Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil filter wrench, engine oil, new spark plugs (if needed), OBD-II scanner.
Ensure the engine is cool before starting work.
Disconnect the battery to prevent electrical shorts.

2. Check Engine Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Reinsert and remove the dipstick to check oil level.
3. If low, top off with the appropriate type of engine oil (check owner’s manual for specifications).
4. If oil is dirty or has debris, consider an oil change.

3. Inspect Valve Train Components

Sub-steps:
1. Remove the valve cover using a socket set.
2. Inspect the rocker arms, lifters, and push rods for wear or damage.
3. If any components are worn, replace them with OEM parts.
4. Reassemble the valve cover using a torque wrench to the manufacturer's specified torque (usually around 7-10 ft-lbs).

4. Replace Spark Plugs (if necessary)

Sub-steps:
1. Remove the ignition coils using a socket set.
2. Unscrew and remove the old spark plugs with a spark plug socket.
3. Install new spark plugs, ensuring they are gapped correctly (typically 0.043 inches).
4. Reinstall the ignition coils.

5. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Start the engine and listen for the ticking noise.
3. If the noise persists, consider further inspection of the timing chain/belt.
