Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, level area with the engine cool.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Check and Replace Engine Oil

Tools Required: Oil filter wrench, socket set, drain pan
Remove the oil drain plug and allow the oil to drain completely into the pan.
Replace the oil filter using the oil filter wrench.
Reinstall the drain plug and tighten to the manufacturer’s specifications (typically around 25-30 Nm).
Fill the engine with the recommended oil type and capacity (check owner's manual).

3. Inspect and Adjust Valvetrain Components

Tools Required: Torque wrench, socket set, feeler gauge
Remove the engine covers to access the valvetrain.
Inspect rocker arms and lifters for wear; replace any damaged components.
Adjust the valve clearance to the manufacturer's specifications using a feeler gauge.

4. Inspect Timing Components

Tools Required: Torque wrench, socket set, timing tool kit (if necessary)
Remove the timing cover to access the timing chain/belt.
Inspect for wear or damage; ensure proper tension and alignment.
Replace the timing chain/belt if worn or if the noise persists.

5. Reassemble and Reconnect

Reinstall all components in reverse order of removal, ensuring all bolts are tightened to specifications.
Reconnect the battery terminal and ensure all connections are secure.
