Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Identify and Repair Oil Leaks

Inspect Gaskets and Seals:
- Remove any components obstructing access to the valve cover and oil filter.
- Check the valve cover gasket for cracks or wear; replace if damaged.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new oil filter with fresh oil.
- Install the new oil filter, tightening it according to manufacturer's specifications (usually hand-tight plus a quarter turn).

3. Refill Engine Oil

Drain Old Oil (if necessary):
- Place a drain pan under the oil pan and remove the oil drain plug using a socket set.
- Allow old oil to drain completely and replace the drain plug, tightening to the manufacturer's torque specification.
Add New Oil:
- Remove the oil filler cap and add the correct type and amount of new oil (refer to owner’s manual, usually 5W-20 for Honda engines).
- Replace the oil filler cap securely.

4. Final Checks

Reinstall Components:
- Reinstall any components removed for access.
- Reconnect the battery.

5. Test the Vehicle

Start the engine and let it run for a few minutes while inspecting for leaks.
Check the oil level again after the engine has run and top off if necessary.
