Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Identify the Leak Source

Clean the affected area using a degreaser to remove oil residue.
Run the engine and observe the cleaned area for fresh oil leaks to pinpoint the source.

3. Replace Damaged Seals or Gaskets

Oil Pan Gasket Replacement:
- Remove the oil drain plug and drain the oil into a container.
- Unscrew the oil pan bolts and carefully remove the oil pan.
- Clean the mating surfaces thoroughly.
- Install a new oil pan gasket and reattach the oil pan, tightening bolts to the manufacturer's specifications (typically around 10-15 ft-lbs).
- Refill the engine with the appropriate type and amount of oil.
Valve Cover Gasket Replacement:
- Remove any components obstructing access (e.g., air intake duct).
- Unbolt the valve cover and carefully lift it off.
- Replace the old gasket with a new one, ensuring proper alignment.
- Reinstall the valve cover, tightening bolts to the manufacturer's specifications (typically around 7-10 ft-lbs).

4. Inspect and Repair Oil Lines

Check all oil lines for signs of wear or damage.
Replace any damaged oil lines with new ones, securing them properly to avoid leaks.

5. Recheck Oil Levels and Components

After repairs, refill the engine with oil to the correct level.
Reconnect the negative battery terminal.
