Mercedes-Benz ML320 oil leak from oil pan with accumulation on axle on Mercedes-Benz ML320

Some Mercedes-Benz ML320 owners report experiencing oil leaks from the oil pan that accumulate on the axle. These leaks can occur if the oil pan gasket is not properly cleaned during replacement, as any residue can worsen the issue. Additionally, failing to adhere to the correct torque specifications and tightening patterns for the bolts may compromise the seal, leading to further leaks. Owners have also noted that oil leaking into the spark plug well may indicate separate issues that require attention. The oil filter housing is another potential source of leaks that should be inspected. Furthermore, some owners find that rear engine leaks can be traced back to components like the oil separator and cam plugs, which may need replacement. If the oil pan gasket fails, it can significantly contribute to oil leaks. For persistent leaks or uncertainty about their source, it is recommended that owners seek professional inspection and repair services to accurately diagnose and resolve the issue.
