Dodge Sprinter 2500 engine oil leak primarily from the driver side, possible cooler leak on Dodge Sprinter 2500

Some Dodge Sprinter 2500 owners report experiencing engine oil leaks primarily on the driver side, which may be related to oil cooler leaks. Common causes of these leaks include worn-out drain plugs, damaged gaskets, and oil system component failures. Owners of models with the OM642 V6 engine are particularly prone to oil cooler seal leaks, which Mercedes has addressed by updating the seals to a more durable Viton material. However, the oil cooler is located in a difficult-to-reach area, making repairs labor-intensive and potentially costly. The oil cooler's placement in the valley between the cylinder heads, along with the need to drain coolant and oil during repairs, adds to the complexity. It is recommended that owners suspecting an oil cooler leak consult a qualified mechanic for diagnosis and timely resolution to prevent further engine damage.
