Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool completely before starting work.
Disconnect the battery to prevent electrical shorts.

2. Identify and Repair Leaks

Inspect Gaskets and Seals:
- Check the valve cover gasket and oil pan gasket for leaks.
- If any gaskets are damaged, replace them.
Tighten Loose Components:
- Ensure the oil drain plug and oil filter are securely tightened.
Replace Damaged Oil Filter:
- If the oil filter shows signs of damage or leakage, remove it with an oil filter wrench and replace it with a new one.

3. Change Engine Oil

Drain Old Oil:
- Place an oil catch pan under the oil pan.
- Remove the drain plug using a socket set and allow the old oil to drain completely.
Install New Oil:
- Replace the drain plug with a new washer and torque it to manufacturer specifications (typically around 25-30 Nm).
- Fill the engine with the recommended type and amount of new oil (check owner's manual for specifications).

4. Clean Residual Oil

Use degreaser or engine cleaner to clean any residual oil from the engine components to prevent burning smells.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and let it idle to check for any leaks.
Monitor for burning oil smell and any unusual noises.
