Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags for cleanup, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery for safety.

2. Oil Leak Repair

Sub-steps:
1. Drain the Engine Oil: Place an oil catch pan under the oil pan, remove the drain plug, and allow the oil to completely drain.
2. Remove and Inspect the Oil Filter: Use an oil filter wrench to remove the old oil filter. Inspect for any leaks from the filter.
3. Replace the Oil Filter: Apply a small amount of fresh oil to the rubber O-ring of the new filter. Install the new filter hand-tight.
4. Inspect and Replace Gaskets: If the valve cover or oil pan gaskets are damaged, remove the necessary components to access them. Clean the surfaces thoroughly and replace the gaskets, ensuring proper alignment.
5. Reinstall the Drain Plug: Tighten the drain plug to the manufacturer’s specified torque (typically around 20 lb-ft for many Honda vehicles).
6. Refill with Oil: Pour the appropriate type and amount of engine oil back into the engine (typically 5W-20 for Honda Pilot). Check the level with the dipstick.

3. Additional Repairs (if required)

If the issue persists after gasket replacement, inspect components such as the oil pressure switch or turbocharger (if equipped) for leaks, and replace as necessary.
