Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Socket set
- Oil catch pan
- Rags or paper towels
Ensure the vehicle is parked on a level surface and the engine is cool before starting the work.

2. Identify and Fix Leaks

Steps:
1. Locate the Leak: Use a flashlight to identify the source of the oil leak in the engine compartment.
2. Clean the Area: Wipe down any oily areas with rags to prevent further contamination and allow for better inspection.
3. Tighten Bolts: If the leak is from a loose component (e.g., oil filter or valve cover), tighten the bolts to the manufacturer’s specified torque.
4. Replace Gaskets/Seals: If gaskets or seals are damaged, remove the old gaskets and clean the mating surfaces. Install new gaskets/seals according to specifications.

3. Change Oil and Filter (if needed)

Steps:
1. Drain Old Oil: Place an oil catch pan under the oil pan, remove the oil drain plug, and allow old oil to fully drain.
2. Replace Oil Filter: Using an oil filter wrench, remove the old oil filter. Apply a small amount of new oil to the rubber gasket of the new filter and install it.
3. Reinstall Drain Plug: Once oil has fully drained, reinstall the drain plug and tighten it to specification.
4. Add New Oil: Fill the engine with the recommended type and amount of oil using a funnel. Check the dipstick for proper level.

4. Test Drive and Monitor

Steps:
1. Start the engine and let it idle for a few minutes while checking for leaks.
2. Take the vehicle for a short test drive to ensure there are no burning smells or leaks.
3. Monitor the engine temperature and check for any unusual noises.
