Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Oil Change

Sub-steps:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
3. Replace the oil filter with a new one.
4. Reinstall the drain plug and torque it to the manufacturer’s specification (typically around 30 lb-ft).
5. Refill the engine with the recommended oil type (typically 0W-20 for Honda vehicles) using a funnel.

3. Valve Train Inspection

Sub-steps:
1. Remove the valve cover by unscrewing the bolts (torque to specification when reinstalling).
2. Inspect rocker arms and valve springs for wear or damage.
3. Check for proper oil flow to the valve train; clean any sludge or debris.
4. If necessary, replace damaged components (rocker arms, lifters, etc.).

4. Reassemble and Test

Sub-steps:
1. Reinstall the valve cover and torque bolts to the specified value.
2. Reconnect the negative battery terminal.
3. Start the engine and listen for the ticking noise. Observe if it has reduced or stopped.
