why does my Toyota RAV4 have a strong oil smell inside cabin

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.
