Most Common Reasons for a Louder Engine
As mentioned earlier, there can be various reasons that are making the engine make more noise than usual, that we are listing down here:
Damaged Muffler: Over a certain period of time and usage the muffler of the car engine will start accumulating rust leading to several holes and cracks. That way it will completely fail to musk the engine noise, and so you hear a louder than normal noise, as the engine runs.
Faulty Catalytic Converter:Sometimes, if the catalytic converter of the engine fails to burn off the newly generated hydrocarbons accumulated near the exhaust, it will stop the car from running but before that it will make it sound louder than usual.
Tail Pipe Broken Down:If the tailpipe starts rotting and develop holes, it will increase the levels of noise in the car engine.
Worn Out Seals and Gaskets:After a vehicle has run for years together and crossed a certain number of miles, theseals and gaskets of the exhaust system will start wearingout causing the engine to make louder noise and also sputter some times.
Failing Oxygen Sensors: A failing oxygen sensor will tend to send wrong data, which will lead less or more amount of fuel reach the engine making it run roughly and loudly than usual.
Faulty Spark Plugs:If the spark plugs of the engine becomes dirty or faulty, it can cause the ignition system to misfire and that will make the engine to run louder.
Blocked Sensor of the Mass Airflow:Sometimesthe mass airflow sensor can dirty and get blocked which will finally result in sending wrong amount of fuel passing through the injectors, leading the engine to experience rough running with more sound coming out than normal.
Why Servicing a Louder Engine is Important
Most of the above mentioned parts are components of the exhaust system, the failure of which will not only make a vehicle engine run louder but will make it dangerous to drive as well.
