Solution

1. Preparation

Tools Required: Socket set, wrench set, oil catch pan, rags, OBD-II scanner (if applicable).
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery if working near electrical components.

2. Address Oil Leaks

Sub-step 1: Identify the source of the oil leak.
- Use the oil catch pan to collect any dripping oil.
- Clean the area around the leak with rags before applying any sealant or replacing components.
Sub-step 2: Replace damaged gaskets or seals.
- Remove any components that obstruct access to the gasket or seal.
- Replace the gasket/seal with a new one, ensuring a proper fit and applying gasket maker if required.
- Torque the bolts to the manufacturer's specifications (refer to service manual for specific torque values).

3. Replace Engine Oil (if necessary)

Sub-step 1: Drain the old oil.
- Place an oil catch pan under the oil pan, remove the drain plug, and allow the oil to fully drain.
Sub-step 2: Replace the oil filter.
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket on the new filter and install it hand-tight.
Sub-step 3: Refill with new oil.
- Replace the drain plug and pour in the manufacturer-recommended oil through the oil filler cap.
- Check the oil level with the dipstick and add oil as needed.
