Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues during the repair.

2. Identify the Leak Source

Sub-steps:
- Clean the engine area using a degreaser to remove old oil residues.
- Start the engine and allow it to idle while observing for fresh oil leaks.
- Use a flashlight to inspect suspected areas once the oil is clean.

3. Replace Damaged Seals or Gaskets

Sub-steps:
- If the valve cover gasket is leaking:
  1. Remove any components obstructing access to the valve cover.
  2. Unscrew the valve cover bolts and carefully lift off the cover.
  3. Remove the old gasket and clean the mating surfaces.
  4. Install a new gasket and reassemble the valve cover.
- If the oil pan gasket is leaking:
  1. Drain the engine oil using a wrench to loosen the drain plug.
  2. Remove the oil pan by unbolting it, taking care to not damage the surrounding areas.
  3. Replace the old gasket and reattach the oil pan with new bolts, ensuring proper torque specifications (typically around 10-15 Nm).
  4. Refill with the appropriate engine oil (5W-30 synthetic recommended).

4. Reassemble and Test

Sub-steps:
- Reconnect any components removed during the process.
- Reconnect the battery.
- Start the engine and monitor for leaks.
- Check the oil level again and top off if necessary.
