As a car buyer for vehicles in any condition and with any mileage, even vehicles with engine damage have a value for us. In sales conversations with customers, statements often come up like, “The engine suddenly quit while I was driving,” or “I broke down with my car and then the roadside assistance found engine damage.” In most cases, the damage came abruptly to the customer and you didn’t know why. We usually ask again in more detail to be able to narrow down the extent of the damage and discover the following fascinating fact: Often, the engine has already announced that it is about to suffer engine damage by making abnormal noises. So that you can interpret these signs correctly and avoid an engine damage engine failure, we have compiled for you the Top 5 engine failure noises that can indicate engine damage. This way, you’ll be on the safe side and, if in doubt, you can visit a workshop before it’s too late – after all, better safe than sorry! Stay tuned and you’ll find that following this article, you’ll know better what to look out for.

Top 5 engine failure noises – That’s why they’re so dangerous.

When an engine is working properly and all the parts are in order, it usually doesn’t make any noise. You can hear the normal buzzing of the pistons in the cylinder and if you listen closely, you may notice a slight grinding in the alternator if it’s a new part. So far, so good. But if the engine starts to make itself heard with a clacking, squeaking or ticking noise, you should become alert and visit the workshop. Even though it may not be dramatic and can be taken care of with an oil change, unusual engine noises indicate a need for action. So that you do not rely on faulty interpretations, you can read in our article Bearing damage transmission noises to find out which damages in the transmission come from the same area, but have a different cause.

1. noises before the engine damage – the timing chain

Do you own a vehicle with timing chain, this takes over the timing of the camshaft. It usually requires very little maintenance and can last for many hundreds of thousands of miles. However, this is only the case if all parts of the engine are in perfect condition. If you have not had attached engine parts, such as the guide bar or tensioner, serviced regularly, the timing chain will also wear out. The result is engine damage – but this is usually foreshadowed. If the timing chain or the surrounding engine parts wear out, noises occur that indicate approaching engine damage. You should pay attention to whether you can hear a clacking noise from the engine compartment. This clacking is the first indication of wear of the surrounding parts. Now haste is required, after all, an engine damage which can be beyond the value of the car and thus lead to a total loss. 2.

2. noises of the valve tappets / hydro tappets can also be signs of a coming engine damage.

The valve tappets or hydro tappets are more of the small parts on the engine and together with the camshaft, they are responsible for the engine’s valve timing. They take up the slack between the camshaft and the valves and thus perform an important task for smooth engine running. If the valve lifters have a defect, this is usually manifested by a rattling/ticking noise. If this noise only occurs during cold starts, it is usually not a problem. However, if the noise persists, you should take action. For example, you can try to fix the noise by changing the engine oil, as too thin a consistency of oil can lead to this problem. If the noises do not disappear even then, engine damage could be on the way – worn valve lifters cannot compensate for the play. The consequences can range from misfiring to a defective catalytic converter to engine damage. Defective hydro/valve lifters in particular are often overlooked and considered not so bad. However, this approach is very negligent. So if you notice the symptoms described, it is best to visit a workshop directly or, as a precaution, call the breakdown service. The latter will also tow you to the nearest garage if necessary.

3. engine damage noises – the squeaking V-belt

Many car owners know it: Especially in winter some get the problem that it starts to squeak in the engine area. This can be an indication of material fatigue of the V-belt. This squealing is one of the sounds that can indicate impending engine damage. The V-belt is important for the following engine functions:

The V-belt drives the alternator and recharges the car battery while driving. If it is worn, it slips and can no longer perform this task 100%.
Another important function is to drive the power steering pump, which is important for power steering and thus for driving comfort.
So that you don’t sweat in the summer and have to resort to crank air conditioning (open window), the air conditioning compressor of the air conditioning system is also connected to the V-ribbed belt.

Clearly, these functions are important and especially the alternator is necessary for the operation of the entire vehicle. However, failures of these vehicle parts are only annoying and fixable. However, this changes when the wear of the V-belt causes the cooling water pump to fail. Its failure means that the engine no longer has cooling water flowing around it and can overheat. Engine damage or an engine fire can be the result. For this reason, you should take these squeaking noises from the fan belt seriously if you want to prevent engine damage.

4. nailing noises from the engine – a defective camshaft leads to engine damage.

