why does my Toyota Highlander smell like burning oil

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is on a level surface and the engine is cool.
• Disconnect the battery before starting work on electrical components.

2. Address Oil Leaks

• Inspect and Remove Components:
  • Remove any engine covers or components obstructing access to the leaking area.
  • Use a socket set to remove bolts.
• Replace Gasket or Seal:
  • If the valve cover gasket is leaking, remove the old gasket and clean the mating surfaces.
  • Install a new gasket, ensuring proper alignment.

3. Change Oil and Filter

• Drain Old Oil:
  • Place a drain pan under the oil pan and remove the drain plug using a socket wrench. Allow the oil to fully drain.
• Replace Oil Filter:
  • Remove the old oil filter using an oil filter wrench. Apply a thin layer of new oil to the rubber gasket of the new filter. Install the new filter hand-tight.
• Refill Engine Oil:
  • Replace the drain plug and tighten to manufacturer specifications. Use the correct type and quantity of oil as specified in the owner's manual.

4. Final Checks

• Test Run:
  • Reconnect the battery and start the engine. Allow it to reach operating temperature and check for leaks.
• Monitor oil level after the test run and top off if necessary.
