What is the reason for the sound in the safe after the Cruze oil change

Why does there be a sound of dust limbs after changing the engine oil? The engine makes a noise after changing the oil, mainly from the position of the valves. Here's why:

The viscosity of the oil is too thick or too thin: If the viscosity of the oil is too thick, it will directly affect the normal working condition of the hydraulic tappet (the resistance to be overcome is greater), so that the oil rises slowly, so the valve sounds. Oil products for engine oils:

Poor quality oil performs poorly, resulting in poor valve lubrication, so when the engine starts, the valves make abnormal noises. Driving in the cold: If the car is driving in the cold, the engine will make a "click" sound.

This is because the car has been parked for a long time, the oil pressure has not gone up, and the valves have not been lubricated. If the sound is loud all the time, it may be that the valve clearance is too large or the camshaft is leaking. It is necessary to adjust the valve clearance or replace the relevant oil seals.

Summary. If this sound occurs after changing the oil, if this needs to be treated, it is necessary to change the oil with a relatively high viscosity. The main thing is that the oil is relatively clean after changing the new engine oil, and the viscosity of the engine oil is relatively low, so it is said.

Therefore, there will be this kind of sound after the engine starts, which has nothing to do with it, as long as the engine power is normal, and there is no fault light, then there is no effect, and it can be used normally. If it needs to be treated, then it is necessary to change the oil with a higher viscosity. However, changing the oil with a high viscosity will lead to an increase in the engine's fuel consumption.

If this is the case, how to deal with it.

If this sound occurs after changing the oil, if this needs to be treated, it is necessary to change the oil with a relatively high viscosity. The main reason is that the oil is relatively clean after replacing the new machine sock oil, and the viscosity of the oil is relatively low, so it is said. Therefore, after the engine starts, there will be this kind of sound that acre is excited, which has nothing to do with the fierce Zen, as long as the engine power is normal, there is no fault light, then there is no impact, normal use can be.

If it needs to be treated, then it is necessary to change the oil with a higher viscosity. However, changing the oil with a high viscosity will lead to an increase in the engine's fuel consumption.

See. Is it better to add 5w-30 or 5w-40 to my car

With 5w-30's.

There is a clattering sound, is there any damage to the engine?Do I need to change the oil again?

This early balance does not have any branch sail effect, normal use can be, the engine is hail will have this sound, some engines are more obvious, some engines this sound is relatively small, idle will appear.

I changed the oil again, the Castrol oil is 5w-40 and the engine is still clatter.

The engine itself will have this sound of high speed, and every engine in the middle will have idle speed, and there will be a sound of selling stupidity, which is a normal phenomenon.

The squeak of the car engine after changing the oil is the key to the part of the cylinder. So, what to do about the sound of the vehicle valve, today I will give you an in-depth analysis.

The abnormal sound coming from the car valve is probably due to the oil viscosity being too thick or too thin. If the oil viscosity is too thick, it will undoubtedly jeopardize the normal operation of the hydraulic press (the frictional resistance that must be solved is higher), so that the oil cannot keep up, so the valve rings are not taken seriously.

If the oil viscosity is too thin, of course, it will not bring a good smooth practical effect, and in the long run, the car engine will be obviously damaged, and the oil working pressure will be reduced by the original Hui Zen cause, resulting in the situation of valve sound. Therefore, when you fill the engine oil, you must pay attention to whether the viscosity of the engine oil is suitable for your car.

Naturally, the refined oil with the engine oil also has a certain impact, and the fake and inferior engine oil usually does not have very good special dust content, so that the cylinder has a thorough moisturizing time, so when the car engine starts, the cylinder will come out with a "click" abnormal sound. Therefore, everyone must buy engine oil in a reliable way to prevent falling into the trap of black businessmen again.

Millions of car purchase subsidies.

If you obviously feel that the engine noise becomes louder after changing the oil, there are the following reasons: 1. The engine oil does not meet the standard or the amount added is too much.

2. At the end of the run-in period of the new car, the engine sound will be improved and the fuel consumption will decrease.

3. The viscosity of the new engine oil is high, the mechanical resistance is large, the pressure in the cylinder will also increase, and there will be a cooing sound.

Because the first guarantee is the worst mineral engine oil, the power of 3000 kilometers is almost attenuated. I usually use GT Magic Red at high speed, and the power is also stable from 100 yards up, and the engine sound is not abnormal. The gap between mineral engine oil and good engine oil is still relatively large, if there is a condition to replace it now, its practical use of engine oil will be more affordable, I now run more than 10,000 kilometers and then change it to a lot longer, it is best to go to the maintenance shop to change, you can bring your own oil filter labor time cost is also a lot less.

If there is black powder on the surface, there is a sense of astringency when touched by hand, you can clearly see that there is no abrasive debris in the lubricating oil, which can continue to work, if the abrasive debris is excessive, the lubricating oil should be replaced without friction.

2. Illumination method. Compare with the sun, check the oil droplets, under the light, after the lubricating oil leaks.

Oil Selection Method:

1. Hand twisting method: twist the lubricating oil between the thumb and index finger and grind it repeatedly, and a few drops of oil will have an impact on the filter test paper.

Adding too much oil will increase viscosity: take a clean white filter test paper, less abrasive debris, if you sense a large friction sensation such as sand between fingers, the engine efficiency will decrease, and the phenomenon of burning engine oil may occur. If it is only more than a little bit, at an angle of 45 degrees with the degree surface, and the better lubricating oil hand induction has lubrication, it is explained that there are many impurities in the lubricating oil, and it is not too late to use it again.

If it's too much, it's best to pull off a little.

3. The new lubricating oil should be replaced, which means that there are many impurities in the lubricating oil: on a sunny day, use a screwdriver to pick up the lubricating oil, and the good lubricating oil has no powder, and it is dry and smooth to the touch, and it is yellow.

There are many reasons for the noise after changing the oil: 1. The quality of the engine oil (true and false; fully synthetic, semi-synthetic, mineral oil; And so on).

2. Different brands and different grades of engine oil (0w-40, 0w-30, 15w40.......

3. The same brand and the same grade, due to the change of the fluidity of the new oil and the old oil. "The best time for high-quality engine oil is 7500 minutes.

1. The engine has abnormal noise.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is abnormal sound of wear.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door. In terms of brand selection, try to choose the commonly used brands in 4S stores, such as German Marty, Kluber, Tiger Head Hotolube, Fox, etc.

It is not advisable to use engine oil or ordinary butter, it will freeze in winter, and the harmful smell will affect your health.

What is the sound? Chevrolet 4S shop repair technicians answer for you.

1. The oil pressure sensor is broken.

2. The oil pump is not working.

3. The oil pipeline is blocked.

4. Failure of oil circuit pressure relief valve and other faults.

5.The simple way is to open the Verr shell and see if there is organic oil coming up on the camshaft, if the organic oil comes up, it proves that the oil pump and lubrication line are working properly, maybe the sensor is broken. If there is no oil on the camshaft, it may be that the oil pump is not working, the pressure relief valve is leaking, etc.

Whether the oil is enough or not, whether the filter is blocked or not.
