You start to drive and all of a sudden you hear your engine clicking. And you just had to ask yourself, can you drive with engine clicking? Engine clicking may come from different sources or may be caused by different things. Depending on what that reason is — that’s how you know if you can continue driving with an engine clicking. The clicking sound in your engine could be typical due to the engine's design or it could just be the result of natural wear from using your engine. But if it’s something more serious then you are not totally safe to drive. So once you hear that engine click best to inspect it as soon as possible.

What does a ticking engine sound like?
It should be very rhythmic and sound like a sharp pencil tapping on a desk. The ticking of the injectors is not a problem, and is to be expected and you may drive with confidence. If you have a fuel-injected vehicle, the tick may be typical. It's possible that the sound you're hearing is the sound of your injectors firing. Your fuel injectors are little valves that open and close quickly, allowing fuel to be injected with the air that your engine draws in.
A mild clicking from the valves is also considered “typical wear.” The camshaft, pushrods, lifters, spring-loaded rocker arms, and valves themselves make up the valvetrain. Without a valvetrain of pushrods and lifters, the cam lobes make direct contact with the valve stems in an overhead cam engine, however there will be chains to drive the camshafts.
Even when you just drive to the store and return, all of these parts move hundreds of thousands of times. When fresh, these components move extremely short distances and are tightly and precisely assembled, but it's natural for them to loosen and wear over time.
If it’s not those things — the first thing you have to do when you hear your engine clicking is check the oil level. That is the most common reason for an engine clicking. This is a sign that the lubrication of critical engine components is insufficient. If the oil level is low, the ticking could indicate that upper engine components like the camshaft and valvetrain are starved for oil, in which case you should add oil immediately to avoid major damage and figure out why you're low on oil in the first place (leak, oil consumption, etc.).
Another possibility is that there is an oil pressure issue. This could be due to a faulty oil pump, a clogged/obstructed oil filter, or a sludge or debris clog on the pickup screen of the oil pump. Poor oil pressure indicates that the entire engine is deficient in oil, and it is a problem that must be handled immediately.
Also, tick could be caused by a leak in the exhaust manifold. Because the vapors contain carbon monoxide, driving with an exhaust leak can be deadly. An exhaust leak can reduce fuel efficiency, making your engine work harder and requiring you to fill up your tank more frequently.
Is it safe to drive car with clicking noise?
Can you drive with engine clicking? Yes you probably could technically. But is it safe to drive a car with clicking noise? Again, it depends on the source of that clicking sound. Other than the engine, clicking noise can also come from the wheels and it will not be safe to drive.
Strange noises coming from your wheels can be rather alarming. It just takes one significant wheel problem to render your automobile dangerous and undriveable, so unusual wheel noises are understandably concerning. Clicking and popping from the steering wheel, like other strange noises from your car, should encourage you to arrange an inspection right soon.
Even while the clicking sound may appear to emanate from your wheels, this is rarely the case. Your vehicle's steering system is a complicated system with numerous moving elements, and many of these components might create weird noises such as clicking.
A fractured CV joint is the most typical source of a clicking or popping sound from the wheels. The joints are located at the front end of the front axle and provide the flexibility that the axle requires as the wheels and suspension move. When a CV joint is destroyed, the axle loses flexibility and makes a continual clicking noise as the wheels revolve.
The struts, which are an important part of your suspension system, could also cause a clicking sound. The suspension is unable to absorb the majority of the road's force when the struts are damaged or blocked. This is not only bad for your car, but it also makes a peculiar noise coming from the wheels.
When your hubcaps' lug nuts go loose, the hubcaps have wiggle room and wobble when you travel at high speeds or make turns. This shaking produces a rattling sound that you can generally hear from inside your vehicle's cabin. Clicking sounds can also be caused by a loose drive belt or tensioner, as well as unevenly shaped or inflated tires.
When a car makes popping or clicking noises near the steering wheel, it could indicate a significant problem. Continuing to drive a car with damaged struts or CV joints may cause more damage and make the vehicle unsafe to drive. If you hear noises in your car that you aren't acquainted with, you should arrange an inspection right away.
If the clicking is coming from the engine, the noise could be originating from a variety of sources. Again, it is important to know the very source to make a judgement and answer the question, can you drive with engine clicking? Because sometimes it is not only a matter of safety but also a matter of causing more damage to your engine leading to very expensive repairs.
Can you drive with engine clicking? Yes, but you may end up damaging more car components. Like for example, when you drive with bad lifters. Check your lifters if you hear any ticking, tapping, or clicking noises from the engine. Do not ignore this sound since the consequences of ignoring it might be severe and costly. If your lifters are bad, you should not drive your vehicle for more than 100 miles.
