Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical components.

2. Identify and Fix Oil Leaks

Inspect Gaskets and Seals:
- Remove any engine covers if necessary.
- Check the valve cover gasket, oil pan gasket, and oil filter for leaks.
- Replace any damaged gaskets or seals with new ones.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket on the new oil filter with a bit of new oil and install it.
- Tighten the new filter according to the manufacturer's specifications (typically hand-tight plus 3/4 turn).

3. Change Engine Oil

Drain Old Oil:
- Place a drain pan under the oil pan.
- Remove the drain plug with a socket wrench and allow the old oil to drain completely.
- Replace the drain plug and tighten it to the manufacturer’s torque specification (usually around 25-30 Nm).
Add New Oil:
- Pour the appropriate grade of new engine oil into the engine (consult owner’s manual for specifications).
- Start the engine and let it idle for a few minutes to circulate oil.
- Check for leaks around the oil filter and drain plug.

4. Clean Up

Remove any spilled oil and clean the engine bay to eliminate odors.
Dispose of old oil and filter according to local regulations.
