- Ensure the vehicle is parked on level ground.
- Drain the oil pan. Refill oil pan to the proper capacity, refer to MBE 4000 Service Manual
(6SE420), Chapter 1, “Preventive Maintenanc”.
- If a calibration check indicates that the oil level is off by more than 2 mm (0.079 in.), contact Detroit Diesel Customer Support Center at 313-592-5800.
- Verify that the correct oil level has eliminated the excessive blue smoke concern; refer to "10.1.1 Test the Engine with the Correct Oil Level" .

To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked.
- Start and run the engine.
- Run the engine at idle under no-load conditions for approximately five minutes, allowing the engine coolant to reach normal operating range, approximately 88-96°C (190-205°F).
- Visually inspect exhaust for excessive blue smoke.
- If the engine smoke emission appears normal, no further troubleshooting is required. Shut down the engine.
- If the engine exhaust smoke is excessively blue, shut down the engine. Refer to "10.2 Improper Grade of Lubricating Oil" .
