Solution

1. Preparation

Tools Required: Safety gloves, drain pan, socket set, torque wrench, OBD-II scanner, oil filter wrench.
Ensure the vehicle is on a level surface and allow the engine to cool before beginning repairs.

2. Address Oil Leaks

Identify the Source of the Leak: Based on your visual inspection, locate the area of the leak (e.g., oil filter, valve cover, or oil pan).
Replace Damaged Components:
- For the oil filter: Use an oil filter wrench to remove the old filter. Apply a small amount of clean oil to the gasket of the new filter, then install it by hand until snug.
- For gaskets: Remove the old gasket material, clean the surface thoroughly, and replace with a new gasket. Torque to manufacturer specifications.
- For the oil pan: If leaking, drain the oil and remove the oil pan bolts. Replace the gasket or sealant, reattach the pan, and torque to spec.

3. Change Oil

Drain Old Oil: Place a drain pan under the oil pan, remove the drain plug, and allow the oil to fully drain.
Replace Oil Filter: As mentioned above, remove and replace the oil filter.
Add New Oil: Replace the drain plug and refill the engine with the manufacturer-recommended oil type and quantity.

4. Test and Monitor

Start the engine and allow it to run for a few minutes. Check for leaks around the repaired area and monitor the oil level again.
