Solution

1. Preparation

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

2. Identify and Repair the Leak

Locate the Leak:
- Use a flashlight to inspect the engine components for any visible leaks.
- If necessary, clean the engine with degreaser to better identify the source of the leak.
Replace Faulty Components:
- Oil Filter:
  - Remove the old oil filter using an oil filter wrench.
  - Lubricate the rubber gasket on the new filter with a bit of fresh oil.
  - Install the new oil filter, tightening it according to the manufacturer’s specifications (usually hand-tight plus a quarter turn).
- Valve Cover Gasket:
  - Remove the valve cover bolts using a socket set.
  - Carefully lift the valve cover off and replace the old gasket with a new one.
  - Reinstall the valve cover and tighten the bolts to the specified torque (usually around 10-15 Nm, but check the specific manual).
- Oil Pan Gasket:
  - Drain the oil and remove the oil pan bolts.
  - Carefully remove the old gasket and clean the mating surfaces.
  - Install the new gasket and reattach the oil pan, tightening bolts to the specified torque.

3. Change the Oil

Drain the old oil completely and replace it with the correct type and amount of oil as specified in the owner’s manual (typically 5W-30 for the 2.0L engine).
Replace the oil drain plug and tighten it to the specified torque.
