Why Your Car’s Engine Is Making a Rattling Noise

Are you hearing a rattling or pinging sound from your car? Is the noise coming from the engine area? An engine rattling noise can be a sign that something is wrong, and should be addressed as soon as possible. Let’s take a look at some possible reasons why your car’s engine is making unusual sounds.

A Rattling Noise from the Engine When Accelerating

Noises coming from the engine when you are pushing on the gas could be caused by a loose or weak timing belt, chain tensioner, cracked flywheel, or a broken flexplate.

These issues will only get worse over time, not better.  It is important to bring your car into the repair shop as soon as possible.

Noises Coming from the Engine When Idling

A common problem that may be causing a rattling noise while idling involves the engine’s hydraulic valve lifters. This part of your car is responsible for opening and closing the engine’s intake and exhaust valves.

When a lifter is not working properly, a loud ticking sound can usually be heard under the hood.

Another issue that could be causing a rattling noise at idle is piston slap. If one or more of your pistons no longer fit properly in the cylinders due to wear, piston slap can occur. This is something that should be checked out right away. 

Engine Noises Happening When the Car Is Hot 

An engine ticking noise when the car is hot could indicate low oil pressure. Insufficient oil pressure can be damaging to an engine regardless of its age, so having a qualified mechanic take a look at it is highly advisable.
