Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, mechanic's stethoscope, oil catch pan, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent any electrical issues while working.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil drain plug and drain the old oil into an oil catch pan.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque to the manufacturer's specifications.
4. Add new engine oil as specified in the owner's manual.

3. Inspect Valve Components

Sub-steps:
1. Remove the valve cover by unscrewing the bolts with a socket set.
2. Inspect for any broken or loose components such as rocker arms or push rods.
3. Replace any damaged parts and reassemble the valve cover, ensuring proper torque on the bolts.

4. Check Exhaust System

Sub-steps:
1. Visually inspect the exhaust manifold and connections for any cracks or holes.
2. Repair or replace any damaged components in the exhaust system to eliminate ticking sounds.

5. Inspect Timing Belt/Chain

Sub-steps:
1. Remove any components obstructing access to the timing cover.
2. Check for wear, stretching, or misalignment of the timing belt/chain.
3. Replace the timing belt/chain if it shows signs of wear or damage.
