Solution

1. Preparation

Tools Required: Engine oil, oil filter wrench, socket set, clean rags, oil catch pan, torque wrench.
Disconnect the battery to prevent electrical shorts.
Allow the engine to cool completely before starting work.

2. Identify and Repair Leaks

Sub-steps:
1. Clean the engine area with a degreaser to remove old oil residue.
2. Visually inspect for leaks starting from the top of the engine and working downwards.
3. Replace any faulty gaskets, seals, or the oil filter that show signs of damage or wear.
4. Tighten the oil drain plug to the specified torque (typically 25-30 ft-lbs).

3. Replace Engine Oil and Filter

Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug and allow the old oil to drain completely.
3. Replace the oil filter using an oil filter wrench, ensuring the rubber gasket is removed with the old filter.
4. Install the new oil filter and tighten it according to the manufacturer’s specifications.
5. Reinstall the drain plug and pour in the recommended oil type (typically 0W-20 or 5W-30, depending on the engine).

4. Final Inspection

Sub-steps:
1. Start the engine and let it idle for a few minutes.
2. Check under the vehicle for any new oil leaks.
3. Monitor the oil pressure gauge and ensure it operates within normal ranges.
