Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Address Oil Leaks

Inspect Oil Drain Plug:
- Use a socket set to check if the oil drain plug is tight. If loose, tighten it to the manufacturer’s specified torque (typically 20-25 lb-ft).
Replace Gaskets and Seals:
- If any gaskets or seals are found to be leaking, remove the affected component (such as the valve cover).
  - Tools: Socket set, gasket scraper.
  - Clean the mating surfaces, apply new gasket material or replace seals as required, and reassemble.

3. Replace Oil Filter

Remove Old Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
Install New Oil Filter:
- Apply a small amount of oil to the rubber O-ring on the new filter. Install the new filter, tightening it by hand until snug.

4. Change Engine Oil

Drain Old Oil:
- Use a wrench to loosen the oil drain plug and allow oil to drain completely into a container.
Add New Oil:
- Replace the drain plug and tighten it. Fill the engine with the correct type and amount of oil as specified in the owner’s manual (typically 0W-20 synthetic oil).

5. Recheck Components

Check all hoses and connections for tightness and signs of wear. Replace any damaged components.
