Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before beginning work.

2. Inspect for Leaks

Sub-steps:
1. Visually inspect the engine bay and undercarriage for oil leaks.
2. Clean any visible oil spills to better observe new leaks.
3. Use a UV dye and UV light (if available) to detect hidden leaks.

3. Replace Engine Oil and Filter

Sub-steps:
1. Place an oil drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench (torque to manufacturer specs upon reinstallation).
3. Allow the oil to drain completely.
4. Replace the oil filter with a new one, ensuring the O-ring is seated properly.
5. Reinstall the drain plug and torque it to specifications.
6. Add the recommended engine oil type and quantity as specified in the owner's manual.

4. Address Engine Wear

Sub-steps:
1. If compression test results show low compression, consider replacing piston rings or other internal engine components.
2. Consult with a professional for potential engine rebuild or replacement if necessary.

5. Monitor and Test

Sub-steps:
1. Start the engine and allow it to idle for a few minutes.
2. Check for any leaks and monitor oil pressure.
3. Take the vehicle for a test drive to assess performance and oil consumption.
