Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down to avoid burns.

2. Identify and Repair Oil Leaks

Locate the Leak:
- Use a flashlight to identify the source of the oil leak based on the previously conducted inspection.
Clean the Area:
- Wipe the area around the leak with a clean cloth to remove excess oil.
Replace Damaged Components:
- If the leak is from a gasket (e.g., valve cover or oil pan), remove the old gasket and replace it with a new one.
- If the oil filter is leaking, ensure it is properly tightened or replace it if damaged.

3. Replace Engine Oil and Filter

Drain Old Oil:
- Place a drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow the oil to fully drain.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Apply a thin layer of new oil to the rubber gasket of the new filter and install it.
Add New Oil:
- Reinstall the drain plug and tighten to the manufacturer's torque specification.
- Fill the engine with the recommended type and amount of oil through the oil filler cap.

4. Final Checks

Inspect for Leaks:
- Start the engine and let it run for a few minutes while checking for any new leaks.
Check Oil Level:
- Turn off the engine, wait a few minutes, and recheck the oil level using the dipstick. Add oil if necessary.
