Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working.

2. Check Engine Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If the oil level is low, top off with the manufacturer-recommended oil type.
If the oil is dirty or has not been changed in a while, proceed to change the oil and filter.

3. Inspect and Tighten Components

Inspect engine mounts for any signs of wear or damage; replace if necessary.
Check belts for proper tension and wear; replace if frayed or loose.
Tighten any loose bolts and nuts on engine components.

4. Examine Exhaust System

Inspect for any visible cracks or holes in the exhaust manifold or pipes.
Replace any damaged exhaust gaskets or components.

5. Check for Internal Engine Issues

If the noise persists, consider performing a compression test to evaluate engine health.
If compression is low, further disassembly may be necessary to identify internal damage.
