Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, torque wrench, mechanic's stethoscope.
Safety: Disconnect the battery to avoid any electrical shorts while working.

2. Oil Change (if necessary)

Drain the old oil:
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug using a socket set and allow oil to completely drain.
Replace oil filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new oil filter with clean oil and install it hand-tight.
Refill with new oil:
- Replace the drain plug and tighten to manufacturer's torque specification.
- Add new oil through the oil filler cap, using the specified oil type and amount.

3. Valve Adjustment (if applicable)

Remove the valve cover:
- Unbolt the valve cover using a socket set and carefully lift it off.
Inspect and adjust the valve clearance:
- Use a feeler gauge to check the clearance between the rocker arms and valves.
- Adjust the clearance according to the specifications in the service manual using the appropriate tools.
Reinstall the valve cover:
- Clean the mating surface and apply a new gasket if necessary.
- Bolt down the valve cover to the specified torque.

4. Address Other Possible Issues

Replace faulty components:
- If the ticking noise is coming from the timing belt or accessory belt, replace the affected belt.
- Inspect and replace any damaged pulleys or tensioners.

5. Reassemble and Reconnect

Reconnect the battery and ensure all tools are removed from the engine bay.
