Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, mechanic's stethoscope, torque wrench, engine oil.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery before starting any work.

2. Check Engine Oil

Remove the engine oil dipstick and wipe it clean.
Reinsert the dipstick and check the oil level; add oil if low.
If oil is dirty or old (over 5,000 miles), proceed to change the oil and filter.
- Sub-steps:
  1. Place a drain pan under the oil pan.
  2. Remove the oil drain plug using a socket set.
  3. Allow the oil to drain completely.
  4. Replace the drain plug and torque to the manufacturer’s specification (typically around 25 ft-lbs).
  5. Remove the old oil filter using an oil filter wrench.
  6. Install a new oil filter, lubricating the rubber gasket with new oil.
  7. Fill the engine with new oil as specified in the owner's manual (typically 5W-20 or 5W-30).

3. Inspect Engine Components

Visually inspect for loose or damaged components.
- Sub-steps:
  1. Check engine mounts for signs of wear or damage.
  2. Inspect heat shields and exhaust components for looseness.
  3. Tighten any loose bolts or screws on engine accessories.

4. Address Timing Chain/Belt

If the noise persists, check the timing chain/belt tension.
- Sub-steps:
  1. Remove any necessary covers to access the timing chain/belt.
  2. Inspect the tensioner for proper operation; replace if defective.
  3. If the belt/chain is worn or stretched, replace it according to service manual instructions.
