Problem overview

Some Ford E-350 Super Duty owners report experiencing oil leaks from various areas, such as the cylinder head and high-pressure oil pump, which can lead to engine knocking. This knocking may occur due to low oil levels or poor oil circulation, resulting in inadequate lubrication of engine components. Additionally, engine knocking can be caused by factors like a malfunctioning knock sensor or an exhaust leak. To mitigate these issues, it is crucial for owners to promptly identify and repair the source of the oil leak to prevent further engine damage. Many owners find it beneficial to seek assistance from qualified mechanics or Ford specialists to ensure accurate diagnosis and proper repairs.
