When I went to do the maintenance of the car, the mechanic told me that the engine was leaking, how

1. Oil pan gasket leakage.

If the oil pan leaks, the engine will only have oil underneath, which can be observed with a flashlight, some oil pans are easier to disassemble, you can buy accessories online to replace, remember to apply the sealant evenly, and the bolts should not be too forceful, otherwise it is easy to break. For oil pans that are not easy to disassemble, it is recommended to go to a repair shop for replacement. In addition, if the oil drain bolt pad is leaking, it can be done by adding a mat by yourself.

2. Engine oil leakage and engine oil leakage are two different concepts.

Engine oil leakage.

The phenomenon of oil leakage is not easy to be found by the car owner, generally when the owner goes to the 4S shop to maintain the car, the maintenance technician will explain the situation of the car when **. In fact, every time the owner goes to wash the car, open the front hood to simply check the condition of the engine, if there is thick sludge in which part of the engine, it means that this place is leaking oil, and the specific maintenance needs to see the oil leakage.

Engine oil leakage.

If you wake up one morning and drive and find a puddle of black liquid under the car, and the smell is very choking, you can tell that it is an engine oil leak (other systems may also be).

3. Treatment method.

Oil leakage from the valve chamber cover. Cars that have been used for about 5 years are more common, and the valve cover gasket needs to be replaced.

Oil leaking from the engine timing cover. Remove the engine timing cover and re-glue it.

The oil pan drain screw is loose or damaged. Tighten or replace the drain screws.

The main reasons for the phenomenon that the car cannot be turned on, and the engine of the cold and hot car cannot be started are as follows:

1. The battery voltage of the car is low; Specific detection method: test the battery voltage with a three-purpose meter voltage level, if it is below 10V, it is recommended to replace it. If it is around 11V, it is barely used; Be prepared for replacement. Above 12v can be used, but other reasons need to be found;

2. Check whether it is caused by carbon deposits; If you travel about 20,000 km, focus on checking and cleaning the throttle;

3. Inspect, test and replace spark plugs;

4. Confirm the quality of the gasoline added;

5. Detecting the ignition switch;

6. Test and detect the starter, gasoline pump, sensor and other related components of the starting and oil supply system;

7. After powering on, do not start immediately, wait for 30 seconds to 1 minute, and then ignite; See if it works;

Regardless of any of the above situations, pay attention to the time when the car cannot be hit once, be sure to play again after an interval of 15-30 seconds to protect the battery but not generate power and prolong its service life.

Engine oil leakage, complex.

According to the actual situation in the past, the system is mainly focused on the following aspects:

1.The upper and lower block head gaskets burned through the string gas, resulting in lubricating oil leaking out (in the upper middle of the engine);

2.The local insufficiency of the adhesive at the junction between the lower cylinder block and the low cylinder block leads to the existence of gaps and oil leakage;

3.The uneven gluing between the oil pan and the engine block leads to weak spots, which crack and leak oil after long-term consumption;

4.Cylinder block, oil pan trachoma, cracking.

It is recommended to talk about the vehicle rising, wipe the oil stains attached to the engine, and then heat up the engine or directly cool the engine to observe, see the oil stains seep out from the **, and you can find the reason.

The reason for gluing is very easy to deal with, after dismantling, re-glue and then put it on, but be sure to scrape the original glue clean.

The cylinder head gasket is directly replaced if it is burned out.

If the oil pan, cylinder block and head cracks, and sand holes are abnormal, you should directly negotiate with the manager of the 4S shop to replace the engine, otherwise you will directly inform him and complain directly to the General Administration of Quality Supervision, Inspection and Quarantine if you do not deal with it (the main engine factory is very afraid, and the 4S store is under great pressure from the main engine factory).

There is no clarity to give me information directly.

1.More than 90% of the causes of engine oil leakage are caused by the aging of seals (oil seals)! Seals (oil seals) harden over time, i.e. they lose their plasticizer over time.

This process is exacerbated by the constant alternating operating temperatures of warm and cold. As a result of this poor process, the seals first begin to shrink, then harden, and finally even break, and oil leaks are inevitable.

2.The traditional maintenance plan is to dismantle and repair the vehicle, and the man-hour cost is often thousands of yuan, as well as the cost of replacement, and the maintenance time is long. At the same time, due to improper operation and other reasons in the process of dismantling and repairing, the vehicle has many other sequelae.

