How to tell the difference between the engine and the mattress are flushed? Or is the pump pad flush

Pull out the dipstick to see if there is a watermark, or take the trouble to pick the engine head to see if the cylinder mattress is bad...1. String gas, high-pressure and high-temperature gas will be stringed out of the cylinder gasket, the engine power will drop, turn off or cannot be high-speed and fully loaded.

2. Oil leakage, there will be lubricating oil leakage from the cylinder gasket, and the oil pan oil consumption is large, causing the engine to burn the crankshaft.

Wait. 3. If there is water leakage, there will be cooling water.

Leakage from the cylinder gasket and high water consumption will cause the engine to dry burn, cylinder deformation, etc.

4. Water leaks into the oil pan, the water consumption is large, and the oil emulsifies, causing the deformation of the crankshaft and the engine dry-burning cylinder.

5. The gas enters the oil pan, causing the respirator to string gas and causing the engine cam.

Poor lubrication of rocker arms and other parts reduces engine power.

6. The gas enters the waterway, resulting in the water tank stringing, the engine power decreases, the cooling is not good, and the cylinder is deformed.

Reasons:1When installing the cylinder head, the bolts of the cylinder head are not tightened in the required order or the bolt tightening torque is insufficient, which causes the cylinder gasket to be damaged when the engine is working.

2.The diesel engine has been working under the condition of premature fuel supply for a long time, which makes the pressure rise rate of the rapid combustion period during combustion too large, exceeding the allowable value, resulting in the cylinder head gasket being damaged.

3.The deformation of the cylinder head and the size of the cylinder liner above the upper plane of the body are too large, and the cylinder head has the phenomenon that the cylinder head is not compacted during installation, so that the cylinder gasket is washed out.

4.Poor manufacturing quality of the head gasket or deformation of the head gasket and uneven and notched cylinder liner stops can also lead to the head gasket flushing.

Walk through the high temperature, and then check the cylinder head, whether there are cracks on the body, if not, just change the cylinder gasket

Answer: The cylinder gasket will be flushed, the water will enter the oil, it will not lead to the burning of the oil, it will lead to the emulsification of the oil, pull out the oil ruler will see the oil whitish, and the cylinder gasket will be no problem if you change it.

You can give a thumbs up for your hard work.

Have a great day.

Ask what is the cause of burning engine oil.

Clause. 1. Aging of valve oil seals.

If the vehicle starts in the morning, there is blue smoke from the exhaust pipe, and the blue smoke disappears after a period of time, it means that the engine oil is burned when the engine is started, and this situation is most likely due to the broken valve oil seal. The valve oil seal is a component installed on the valve guide rod, and its function is mainly three: one is to seal the intake and exhaust valves to prevent the oil or exhaust gas in the cylinder from leaking from the intake and exhaust valves, the second is to prevent the oil from entering the cylinder, and the third is to prevent the oil from entering the intake and exhaust pipes.

If the valve oil seal is broken, the oil will seep into the cylinder along the valve guide rod and mix with the fuel to burn, and the engine will emit blue smoke. The valve oil seal is a rubber part, which will deteriorate after a long period of use, affecting its tightness. In addition, if there is a problem with the oil seal of the vehicle with a small number of kilometers, it is most likely that the oil seal structure is damaged during installation, or foreign matter enters, resulting in damage to the seal and causing the oil to enter the combustion chamber.

Clause. Second, the exhaust valve is damaged and aging.

When the engine is running, the high-temperature and high-pressure gas in the cylinder will be drilled into the crankcase from the tiny gap between the piston and the cylinder block, and the oil in the crankcase will also produce some oil vapor due to the high temperature, and the exhaust valve is to screen these mixtures, leave the usable oil in the crankcase to continue to use, and discharge the "undigested" exhaust gas to the intake manifold, and then enter the cylinder for secondary combustion.

If the exhaust valve fails, it is impossible to separate the oil from the crankcase mixture, which transfers the oil vapor and fuel mixture to the intake manifold and then into the cylinder for combustion. In this way, the wastegate is equivalent to losing the ability to "screen", and to exaggerate, it is equivalent to connecting the pipe from the crankcase to the intake manifold, which will not only cause a serious waste of oil, but also increase the carbon deposit of the engine and make the power worse.

Clause. 3. The accessories in the cylinder are damaged.

