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.
