So, What Causes Engine Oil Leaks
Common Place To Check Include:
The Oil Filter
Oil filters wear out; can be aligned improperly or be loose. Some vehicle models have additional parts in the filtration system; at the filter, that can leak. The filter should be changed; every time you change the oil and; should be checked for proper fitting.

The Valve Cover And Oil Pan Gasket
The valve cover gasket is probably the most common place to leak; especially in older vehicles or vehicles that are used frequently; and have a high number of miles. Over time, and with a buildup of sludge; the pressure increases which can cause leaks; and failures in the seal of the gaskets.
Sometimes damage to the oil pan on the underside; can cause minor to severe leaks. This occurs when running over road debris; large rocks if traveling off-road; and even accidentally; hitting an animal while traveling. Any of these can dent the oil pan; and compromise the seal or oil drain plug.
