Noise from Engine or Exhaust Inspection

Your engine is designed to make quite a lot of noise. While some of those “noises” can be music to your ears like a finely tuned V-12 engine or the exotic exhaust notes, others are just cries for help. Some car manufacturers go as far as to put speakers under your dash to simulate these beautiful sounds.

The “bad noises” may include the jolt of a backfire, snake-like hisses, clunking or thumping noises, or the continuous tapping sound of a non-functioning lifter.

These noises are the car’s way of telling you that it needs help. There is a repair job almost always attached to these noises.

What are the Common Reasons of Noise from Engine?

Here is a list of some noises and their probable causes.

• Whirring
  It is caused by typically by the belt driven equipment or the belt itself.

• Hissing, Gurgling or Sizzling
  These sounds are mostly caused by an overheating engine.

• Loud Exhaust Note
  A broken muffler or exhaust pipe is most likely the culprit here.

• Backfires
  The most common reason for this is the presence of moisture or water in the fuel system.

• Sputtering
  This noise is caused by an incomplete combustion event. While this noise does not last, but it has the potential to cause serious damage to your engine.
  A blocked or a faulty fuel injector can also cause the sputtering in your car. In some cases, it is also accompanied by a constant clicking noise.

• Tapping or Clicking
  This noise is most probably caused by low oil pressure, excessive clearance of the valve, or faulty hydraulic valve lifter.

• Spark Knocking
  Improper ignition timing, unbalanced air/fuel ratio, improper octane level, or overheating is the cause of these types of noises.

• Bearing Knock
  Excessive main bearing clearance and worn rod bearing can cause such noises.
