Has your car engine been making strange noises? If so, the organizers of Charlotte, NC’s largest auto show say the sounds could be indicative of a bigger issue. As the brains behind Charlotte AutoFair, they have a deep understanding of car-related matters. 

Here are a few insights from the auto show organizers on car engine noises and what they potentially mean:

  • Clicking: If this sound occurs when you’re driving slowly, you may have a faulty hydraulic valve lifter at hand. Alternatively, car engines produce a clicking noise when the gap between the valve tappet and rocker arm is wider than recommended. You may also hear a similar noise when accelerating your car, in which case the cause is damaged or loose rings or pins in the piston. To get a clear idea of the problem, get your car inspected by a professional mechanic.

  • Metallic Knocking: When you hear a knocking sound originating from your engine, there is likely a problem with the alignment of the connecting rods. In most cases, the noise becomes apparent when you’re driving at a steady speed. If the knocking becomes louder during acceleration, your car’s crankshaft may be the culprit. In this scenario, Charlotte’s leading car exhibit hosts suggest checking the rod and thrust bearings.
  • Backfire: A backfiring engine never means good news, especially if it happens while pressing the gas pedal. The most common reason for an engine to backfire is a damaged valve or camshaft. Additionally, misplaced spark plug wires and timing issues with your ignition or camshaft belt can also cause the loud pop sound. Because backfiring engines can set your hood on fire, the auto show experts at Charlotte AutoFair emphasize consulting a car specialist immediately.
