Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.

2. Check Engine Oil

Check the oil level using the dipstick.
If oil is low, top off with the recommended oil type specified in the owner's manual.
If the oil is dirty or has not been changed for a while, consider performing an oil change.

3. Inspect and Tighten Components

Visually inspect all accessible engine components, including valves, covers, and exhaust manifolds.
Use a torque wrench to tighten any loose bolts or nuts found during inspection to the manufacturer's specifications.
Replace any damaged gaskets or seals that could be causing noise.

4. Examine Exhaust and Drivetrain

Inspect the exhaust system for any loose connections or signs of damage; replace any faulty parts as necessary.
For the drivetrain, check CV joints and universal joints for play or wear, replacing them if necessary.
