Is It Worth Fixing a Rear Main Seal

Any unusual sound coming from the engine, like a clicking noise, can be concerning to any car owners. Most especially if it has been going on for some time. You may start to ask, “Can engine clicking be fixed?” The answer would be yes. And it’s not always something to be worried about. A simple oil change may resolve it in no time. But there are also instances when that clicking could come from faulty car parts that are connected to your engine.

⚠️ If It's Broken, Don't Fix It - Get Paid Cash for Your Vehicle ⚠️


When something goes wrong with one of the components that make up an engine or is connected to the engine, clicking noises can be heard. The clicking noises are most noticeable whether the car is moving, accelerating, idling, or starting up. We will walk through all the possible causes of engine clicking and solutions as the answer to the question, “Can engine clicking be fixed?” depends on the cause.


Is it bad if my engine is ticking?


It's likely that you've never even noticed these common engine clicking noises until your vehicle is left to idle in a confined place where the sounds are amplified. The following are a few of the most typical causes of ticking noises coming from beneath your car's hood that are perfectly normal and don't require any of your attention. Such sounds come from the purge valve, PCV valve and the injectors.


What about the purge valve? Because as the purge valve in the engine is working by discharging stored gases from the charcoal canister into the intake, where they are then burned a clicking noise is frequently produced. So the engine ticking or clicking could really be just the purge valve working,


What about the PCV valve? The engine's PCV valve really just ticks or clicks every now and then. It could be just a symptom that the PCV valve is aging. That is also hardly something to be concerned about. Can engine clicking be fixed? For this one, you just need to replace the PCV valve if the clicking sound is starting to annoy you.


What about the injectors? Engine clicking can occur, and depending on the design of your engine, it is occasionally natural. The clicking sound you may hear when driving a car with fuel injectors is typical. These injectors are referred to as portable electric valves because they open and close quickly to allow the proper amount of fuel to enter the internal combustion chamber. When these injectors open and close while idle, you may hear a clicking sound.


An engine's fuel injectors frequently generate a ticking or clicking noise so when the noise comes from this area it’s no cause of concern. Fuel injectors are electronically controlled and produce a ticking or buzzing noise when in use.


So is it bad if my engine is ticking? No. It’s not necessarily bad because in some instances it could mean that your engine or its components are just working as it should, producing the engine clicking sound.

What causes engine clicking?



  • Engine clicking could be caused by low oil pressure or low oil level.


Because gravity will keep any oil deeper down in the engine if the system has insufficient oil or oil pressure, the engine's top end may suffer as a result. When this happens, the oil will not reach the top of the engine, and you will begin to hear engine clicking or ticking noises as the components are not adequately lubricated.


The solution entails monitoring the oil level in your vehicle. When checking your car's oil, make sure it's on level ground. Then locate the oil dipstick, pull it out, wipe any oil off, replace it, then pull it out once again. On the dipstick, you should be able to view your oil level. A healthy oil level should be near to, but not quite at, the maximum. Fill up the oil tank if it's running low.


You must identify why your oil level is low, in addition to filling it up. Look under the car and under the hood for any leaks. Look for dripping oil or little oil patches. If you detect small drops of oil on your driveway, have it checked right away because it could indicate a much larger leak somewhere else.


You can then check your oil pressure if your car's oil level is satisfactory. You'll need to use the oil pressure gauge in your dashboard's instrument cluster to accomplish this. When the engine is idling and heated, make sure it registers at least 15-20 psi. If your car has an oil pressure gauge that doesn't have numbers, make sure it stays green. Check the oil level right away if the needle is in the red.


  • Part of the engine is stuck.


When engine parts become stuck or worn, it's usually because they've been deprived of oil. This is what causes the engine to click when it happens. Excessive play between the connecting rod and the crankshaft might cause the noise. This causes a metal-to-metal contact, resulting in a clicking sound. When the engine accelerates up, this repetitive knock usually becomes louder. The temperature of the engine will not vary as a result of this issue, but the RPM will.


If your car develops this condition, your only option is to have your complete engine repaired or replaced. This is something you should consider because replacing an engine is highly expensive; it could cost more than the car's market worth. You should chat to your mechanic about whether you should replace your engine or buy a new car.


  • Worn out Lifters


The valves are opened and closed by a series of lifters in the engine's cylinder head. And these lifters could wear out and result in a metal-on-metal ticking noise at idle and during acceleration. Regular oil changes should help to dampen the noise, but you may need to have the lifters changed by a mechanic.


  • Bearings or fittings that are defective


Engine clicking can be caused by a faulty bearing or other component in some cases. Bearings degenerate over time, causing wobbling or spacing, which results in the clicking sound. The sound you'll hear will depend on how much the component is destroyed.


