Solution

1. Preparation

Gather tools: socket set, oil catch pan, rags, and OBD-II scanner.
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Address Oil Leaks

Identify the Leak Source:
- Use a flashlight to inspect the engine components for oil residue.
- Clean the area around suspected leaks to identify new oil seepage.
Replace Damaged Gaskets or Seals:
- If the valve cover gasket is leaking, remove the valve cover by unscrewing bolts.
- Replace the old gasket with a new one and reassemble the valve cover, tightening bolts to the manufacturer’s torque specifications.
- For oil pan gasket leaks, drain the engine oil, remove the oil pan, clean the mating surfaces, and install a new gasket before reassembling.

3. Change Engine Oil

Drain Old Oil:
- Place an oil catch pan underneath the oil pan and remove the drain plug to let the oil drain completely.
Replace Oil Filter:
- Remove the old oil filter using an oil filter wrench, lubricate the rubber gasket of the new filter with clean oil, and install the new filter.
Fill with New Oil:
- Replace the drain plug and refill the engine with the correct type and amount of oil as specified in the owner’s manual.
