Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.
Ensure the engine is cool before starting the inspection.

2. Check Engine Oil

Using a dipstick, check the oil level; if low, top off with manufacturer-recommended oil type.
If oil is dirty or has not been changed recently, drain and replace the engine oil and oil filter.
- Tools Required: Oil filter wrench, socket set, oil catch pan, funnel.
- Safety Warning: Hot oil can cause burns; allow engine to cool before proceeding.

3. Inspect Engine Components

Visually inspect all accessible engine components for loose bolts, particularly around the valve covers and timing components.
Tighten any loose bolts to manufacturer specifications.
- Tools Required: Socket set, torque wrench.

4. Check Timing Chain/Belt

If the ticking sound persists, remove the timing cover (if applicable) to inspect the timing chain/belt for wear.
- If worn, replace the timing chain/belt and tensioners per manufacturer guidelines.
- Tools Required: Socket set, screwdrivers, timing tool set (if required).

5. Exhaust System Inspection

Inspect the exhaust manifold and connections for any cracks or loose fittings that may produce a ticking noise.
If any damage is found, replace the affected components.
- Tools Required: Wrench set, exhaust gasket set.
