Solution

1. Preparation

Gather tools and parts: Have an OBD-II scanner, socket set, torque wrench, and a stethoscope ready.
Ensure safety: Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Change Engine Oil

Drain the old oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow the oil to completely drain.
Replace oil filter:
- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a thin layer of new oil to the rubber gasket of the new filter before installation.
- Install the new oil filter by hand, ensuring it is snug but not overtightened.
Add new oil:
- Replace the drain plug and torque it to the manufacturer’s specifications.
- Using a funnel, add the specified amount and type of new engine oil through the oil filler cap.

3. Adjust Valves (if applicable)

Remove valve cover:
- Detach any components obstructing access to the valve cover.
- Remove the valve cover bolts and lift the cover off.
Inspect and adjust the valves:
- Use a feeler gauge to measure the valve clearance.
- Adjust as necessary by tightening or loosening the adjustment screws according to the service manual specifications.

4. Inspect and Replace Timing Chain/Belt (if necessary)

Remove necessary components:
- Disconnect and remove any belts, pulleys, or accessories obstructing access to the timing chain/belt.
Inspect the timing chain/belt for wear or damage.
Replace with a new timing chain/belt following manufacturer specifications, ensuring proper alignment and tension.

5. Reassemble and Test

Reinstall the valve cover securely with new gaskets if necessary.
Reconnect any components removed during the repair.
Reconnect the battery and start the engine to test for the ticking noise.
