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 issues.

2. Identify and Repair Leaks

Inspect Gaskets and Seals:
- Remove any components obstructing access to the oil pan and valve cover.
- Use a flashlight to inspect gaskets for cracks or wear.
- Replace any damaged gaskets or seals with new ones.
Tighten Loose Components:
- Use a torque wrench to tighten the oil pan and valve cover bolts to the manufacturer's specifications.

3. Replace Oil and Filter

Drain Oil:
- Place an oil catch pan under the oil pan.
- Remove the drain plug and allow old oil to completely drain.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber O-ring on the new filter with fresh oil, then install it.
Add New Oil:
- Reinstall the drain plug and torque it to specifications.
- Fill the engine with the recommended type and amount of oil.

4. Test for Smoke

Start the Engine:
- Reconnect the battery and start the engine.
- Allow the engine to idle and observe for any smoke or odors.

5. Final Inspection

Check for Leaks:
- After the engine has run for a few minutes, inspect the area around the oil filter and drain plug for leaks.
Monitor Oil Level:
- After a short drive, recheck the oil level and top off as needed.
