The best way to narrow down on the exact location of the leak is to start inspecting the underbelly of your car from the back. In places where oil doesn’t flow naturally, but is flowing due to a leak, there will be a residue of dust and sludge settled over it. Fresh oil coming out regularly is the biggest indication of an oil leak. Gradually move ahead examining the places where you can spot fresh oil. Again, due to the oil flowing from top to bottom, chances are that several places will have deposits of fresh oil.
