Solution

1. Preparation

Tools Required: Socket set, oil catch pan, rags, OBD-II scanner.
Ensure the vehicle is on a flat surface and the engine is cool. Disconnect the battery before starting work.

2. Inspect and Repair Leaks

Identify Leak Source:
- Clean the engine area with a degreaser.
- Start the engine and visually inspect for any leaks.
Repair or Replace:
- If the leak is from a gasket, replace the gasket (e.g., valve cover gasket, oil pan gasket) as needed.
- Tighten any loose bolts or replace damaged components (e.g., oil filter, oil drain plug).

3. Change Engine Oil

Drain Old Oil:
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug and allow the old oil to fully drain.
Replace Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Lubricate the rubber gasket of the new oil filter with a bit of new oil and install it.
Add New Oil:
- Replace the drain plug and torque it to the manufacturer's specification (usually around 20-25 ft-lbs).
- Add new oil through the oil filler cap, using the specified oil type (e.g., 5W-30).
Check Oil Level:
- Wait a few minutes, then check the dipstick and add oil if necessary.
