Symptoms

• Distinct smell of oil inside the cabin
• Visible oil leaks under the vehicle

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery for safety.
• Ensure the engine is cool before inspection.

2. Inspect and Clean Engine Components

• Tools Required: Socket set, shop towels
• Remove the engine cover (if applicable) to access the engine components.
• Wipe down any visible oil from the engine surfaces to help identify new leaks.

3. Replace Faulty Components

• Tools Required: Oil filter wrench, torque wrench

• If leaks are found at the oil filter or oil pan:

  1. Remove the old oil filter using the oil filter wrench.
  2. Install a new oil filter, ensuring to lubricate the rubber gasket with a little fresh oil.
  3. Tighten the filter to the manufacturer’s specifications (typically hand-tight plus 3/4 turn).

• If the oil pan gasket is leaking:

  1. Drain the oil and remove the oil pan bolts.
  2. Carefully remove the oil pan and clean the mating surfaces.
  3. Install a new gasket and reattach the oil pan, torquing the bolts to the specified value.

4. Check and Replace Cabin Air Filter

• Tools Required: Flathead screwdriver (if applicable)
• Remove the cabin air filter access panel.
• Replace the cabin air filter with a new one, ensuring it is seated correctly.

5. Reassemble and Refill