Some oil leaks need to disassemble the engine, so I advise you not to disassemble it easily, the car is not broken, it is repaired! Traditional solutions can be summarized as time-consuming, labor-intensive, and costly.

3.Now the more popular oil leakage solution is to add German Mattie DS directly to the oil, under normal driving, the oil leakage problem will disappear naturally in about 14 days, and the car will not be delayed for dismantling and repairing, so as to avoid the waste of time and money caused by dismantling and repair, and it is easier for the owner to solve the oil leakage problem by himself.

4.It is recommended that 3-5 year old cars be added to Marty DS in advance to prevent oil leakage.

The original bai of the oil spill

Cause: its solidity, more than 90%.

The oil leakage problems are caused by the aging of the sealing parts!

Seals harden over time, which means they lose their plasticizer over time. This process is exacerbated by continuous, alternating hot and cold operating temperatures. As a result of this poor process, the seals first begin to shrink, then harden, and finally even break, and an oil leak inevitably occurs.

According to statistics, more than 90% of automobiles, especially those with a service life of more than 5 years, are due to the lack of good maintenance for long-term use, resulting in the wear and aging of seals such as oil seals, and the lack of strict sealing, resulting in leakage of oil, gear oil, hydraulic oil and other poorly sealed gaps, resulting in oil leakage from engines, gearboxes, steering machines, etc.

By directly joining Marty DS, through the contact with seals such as oil seals, Marty DS will get back those softener plasticizers that have been lost in the past, and the old oil seals and other seals will become flexible again, and at the same time, can withstand higher temperatures and pressures. Under the influence of Marty DS, seals such as oil seals can easily expand, and the tightness can be restored in 14 days. No need to disassemble, say goodbye to oil leakage completely! Check it out:

Changan van.

Prone to oil leakage. Especially the valve chamber.

Cover crankshaft rear oil seal.

And the oil bottom. When you encounter such a thing, go to the 4S store and dispose of the oil leakage.

within the shelf life.

There is no charge.

1. The quality, material or process of the product (accessories) is poor, and there are problems in the structural design. 2. Improper assembly, unclear surface of parts and components, damaged gasket, displacement or installation not in accordance with operating procedures. 3. The work failure is caused by uneven tightening force of the fastening nut, broken sliding wire or loose falling off.

4. After long-term use, the sealing material is overworn, aging, deteriorating, deformation and failure. 5. Add too much lubricating oil, the oil level is too high or add the wrong fuel. 6. The joint surface of parts (side covers, thin-walled parts) is deflected and deformed, and the shell is damaged, so that the lubricating oil seeps out.

7. After the breather plug and check valve are blocked, due to the effect of the air pressure difference between the inside and outside of the box, it will often cause oil leakage in the weak part of the seal.

Car engines.

There are two basic scenarios for the cause of an oil spill:

1. Oil leakage from automobile engine. There are relatively clear oil stains on the surface of the car engine shell, if the oil stains are cleaned up at this time, and the oil stains on the shell are found soon after, and even some serious gasoline is still falling like water droplets, this problem should be sent to the car for maintenance as soon as possible.

2. Oil leakage from automobile engines. There is only a small amount of oil stains in the engine shell, which means that the engine oil leakage is not particularly serious, and the oil leakage at this time is not obvious and small, and it has little impact on the engine at this time.

The most direct and effective way is to put the sealing ring.

The working pressure inside is greater and the temperature is higher, which accelerates the aging and deformation of the rubber at the transmission seal.

There is also a small part of it because the transmission oil is added too much, which increases the resistance of the transmission gears. When the gears of the transmission are strained, problems in the case will also increase, resulting in oil seals.

Sudden large-scale oil leakage, such as yesterday was fine, today suddenly found that there is a large pool of oil on the ground, often caused by the oil pan bottom deformation, rupture or the filter is not tightened. When such a problem occurs, you should immediately check the oil balance and go to the repair shop to check it as soon as possible.

Extended Information: Causes of Engine Oil Leaks:

1. Engine oil leakage caused by poor sealing of valve chamber cover gasket, oil radiator, oil filter, distributor housing bearing hole, rocker arm chamber cover, cam bearing rear cover and engine bracket plate deformation.

2. The crankshaft of the car.

The front and rear oil seals and oil pan gaskets are damaged to varying degrees, which can also lead to engine oil leakage.

3. If the timing gear cover gasket of the car is not properly operated during installation, or if it is damaged to a certain extent, the screws are loose and leaking.

