Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is cool.
• Disconnect the negative terminal of the battery.

2. Inspect and Replace Oil Filter

• Sub-steps:
  1. Locate the oil filter under the engine.
  2. Using an oil filter wrench, remove the old oil filter.
  3. Apply a small amount of new oil to the rubber gasket of the new oil filter.
  4. Install the new oil filter and tighten it by hand.
• Tools Required: Oil filter wrench, new oil filter.

3. Replace Valve Cover Gasket

• Sub-steps:
  1. Remove the engine cover (if applicable) by unscrewing any bolts or clips.
  2. Detach any components obstructing access to the valve cover (e.g., air intake duct).
  3. Unbolt the valve cover using a socket set, taking care to note the order of bolts.
  4. Remove the old gasket and clean the mating surfaces of the valve cover and engine.
  5. Place the new gasket onto the valve cover and reassemble it, torquing the bolts to the manufacturer's specifications (typically around 10 Nm).
• Tools Required: Socket set, torque wrench, scraper for cleaning surfaces, new valve cover gasket.

4. Address Any Other Leaks

• Sub-steps:
  1. Inspect any hoses and seals around the engine for wear or cracks.
  2. Replace worn hoses or seals as necessary to prevent future leaks.