If you find that the vehicle emits blue smoke when accelerating, it is likely that the piston rings in the cylinder are worn and the engine oil is burned. Due to the increase of carbon deposition in the cylinder, the oil seal ring and air seal ring of the piston will be wrapped in carbon deposition, losing the original sealing function, and the cylinder block will also be scratched by carbon deposition, and the overall airtightness will be greatly reduced. Compared with the above two cases, in the case of damage to the accessories in the cylinder, the maintenance is the most troublesome, and the engine needs to be dismantled.

The accessories in the cylinder lose their sealing effect, and the oil in the crankcase will flow into the cylinder through the gap between the cylinder block and the piston, and burn together with the fuel, and the high-temperature and high-pressure gas inside the cylinder will also flow to the crankcase, and finally lead to the decline of the vehicle's dynamic performance. In addition, the usual use of inferior engine oil will also cause accelerated wear and tear of the cylinder block, so be sure to choose the best engine oil.

Ask what is the cause of the blue smoke emitted from the cart.

First of all, you have to understand the role of the head gasket, which is used to seal the water jacket and the cylinder liner. If the cylinder gasket is flushed, it will cause the water jacket and the cylinder liner to be unsealed, and the water in the water jacket will enter the cylinder liner, and the gas in the cylinder liner will also enter the water jacket. On the one hand, the water will decrease, and on the other hand, the temperature of the gas inside the cylinder liner is very high, and when the gas enters the water jacket, the water temperature will increase.

Because of this, when the head gasket is flushed and the tank lid is opened, a large number of bubbles will come out.

The so-called punch, punching, is breakdown. The seal is not good, the oil leaks, the water leaks, and the air leaks. There are three or four situations.

Second, the water circulation system and oil circulation system were flushed. If the oil and water are flushed, there is water in the oil, organic oil in the water, the oil emulsifies semi-solid, and the water tank is seriously blocked. The third is that the water and exhaust tract are eaten, and the white smoke is full.

From time to time, there is a shortage of water. There is a fourth rare phenomenon that is not obvious, that is, the gas and oil channels are charged, if the machine is running at high speed and the load is heavy, the engine outlet may be injected with fuel.

The impact of the engine cylinder mattress flushing is: 1. The cylinder and cylinder head cannot be sealed, and the cooling water will enter the cylinder, resulting in cylinder failure; 2. The cylinder is full of water, and it becomes water vapor at high temperature, and the cylinder will be seriously rusted; 3. The cooling water will often lack water due to excessive consumption, and the cooling water can be seen in the auxiliary tank where the water is added can be seen to become turbid and boiling and bubbling. The workaround is:

Replace the engine cylinder mattress. Hail engine cylinder mattress is referred to as cylinder gasket, which is an elastic sealing element placed between the cylinder block and the cylinder head. Since it is impossible to be absolutely flat between the cylinder block and the cylinder head, it is necessary to have a cylinder head gasket to prevent the high-pressure gas reed substrate, lubricating oil and cooling water from escaping from between the cylinder block and the cylinder head.

Reasons for engine flushing of the cylinder gasket: 1. The quality of the cylinder gasket is too poor. In the production process of the cylinder gasket, the material from which the cylinder gasket is made does not meet the quality requirements.

The asbestos material contained in the cylinder gasket and the side distribution are uneven, the shape, position and size accuracy of each hole are not enough, the cylinder gasket is damaged during installation, and the weak part of the cylinder gasket will be broken down under high temperature and high pressure; 2. The cylinder head is deformed. Due to the defects in the cylinder head in the state shed during the manufacturing process, the cylinder head was deformed in use, so that the cylinder head gasket could not be tightly compressed. When the engine is working, the high-pressure gas rushes out of the micropores, which breaks the cylinder head gasket; 3. The cylinder head is not properly assembled.

When assembling the cylinder book shed, the tightening torque of the nut is too small, the nuts are not uniformly tightened in the order of the diagonal, or the tightening torque of the cylinder head nut is too large to cause the bolt to be deformed, so that the cylinder gasket can not be tightly pressed between the cylinder head and the cylinder body, and when the engine is working, the high-temperature and high-pressure gas rushes out of the cylinder, and the cylinder gasket is broken; 4. The bolts of the cylinder head are loose. Due to the loosening of the bolts of the cylinder head, the pressure on the joint surface of the cylinder head and the cylinder gasket is inconsistent, and gaps appear in some parts. When the engine is working, high-temperature and high-pressure gas escapes from the gap, which washes out the cylinder gasket.
