Hello. The oil can leak from any number of places on this engine. The most common places that this engine leaks oil is from the valve cover gaskets, and from the rear main seal. If it is dripping while the engine is running, then it is probably the rear main. If it only leaks once you turn the vehicle off, or if it seems to smoke when the engine is running, then it is probably the valve cover gaskets. I would typically start by checking to see how much oil is on the engine. If the engine is very dirty and is covered with oil I typically start by cleaning the engine. Once the engine is clean, I would run it to search for the leak. If the leak still cannot be pinpointed, then I add dye to the oil and use the dye kit UV light and glasses to be able to find the leak. Once it is found the leak can be fixed. If it is the rear main seal, then the transmission will need to be removed to repair it.
