Failure Symptoms

The initial symptom of a failing oil jet tube is often a localized increase in engine temperature or unusual noises from the affected area due to inadequate lubrication. If ignored, the lack of oil delivery can lead to increased friction and wear on engine components, potentially causing damage. Prolonged operation without proper lubrication can result in severe internal engine damage.

Installation Tip

Ensure the engine block's oil gallery passage is clean and free of obstructions before inserting the new oil jet tube. Be careful not to bend or deform the tube during installation, as this can alter the oil spray pattern.

Service Note

Inspect the oil pump and oil filter for any signs of blockage or wear when replacing an oil jet tube.
