Engine Noises That Require Immediate Attention

Posted on October 28, 2019

From knocks and clicks to groans and ticks, all cars start to develop engine noises at some point, especially if they’ve gotten a few years old. But what if you’re sitting in traffic or driving along serenely, and your engine starts making a noise which sounds much more sinister than normal wear and tear? What do you do?

The best thing to do is to take it to a reputable auto shop ASAP, especially if the car in question is a high-end European one such as a Mercedes or an Audi. Weird engine noises can signify anything; from a minor problem such as a loose bolt to a major one that requires a complete engine overhaul. If it’s the latter, you don’t want to take any chances with your high-end European vehicle that can make the problem worse. Here are some engine noises which you should never ignore.

Engine Hissing

In most cases, a hissing noise from the hood signifies an overheated engine. However, engine hissing can also be caused by a clogged up exhaust system or catalytic converter. The worst-case scenario is a vacuum leakage. Whatever the reason, set up an appointment immediately to diagnose and repair the problem. Not only will a blown engine cost you thousands of dollars to fix, it poses a major safety risk.
As the transmission is the vital component that transmits the engine’s power to the wheels, any strange noises should be taken seriously. Grinding noises while shifting gears are often accompanied by the car jerking and shaking. It could be a simple case of low transmission fluid, but it could also point to something more serious, such as a damaged clutch or shift linkage. Ignoring grinding noises from the gearbox can lead to transmission failures, and we don’t need to tell you how expensive it can be to repair or replace a transmission.

Popping Exhaust

While a popping exhaust generally indicates that there are holes in the muffler, it could also point to a leak within the fuel injector. This is a serious problem that requires the immediate attention of a professional mechanic. Exhaust leaks should be taken seriously as they can cause the fuel economy and the emissions ratings of your vehicle to worsen. If the problem is left unattended for a prolonged period, it can also result in engine damage.

Knocking Noise

There a number of significant engine problems that can cause a knocking noise to issue from your hood. If the noise is a fast-paced clatter coming from the top of the engine, it could be the valves. This will require you to get some work done on your engine’s cylinder head. If it’s a steady metallic ticking, it could anything from loose rocker arms to a worn out camshaft.
