Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil catch pan, rags, flashlight.
Safety Warnings: Allow engine to cool before working on engine components.

2. Address Oil Leaks

Locate the Leak Source: Identify where the oil is leaking from based on the earlier inspection.
Clean the Area: Wipe down any oil residue from the engine components with rags.
Replace Gaskets or Seals:
- If the valve cover gasket is leaking, remove the valve cover by unscrewing the bolts (typically 7-10 ft-lbs torque).
- Replace the old gasket with a new one and reassemble the valve cover.
Tighten Oil Filter and Drain Plug: Ensure both are secure; replace the oil filter if necessary.

3. Change Engine Oil and Filter (if necessary)

Drain Old Oil: Place the oil catch pan under the oil pan, remove the drain plug, and allow oil to fully drain.
Replace Oil Filter: Use an oil filter wrench to remove the old filter and install a new one, applying a thin layer of oil to the rubber gasket before installing.
Add New Oil: Replace the drain plug, and fill the engine with new oil as per manufacturer specifications.