The camshaft has the important function of controlling the engine and is subjected to very high loads. Over time and with frequent high engine speeds, these loads can cause the camshaft to bend, or wear out. Once this happens, a domino effect is set in motion in the engine compartment. This can lead to overloading of the crankshaft, breaking of the timing chain / timing belt, or even severe damage to the cylinders and pistons. The camshaft is driven by the crankshaft in a ratio of 2:1 and thus rotates at the same speed. This rotation causes the camshaft to open and close the valves in the correct sequence at exactly the right time. This ensures smooth engine running and long engine functionality. You can detect damage to the camshaft if you can hear a nailing noise coming from the engine compartment. In this case, you should directly call the nearest tow truck and have the vehicle driven to the workshop. Continuing to drive despite the nailing noise can cause a camshaft failure to turn into a major engine failure – so always be on the lookout for abnormal noises!

5. the crankshaft makes noises – this can be an imminent engine damage

The crankshaft is a particularly important element of the engine. It drives the camshaft and the connecting rods that move the pistons in the cylinders. At the so-called top dead center of the cylinder, the perfect interaction of the crankshaft and the camshaft at the perfect time causes a small explosion that pushes the piston back down, thus driving the crankshaft. If the crankshaft is defective, this is a massive problem for engine durability. If there is damage, however, it will announce itself with bright clack-clack noises that indicate engine damage is developing. Have you noticed crankshaft damage and would prefer to sell your vehicle? Here you will find our car purchase form. Simply have your vehicle appraised and secure the best price for your vehicle – even if it is making noises that indicate a budding engine failure.

What does engine damage sound like? These are the sounds that indicate it!

In the course of this article, you have now become acquainted with some noises that can announce engine damage. To help you keep track of the individual noises, here is a brief overview of the individual sounds and their origin. This means you are on the safe side, you can already give the specialist an initial suspicion and troubleshooting may not take as long. This saves the workshop’s working time and your wallet.

Engine damage noise: Clacking

Both crankshaft damage and valve/hydraulic tappet damage result in clacking (or click-clack) noises in the engine compartment.

Engine damage noise: Nailing

Caution. The camshaft is not functioning properly and can lead to engine damage if these noises occur. In the worst case, a defective camshaft can also damage the crankshaft and cause a capital engine damage.

Engine damage noise: Squealing

If there is a squealing noise in the engine compartment, this can be an indicator of high wear on the V-belt. The consequences range from a failure of the vehicle’s electrical system to engine damage caused by a defective cooling water pump. If you notice these noises, you can in most cases still drive to the workshop and avoid an avoid engine damage. However, if the indicator light comes on while driving, switch off the engine immediately and call the breakdown service! In most cases, you should immediately turn off the engine and call roadside assistance. For the most part, the sounds that the engine makes when it is defective indicate that engine damage is coming and should not be taken lightly. After all, engine damage isn’t just a disaster financially. It is especially important that you are safe on the road and not harmed by an ignored warning noise.

January 5, 2022 car repair & tuning guide, tips, products, info & co. What are the possible causes when the engine clatters, rattles, knocks or rattles? Also it is important to observe, when the clacking/rattling occurs. This can happen when the vehicle is moving, accelerating or idling. Knowing a clear cause of when exactly the problem occurs will help the workshop diagnose it more accurately. If the clacking occurs occurs after the clutch has been it can be seen that the noise is not caused by a defective dual-mass flywheel.

Continue driving with a clattering/clunking engine?

If the engine suddenly clacks, it is important that you visit a workshop as soon as possible in order to diagnose the problem. This can prevent costly damage, including engine failure.

Possible causes:

Check oil level: The oil level should be checked regularly, as it affects the wear and tear of the vehicle’s various components. This can help prevent the problem from occurring. If the oil level is too lowIf the vehicle is not running at full capacity, it is possible to top up the missing quantity yourself in accordance with the manufacturer’s approved specification. This is a cost-saving procedure, but if you are unsure and want to be on the safe side, you can also have it done in a workshop. This usually costs between 20 and 50 euros. The engine oil reduces friction and thus the wear of pistons, valves, shafts and bearings.

Hydro tappet defective: If hydraulic tappets (hydraulic tappets, hydraulic valve lash adjusters) are defective, they should be replaced, as they provide valve lash adjustment when in working order. In this case, the clacking of the vehicle should be heard from the engine compartment. Depending on the severity of the defect, it is sometimes sufficient to use a special hydraulic tappet additive or to change the engine oil. However, mechanically defective hydro tappets must be replaced.

