Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the negative battery terminal for safety.

2. Identify and Repair Oil Leak

Sub-step 1: Locate the source of the oil leak found during the diagnostic step.
Sub-step 2: If the leak is from the valve cover gasket, remove any engine covers and unbolt the valve cover using a socket set.
Sub-step 3: Remove the old gasket and clean the mating surfaces with a gasket scraper and cleaner.
Sub-step 4: Install the new gasket, ensuring it is seated properly, and reassemble the valve cover, torquing the bolts to the manufacturer’s specifications (typically around 7-9 Nm).

3. Replace Cabin Air Filter (If Contaminated)

Sub-step 1: Locate the cabin air filter, usually found behind the glove box.
Sub-step 2: Remove the glove box if necessary; then unclip and remove the old filter.
Sub-step 3: Install the new cabin air filter, ensuring it is oriented correctly for airflow direction.

4. Clean Engine Components

Sub-step 1: Use an engine cleaner to remove any oil residue from the engine bay and components.
Sub-step 2: Rinse with water carefully, avoiding electrical connections, and allow to dry completely.
