Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to ensure safety.

2. Identify the Leak Source

Clean the engine bay and surrounding areas with a degreaser to remove any oil residue.
Start the vehicle and let it run for a few minutes; observe the areas previously inspected for oil seepage.

3. Replace Faulty Seals or Gaskets

Tools Required: Socket set, torque wrench, gasket scraper, oil filter wrench.
If the valve cover gasket is leaking:
- Remove the valve cover by unbolting it using the socket set.
- Carefully scrape off the old gasket material from the valve cover and engine surface.
- Place a new valve cover gasket and reinstall the valve cover, torquing the bolts to the manufacturer’s specifications.
If the oil pan gasket is leaking:
- Drain the engine oil using an oil pan.
- Remove the oil pan by unbolting it from the engine block.
- Clean the mounting surfaces thoroughly and install a new oil pan gasket.
- Reinstall the oil pan and torque bolts to the specified values. Refill with new engine oil.

4. Replace Oil Filter (if necessary)

Remove the old oil filter using an oil filter wrench.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, ensuring it is snug but not overly tight.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and monitor for leaks.
Check the oil level and add oil if necessary.
