Solution

1. Preparation

Gather tools and parts needed for the job.
Ensure the engine is cool to prevent burns.
Disconnect the negative battery terminal to avoid electrical issues.

2. Identify and Fix Oil Leaks

Inspect Gaskets and Seals
- Locate the valve cover gasket, oil filter, and oil pan.
- Check for tears or wear on the gaskets.
- If damaged, replace the gaskets with new ones.
Tighten Components
- Check the oil filter and oil pan bolts; tighten if loose.
- Use a torque wrench to ensure proper torque specifications (usually 10-15 ft-lbs for oil pan bolts).

3. Replace Oil and Filter

Drain Old Oil
- Place a drain pan beneath the oil pan.
- Remove the oil drain plug with a socket set and let the oil drain completely.
Replace Oil Filter
- Use an oil filter wrench to remove the old oil filter.
- Apply a small amount of new oil to the rubber gasket on the new filter before installation.
- Install the new oil filter hand-tight.
Add New Oil
- Replace the drain plug and torque to the manufacturer's specifications.
- Add the appropriate type and amount of new engine oil (usually 5W-20 or 0W-20 for Honda Accord).

4. Final Inspection

Check for Leaks
- Start the engine and allow it to run for a few minutes.
- Inspect for any new leaks around the oil filter and oil pan.
Monitor Oil Level
- After the engine has run, turn it off and let it sit for a few minutes.
- Check the oil level on the dipstick and top off if necessary.