You must figure out what is causing the engine to click. You can do this by starting your car and using an automotive stethoscope to listen for the source of the clicking sounds. Keep in mind that you should be extra cautious when using this tool. You must keep it, as well as any other items of clothing, jewelry, or hair, away from any moving parts of the vehicle.


Do not use the automotive stethoscope to test the noise if it appears to be coming from the front. To check whether the clicking sound has stopped, just remove the belt and run the engine for 30 seconds to a minute. Then turn off the engine and let it cool before inspecting each component.


  • Engine fan loose parts


The engine is equipped with a fan that might make a clicking or ticking noise if it is damaged. It's also possible that any loose parts are rattling about, causing the noise.


Examine the fan's blades and shrouds for any signs of damage. Check for any loose parts, such as the nuts or clips that hold the radiator shroud in place. Heat and dust shields, brackets, metal lines, and any other components that may vibrate and come into touch with other components should all be thoroughly examined.




If you haven't changed your spark plugs in a long time, then your engine may be clicking because of that. If your vehicle isn't that old or you haven't replaced your spark plugs yet, the clicking sound could be caused by a spark plug that isn't installed properly, causing exhaust gas bypass and engine click. When performing a do-it-yourself tune-up, this problem is common.


Visually inspect your spark plugs to fix this issue. When you do this, make sure your engine has cooled down and is turned off. Wiggle the plug and remove the spark plug wire. When it moves, you'll know it's loose. When it becomes loose, pull it out and check the thread. Reinstall it if there is no damage, and check sure the spark plug is torqued properly. When tightening it, make sure you follow the manufacturer's instructions.


Replace asap if you see signs of damage or cracks. If you notice that it has stripped the cylinder head’s threads upon inspection, you will have to remove the cylinder head to repair or replace it. Unlike replacing the spark plug, removing the cylinder head should be done by a mechanic.


  • Exhaust leak


A loud engine can be caused by any leak in your exhaust system. A clicking noise might be caused by a leak in the exhaust manifold. A blown head gasket, fractured manifold bolts or studs, or a damaged manifold can all cause a leaking exhaust manifold. If the clicking sound is accompanied by an exhaust odor, you may have a leak.


You can rev your car's engine while it's in park to see whether it has an exhaust leak. You should be able to get it to around 2,500 rpm. If the clicking sounds goes away after you do this, you most likely have an exhaust leak. If the noise persists, it's possible that the issue is with the oil pressure.


Can engine clicking be fixed? The work that has to be done is time-consuming and can be costly. To find out how much the repair will cost, speak with a mechanic. If the repair expense exceeds the market worth of your car, it is preferable to go on and sell your car as is.


  • Valves that have been misadjusted


Engine clicking could be caused by misaligned valves. This is possible because these valves open and close multiple times as the engine spins. A rocker arm is also included, which is responsible for opening and closing the valves. It is regulated by a camshaft with a pushrod that must be perfectly aligned with the valve.


Because these valves move too quickly and over such a limited space and time, it needs to be that way. If the adjustments are not correct or precise, components may move about, resulting in clicking noises. Have it checked by a mechanic and the valves adjusted.


  • Engine clicking may be caused by worn-out driving pulleys.


Finally, if none of the other possible causes appear to be the issue, the engine's drive pulleys should be examined. These pulleys need bearings to spin, similar to the wheels on a skateboard, and the bearings tend to wear out over time.


Can engine clicking be fixed? The pulleys can make an unpleasant ticking noise at idle and under acceleration when they wear out. If the bearings on the pulleys are worn out, we recommend sending your automobile to a certified mechanic to get them replaced.

Why is my engine ticking when I accelerate?


Oil pressure, exhaust leaks, spark plugs, or the valvetrain are the most common causes. All of these issues develop when the engine RPMs grow, as the sounds get amplified. It won't cost you much to fix these problems, but make sure you discover what's wrong as soon as possible.


Can a transmission make a ticking noise?


A transmission does not normally create a clicking sound. When a car is in gear and you hear a clicking sound that gets louder as the vehicle speeds up, it's usually an axle, differential component, or even a belt or pulley. If the noise is more like grinding, the issue could be as simple as a faulty synchronizer or a transmission fluid and filter that has to be cleansed and replaced. It's a good idea to have a professional mechanic come to your site and perform a noise check so that the problem may be properly isolated and diagnosed.



Can engine clicking be fixed? Engine clicking noises are fairly common, and depending on the reason, they can be either very terrible news or not particularly serious. They can even be entirely normal and to be expected in specific circumstances. Whatever the reason is, take comfort in the fact that engine clicking most likely can be fixed.
