    What are the top 5 signs of engine trouble?

    5 Warning Signs of Engine Failure

  • Knocking Sound. That repetitious knocking or tapping sound may well be an indication that you’re low on engine oil.
  • Loss of Power.
  • Excessive Amount of Exhaust Smoke.
  • Vibrating.
  • Worsening Gas Mileage.
  • What noise does a blown head gasket make?

    If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
