What is the most common oil leak in a Subaru?

The most common oil leak in a Subaru is from the camshaft seals and the valve cover gasket [[3]]. The camshaft seals, located behind the camshaft sprockets, can leak oil with age and mileage, especially if they are the older black seals. The newer brown seals are more resilient. The valve cover gasket can also weaken over time, allowing oil to seep through. These leaks can result in droplets of oil under the vehicle, a smoky exhaust, the smell of burning engine oil, and engine noise without lubrication .