Timing chain elongated: On vehicles with timing chains, the camshaft valve timing is usually driven by a timing chain. Wear of this chain can cause the valve to rattle or clatter when it is pressed. This problem exists, for example, in TSI and TFSI engines from the VAG Group: Volkswagen, Audi, Skoda, Seat.

Loose components: The clattering can also only be caused by only be caused by loose mounts or components in the in the engine compartment. This problem can be fixed by loosening the components or brackets. The cause of the problem can be, for example, the engine cover or the heat shield, which can cause clacking. Another cause of the clacking can also be loose cables can be another cause of the clacking. However, these causes can be easily fixed if they are accessible.

Valve clearance misaligned: Some vehicles do not yet have hydraulic valve lifters installed. If this is the case, then the valve lash must be adjusted manually at certain intervals. Manual adjustment of valve lash can take anywhere from 30 minutes to up to two hours.

Oil pump defective: The oil pump is an integral part of the engine and ensures the continuous flow and pressure of oil. If it is completely non-functional, it is very likely to cause engine damage, which can be costly. However, if the oil pump is only not working properly, or if the problem is a clogged oil strainerthen the lack of pressure can cause the engine to rattle. If, in addition to the rattling, the indicator light (oil can symbol) lights up, a workshop should be visited as soon as possible. If both occur at once, to prevent engine damage, the engine should be turned off and the car towed to the workshop.

Other causes that can be considered:

These are other possible causes that may be responsible for the rattle/clatter:

Another possibility could be the lateral impact of a piston on the liner, which is called a piston tipping known as piston tilt.
If you hear more of a “slap” instead of a rattle/clack, it could be a connecting rod bearing damage conrod bearing damage.
A defect of the crankshaft / camshaft bearing can be another possibility.
Components of the exhaust systemthat have come loose, which rattle, are also possible.
a broken catalytic converterwhose cell compound has separated into individual parts can also rattle.
rattling noises from auxiliary units, for example various pumps (water pump, vacuum pump, high-pressure fuel pump), can be the problem.
It could also be possible that its hood is not closing properly, which is why it then rattles while driving.

Are there any effects of a rattling/clattering engine on the main inspection?

The rattling often only affects the main inspection of the vehicle, if the exhaust emission test was not passed due to the specific damage. was not passed or if it is unusually loud and booming. Nevertheless, one should identify the cause and carry out an immediate troubleshooting to avoid an expensive engine damage.

Of course, that was far from it!

Noises from the drivetrain

Metallic clacking: Only shortly after starting – Possible cause: hydraulic valve lifters with insufficient oil pressure – Remedy: Not necessary, provided the noise disappears after a few seconds. If the clacking continues, a tappet is defective; off to the workshop. Grinding clutch noise: Audible when the pedal is depressed – Possible cause: defective release bearing – Remedy: replacement (workshop). Rattling or clattering Clutch: Audible only when idling – Possible cause: torsion springs of the driver plate broken – Remedy: Replace clutch immediately (workshop work). Rattling transmission: Noticeable noise when idling, difficult to distinguish from clutch rattling – Possible cause: large tooth backlash of the gear wheels, axial backlash of the shift sleeve – Remedy: Noise depends on the tolerance of the components and is usually harmless. Hitting noises: Can be heard and felt during load changes – Possible cause: Engine bearing loose or worn – Remedy: Retighten or replace the broken bearing. Howling and singing: Only noticeable when driving – Possible cause: worn bearings in transmission or differential – Remedy: replace. However, diagnosis is a matter for the workshop, as is repair. Ticking: Only audible when the engine hood is open – Possible cause: working noise of the injection nozzles – Remedy: not necessary. Buzzing: Immediately after switching on the ignition – Possible cause: working noise of the fuel pump – Remedy: not necessary.

Noise from chassis and brakes

Humming and roaring: Noticeable in curves – Possible cause: wheel bearing defective on one side – Remedy: first isolate the defect. If it hums in left-hand bends, a wheel bearing on the right is probably affected; if it hums on the right, the damage is likely to be on the left.. Exact diagnosis: jack up the car and turn the wheel. With the other hand, grasp the control arm or suspension strut. If vibrations can be felt there, the culprit has been found. Replacement is a matter for the workshop! Rattling in curves: Only audible when driving fast, especially during load changes and on wet roads – Possible cause: Noise originates from the control process of the ESP (the corresponding warning lamp lights up at the same time) – Remedy: Avoid the limit zone. Cracking and rumbling: Makes itself felt when cornering – Possible cause: The wheel-side joints on the drive shafts are defective – Remedy: Replace the affected axle shaft; diagnosis and repair is a matter for the workshop! Grinding and grinding: Only audible during braking – Possible cause: Carrier plate of worn brake pads grinding on brake disc – Remedy: Immediate replacement of brake pads, do not continue driving under any circumstances! Often a new brake disc is also due. Rumbling: Constant companion on bad roads – Possible cause: Usually defective rubbers on stabilizers, strut bearings or axle suspensions, possibly also shock absorbers themselves are affected. Diagnosis is a matter for the workshop! – Remedy: Replacement of the affected components. A matter for the workshop! Important: If you hear unusual noises from the suspension or brakes, go to the workshop immediately!

