Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, engine oil, oil filter wrench, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical shorts or accidents.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil filler cap and dipstick to access the oil.
2. Use the OBD-II scanner to check for oil pressure codes.
3. If oil is low or dirty, drain the oil using an oil pan and wrench to remove the drain plug.
4. Replace the oil filter using an oil filter wrench.
5. Refill the engine with the recommended oil type (refer to the owner's manual for specifications).
6. Start the engine and check for leaks; ensure the knocking noise has diminished.

3. Inspect and Replace Engine Components

Sub-steps:
1. If the noise persists, inspect the timing chain/belt and tensioners for wear.
2. Remove any necessary covers to access the timing components.
3. Replace any worn or damaged timing components, ensuring proper alignment.
4. Inspect the valve train assembly for any loose components or signs of wear.
5. Reassemble covers and components, ensuring all screws are torqued to specifications.

4. Verify Engine Functionality

Sub-steps:
1. Reconnect the battery and start the engine.
2. Monitor the engine for any unusual noises or warning lights.
3. Take the vehicle for a test drive to ensure it operates smoothly without knocking.
