Strange noise from the engine? These are the most common causes
A strange noise from the engine is rarely cause for panic, but always a reason to listen carefully. Each type of noise points to a different possible cause. We list the most common noises and what they mean.
Ticking noise
A ticking noise that follows engine speed often indicates low oil level, worn valves, or timing chain issues. First check the oil level, and have a diagnosis carried out immediately if the noise persists.
Squealing or whining noise
A high-pitched squeal on start-up or acceleration often points to a worn drive belt or a loose belt tensioner system. This is usually simple and affordable to fix if caught in time.
Rumbling or humming noise
A deeper, rumbling noise that increases with speed can indicate a wheel bearing or drive shaft issue. This needs further investigation, as it can affect driving safety.
Knocking noise under acceleration
This can indicate engine knock from incorrect fuel, a dirty injector, or an ignition problem — a common signal especially on older engines.