Sometimes lifter click is simply caused by dirt in your engine oil, by low oil levels or poor lifter spacing, or malfunctioning lifters in general. It will be fixed by changing the engine oil, cleaning the lifter with oil additives, adjusting the lifter spacing, and, in rare situations, replacing the complete lifter to eliminate the ticking sound.
But when you drive on defective or collapsed lifters for an extended period of time, the inside section of the lifters might collapse all the way to the point where they contact the camshaft, damaging the camshaft. When a lifter fails, the interior piece of the lifter might deteriorate all the way down to where it contacts the camshaft. As a result, the lifter's roller rubs against the camshaft, potentially damaging it to the point that your camshaft will need to be replaced in the next 10,000-15,000 miles.
A clicking noise from the engine is the most evident indicator of a damaged or failing lifter. The ticking noise made by the lifter can be intermittent or constant. It's easy to notice because it's distinct from the rest of the engine noise.
Another engine clicking source of problem that is serious has something to do with a bad rod. A harder knocking sound that becomes louder as the engine RPMs increase could indicate a rod or main bearing knock. The connecting rods of the pistons use bearings to link to the crankshaft, and these bearings can develop “slap” and wear to the point where they loosen up at the crankshaft in the event of extreme wear or low oil levels.
The primary bearings for the crankshaft can also acquire the same issue, which is a problem that will not go away on its own. That tick or knock will eventually increase to the point where it sounds like someone hammering a metal garbage-can lid, and there will be only one solution: a total engine rebuild. When the engine is running, a continual loud rod knock sound is a symptom of severe wear/damage.
With a bad rod, can you drive with engine clicking? Certainly not. You need to address this significant issue immediately. The piston rod connects the piston to the crankshaft and is supported by a large set of ball bearings. Starting with a gleaming iridium surface that is put on a soft metal called babbit compound, the bearings are constructed in layers of various materials.
The strong steel bearings will swiftly cut into the crankshaft surface after the babbit compound is worn away, causing a knocking noise. At the same time, the oil pressure inside the engine drops dramatically as a result of the loose bearings allowing too much oil to escape through the crankshaft's oil distribution channels.
The first step in reducing the deterioration is to thicken the oil viscosity and increase the oil pressure inside the engine. Oil thickening products abound at auto parts stores. STP Oil Treatment is the most well-known, but there are many more. Start with one can, and if that doesn't work, add a few more. Once the oil has thickened, you should use caution while starting the engine from a cold start, allowing the engine to warm up before driving away.
Also go easy on your acceleration. On the motorways, the highest load on a worn piston rod occurs during heavy acceleration, so keep your foot soft on the pedal and maintain your top speed. Finally, because the engine is likely to be contaminated with metal particles from aging bearings, maintain your oil clean.
Car Won’t Start With Clicking Noise
You know the feeling: you've been rushing all morning and are late for work. You run to the car, buckle up, and turn the key, only to hear a clicking sound instead of the engine starting. It could mean different things according to the kind of clicks you hear:
One single – A click usually indicates an electrical problem. The trouble is that your engine's electrical fault could be caused by a variety of components. There are two types of clicks you could hear — a single click with no engine turnover and secondly, a fast clicking. While there is no straightforward “diagnose from the noise alone” situation, the difference between fast and slow clicking can provide us some insight into the problem and its severity.
Series of Quick Clicks – if your car makes a series of rapid clicks when you turn the key in the ignition, it could be an easy problem to remedy. A quick clicking noise is usually an indication that your starter motor isn't getting enough electrical current to engage – or your solenoid is attempting to engage but failing to connect. A deteriorating battery, a poor connection at the battery, or even a malfunctioning alternator that isn't correctly recharging your battery could all be to blame for the lack of electrical current. In the best-case scenario, your batteries or posts are dirty.
Single Click When Trying To Start – If your car makes a single loud click when attempting to start, especially if you only hear one click, some mechanics will quickly blame your starter engine. However, it's still possible that the problem is caused by a filthy, corroded, or exhausted battery.
When I accelerate I hear a ticking noise?
Many things can generate a ticking noise when accelerating. It's critical to identify the source of the problem because there's a chance the engine will be damaged, increasing the repair expense. Oil pressure, exhaust leaks, spark plugs, or the valvetrain are the most common causes.
Can you drive with engine clicking? The answer really depends. But one thing is for sure, you must never drive with an engine clicking without first ruling out any possible serious causes for that clicking sound.