Disturbing noises in the interior

Rattling in the rear: Audible at every pothole – Possible cause: Tools, wheel nuts or other objects rolling around in the spare wheel well; the well is a large resonance body, acts like an amplifier – Remedy: Remove all loose objects; alternatively, wheel studs or tools can also be wrapped in rags or foam. Creaking: Can be heard when clutch is engaged – Possible cause: joints of pedal set run dry – Remedy: Lubricate joints with silicone spray. Do not use oil or grease, as this will damage the plastic pedals. Rattling in the dashboard: Usually only audible when driving, especially on bumpy roads – Possible cause: cable harnesses hitting ventilation ducts or other components – Remedy: Cover cables with soft foam or fix with cable ties. In today’s cars with their complex electronics and installed dashboards, this is usually a job for the workshop. Crackling noises: Often occurs in the area of plastic trim (doors, A-, B-, C-pillars) – Possible cause: plastic trim rubbing on the paintwork – Remedy: underlay contact points of plastic parts with felt strips. – Alternative: Lubricate with silicone spray or wax, then the surfaces slide more easily on each other. Squeaky seats: Regardless of the weight of the passengers – Possible cause: backrest adjustment or other connecting parts without lubrication – Remedy: lubricate the backrest adjustment. Sometimes, however, only total disassembly with subsequent lubrication of all connecting points helps (workshop work!). Droning door panels: Possible cause: The door loudspeakers cause the panels to vibrate. Remedy: Remove the door panels and check the loudspeaker mountings. Decouple the trim with foam mats (available from hobbyists) and install with new retaining clips. Crackling noises: This mainly affects the instrument panel and center console – Possible cause: Plastic panels rub against each other – Remedy: Place felt strips underneath to prevent rubbing noises. (Overview: All about repair and technology)

Noise from exhaust/underbody

Clanking/rattling from underneath: Possible cause: rubber mount of exhaust system torn – Remedy: install new rubber mount; possible on own initiative (pit/lifting platform required). Rattling and clattering from the center of the car: Can be heard both when accelerating and when coasting, often dependent on engine speed – Possible cause: defective catalytic converter (ceramic core broken) or heat shield plate cracked. – Also common: chambers of front or rear muffler have shaken loose – remedy: tap exhaust from front to back with fist blows. This makes it easy to expose the source of the noise (pit or lifting platform required). Replace defective part. Clanking or jingling: When engine is running, often audible even when stationary – Possible cause: Loose or broken clamps – Remedy: Visual inspection or knocking; tighten loose clamp, replace broken parts. Hissing, blowing noises: Mostly from the engine compartment area – Possible cause: hairline cracks in the exhaust manifold – Remedy: Replace manifold (workshop).

Body noises

Loud cracking noise: Mainly when driving over potholes – Possible cause: dry door latches – Remedy: adhesive lubricant on door latch and closing mechanism eliminates the cracking noise. Humming: Usually only heard at higher speeds – Possible cause: plastic trim on bumpers or underbody panels has become loose and flutters in the airstream – Remedy: check corresponding components for tight fit and, if necessary, fix properly again. Whistling or hissing: Possible cause: wind noise caused by doors hanging crookedly and no longer closing properly, or damaged door seals – remedy: align the door hinge plates on the A-pillar (requires a lot of experience). – For professionals only: Gently bend the window frame inward with the window down so that the seals are tighter against the body and thus seal better. Constant creaking and squeaking: Noise usually comes from the area of the doors and sunroof – Possible cause: dry and brittle seals on doors and sunroof. Doors and roof skin act like large resonators, amplifying the noise and making it difficult to localize – remedy: lubricate all seals regularly with a silicone-based care product and keep them supple. Rattling windshield wipers: Occurs especially in light rain – possible cause: hardened wiper rubbers – remedy: replace wiper blades.