Handling of engine oil leaks and hazards:

1. The solutions taken for different models are also different, some engine oil leaks do not need to remove the cylinder block, but some parts of the oil leakage cylinder block need to be removed. It is best to deal with it according to the specific situation of the car.

2. The engine oil leakage of the car is not a big fault, and we do not need to repair the car for the time being.

However, if there is an oil leak in the engine, it needs to be carefully inspected.

3. The engine oil leakage of the car will bring certain damage, the most important of which is to cause the car to lose a lot of oil, and there is a waste of it. If it is severe, it may cause damage to the engine due to insufficient oil.

Hello, yes, you can replace the seal. If I can help you, please set it to, thank you! I wish you a safe journey and a safe journey.

Full-time all-wheel drive, boxer-opposed engine. It's Subaru's unique technology, so his series are all like this. The boxer engine provides a balanced distribution of power, and with full-time all-wheel drive, it is much more stable than other front- or rear-wheel drive vehicles.

Oil leakage from a car engine is a very dangerous problem because if you don't deal with it, you can get into a traffic accident while driving. My personal opinion is that I should go to the nearest car repair shop to fix the oil leak, or replace such a device directly, so that it can have a good protection effect on myself and the car. Nowadays, everyone's life is getting richer and richer, almost every household has a car, and everyone's use of cars is becoming more and more frequent, and many people drive to work and travel, etc.

But as a tool that is often used, the car is also prone to problems, and the engine is a place where problems can easily occur. Generally speaking, the engine is the power unit of the entire car, so if something goes wrong, it can stop the car from walking. If it is an oil leak then it is more serious because the oil leak may cause the car to have no money on the side of the road before.

On the question of what to do if there is an oil leak in a car engine, let me give you my opinion.

First, first check whether the pipe is not connected properly.

Generally speaking, there are many problems with engine oil leakage, and sometimes if a leather pipe is not plugged in, it can also make the car engine leak, because the transmission between the fuel tank and the engine is transmitted through the oil pipe. When the car is turned on, there will be a lot of vibration, so sometimes the oil pipe will break free, which will cause the car engine to leak, in this case, you can deal with it yourself.

Second, if it is a problem with the pipe or engine, you should go to the nearest repair shop to replace it.

If the car oil pipe itself is cracked, or the engine has a problem, then you may not be able to deal with it, so you have to go to the nearest repair shop to replace, generally speaking, the car repair shop is very experienced in this kind of car problems, you can immediately check it out and deal with it for you.

3. Once the engine oil leakage problem is found, then try to stop driving.

When we drive a car in our lives, once we find that the engine is leaking, we must be determined to stop driving, because these oils are generally flammable substances, and if you encounter some sparks, it is very dangerous, so for your own safety, try to repair it before driving.

Because the engine is an overall structure, we must first see what position is leaking, if the cylinder head, screw gasket is simple, directly replaced, and the seal is not good, it is necessary to disassemble the machine and install a new gasket, in addition, the bottom shell, crankshaft oil seal, oil filter, are common leakage points. The engine oil leakage must be repaired, otherwise there will be a lack of oil, and the cylinder will stick to the cylinder.

In general, cars are prone to breakdown after a long journey. However, when there is a problem with the vehicle, there are some signs. If you feel that the vehicle is abnormal, the rider should first be calm, do not panic, choose a suitable parking place, and check the cause of the fault after parking.

Intuitive diagnosis methods are usually adopted, that is, under the condition of not having machine detection, through sight, hand touch, nose smell, ear hearing and other methods to check the working condition of the car itself. For example, according to the oil consumption, gas and liquid leakage, abnormal noise of various parts, as well as the smell and appearance of the car and other phenomena, analysis and judgment, so as to determine the cause of the failure, and then accurately determine the location of the failure.

Use soap and cloth strips to plug leaks.

Tubing breakage: When the tubing is broken, you can find a rubber or plastic pipe that is suitable for the diameter of the tubing. If the socket is not tight enough, the two ends should be tied with iron wire to prevent oil leakage.

Oil leakage from tubing joints:

Cotton yarn can be wound around the lower edge of the horn, and then the tubing nut and the tubing joint can be tightened; Bubble gum or maltose can also be chewed into a paste, coated on the seat of the tubing nut, and sealed after it dries and sets.

Oil and water leakage: According to the size of the sand hole, the fuse of the corresponding specification can be selected, and the hand hammer can be gently smashed into the sand hole to eliminate oil and water leakage.
