything else please let me know.
If it is a large leak it is typically the oil pump seal. When this goes bad a larger amount of oil will leak. If the oil spans from the front of the engine to the rear then it is probably the pump but if it is more confined to the rear then it is the rear main. This is assuming as you say that the oil is not seen anywhere above the pan.
You can pull the cover off of the fly wheel between the transmission and the engine. If the flywheel and torque converter are dry then it is not the rear main. If it is then the rear main is the problem.
You will just have to be sure just to check it more often before it becomes way to much to narrow down. Once you check the flywheel it will help you isolate it more.
Let me know and we can go from there. Have a great night.
