Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Ensure the vehicle is on a level surface and the engine is cool.
  • Disconnect the negative battery terminal for safety.
2. Identify and Repair Oil Leaks
  • Inspect and Clean:
    • Use a degreaser to clean the engine area where oil is present.
    • Inspect the valve cover gasket, oil pan gasket, and oil filter for leaks.
  • Replace Gaskets/Seals:
    • If leaking gaskets or seals are found, remove the affected component (e.g., valve cover).
    • Clean the mating surfaces thoroughly.
    • Install a new gasket or seal, applying the correct torque specifications.
3. Replace Cabin Air Filter
  • Access the Air Filter:
    • Locate the cabin air filter housing (usually behind the glove box).
    • Remove any screws or clips holding the cover in place.
  • Install New Filter:
    • Remove the old filter and check for oil contamination.
    • Insert a new cabin air filter, ensuring it is oriented correctly.
4. Inspect and Replace PCV Valve (if necessary)
  • Locate the PCV Valve:
    • Find the PCV valve (usually located on or near the valve cover).
  • Test and Replace:
    • Remove the PCV valve and shake it; if it rattles, it's functioning; if not, replace it.
    • Install the new PCV valve securely.
