Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, oil catch pan, rags, multimeter.
Safety Warnings: Disconnect the battery before starting any electrical work. Allow the engine to cool before beginning the inspection.

2. Addressing Oil Leaks

Locate the Leak: Identify the source of any visible oil leaks.
Remove Affected Components: If necessary, remove engine covers or other components to access the leaking area.
Replace Gaskets or Seals: Replace any worn gaskets (such as valve cover gaskets) or seals that are causing the leak.
Reassemble Components: Reinstall any components that were removed, ensuring all bolts are torqued to manufacturer specifications.

3. Oil Change

Drain the Old Oil: Use an oil catch pan to drain the old oil from the oil pan by removing the drain plug.
Replace Oil Filter: Remove the old oil filter and install a new one, lubricating the rubber gasket on the new filter with fresh oil.
Add New Oil: Replace the drain plug and fill the engine with the appropriate type and amount of new oil as specified in the owner’s manual.
Start the Engine: Run the engine for a few minutes to circulate the new oil and check for leaks.

4. Final Inspection

Check for Leaks: After running the engine, inspect the previously leaking area to ensure no new leaks appear.
Monitor Oil Level: Keep an eye on the oil level over the next few days to ensure it remains stable.
