A 2011 Subaru Forester oil leak could be caused by one of the valves or seals being worn out. Leaks can also occur due to simple errors such as not tightening the oil cap sufficiently or tightening the oil pan gasket tightly after an oil change. These oil seals can leak with age and mileage, especially the earlier black colored seals. These gaskets seal the valve covers against the mating surface cylinder head. They can shrink or crack with age and then result in an oil leak. The oil in this area is not under pressure as it is on its way to draining back to the oil pan.
