Solution

1. Preparation

Gather all tools and parts required for the repair.
Ensure the engine is cool before beginning work.
Disconnect the battery to prevent electrical shorts during repairs.

2. Change Engine Oil and Filter

Tools Required: Oil filter wrench, socket set, drain pan, funnel
Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Place a drain pan under the oil pan and remove the oil drain plug to drain the old oil.
3. Remove the old oil filter using the oil filter wrench.
4. Apply a small amount of new oil to the rubber gasket of the new oil filter and install it.
5. Reinstall the drain plug and torque it to the manufacturer’s specifications.
6. Fill the engine with the recommended type and amount of new engine oil.

3. Check and Replace Damaged Components

Tools Required: Socket set, torque wrench, various hand tools
Sub-steps:
1. Reinspect engine components identified during the visual inspection.
2. Replace any damaged or worn components, such as engine mounts or timing components.
3. Tighten all bolts and fasteners to the specified torque values as per the service manual.

4. Engine Noise Assessment

Tools Required: Stethoscope or mechanic's listening device
Sub-steps:
1. Start the engine and use the stethoscope to pinpoint the source of the knocking noise.
2. If the noise is coming from a specific component (e.g., timing chain or belt), remove that component for further inspection or replacement.
