Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, OBD-II scanner, inspection mirror.
Ensure the engine is cool and disconnect the battery before beginning work.

2. Identify and Repair Oil Leaks

Inspect the Valve Cover Gasket:
- Remove the engine cover if applicable.
- Use the inspection mirror to check for oil seepage around the valve cover.
- If leaking, remove the valve cover bolts, lift the cover, replace the gasket, and reassemble.
Check the Oil Filter:
- Inspect the oil filter for tightness and any signs of leaks.
- If leaking, remove the old filter using an oil filter wrench, lubricate the rubber O-ring on the new filter with oil, and install the new filter. Torque according to specifications.

3. Clean Up

Use rags to wipe any oil spills on engine components.
Allow any spilled oil to be properly disposed of using an oil catch pan.

4. Refill Engine Oil

If oil levels were low, refill with the recommended grade of engine oil specified in the owner’s manual.
Check for leaks after refilling and running the engine for a few minutes.
