The engine cylinder is replaced or repaired

1. If the engine has a cylinder pulling phenomenon, the cost after micro-repair is not high, if it is not If it is recommended to replace the engine, the repair cost will become very high. Just fix it directly. For the problem of the engine cylinder, it is best to replace it with a brand-new cylinder.

2. If the phenomenon of pulling the cylinder really occurs, it is recommended to replace the cylinder and piston. However, there are very few repair shops with bowling bats now. Please try to repair them.

3. In fact, the handling of engine failure depends on its size. If the engine is too bad to repair, replacing a new engine is the best choice.However, sometimes replacing a new engine is neither practical nor cost-effective, because the overall performance of the new engine may not be comparable to that of the original engine.

What's wrong with the new engine pulling the cylinder?

1. The piston ring in the engine is stuck or broken, and the deformation of the piston pin is the main reason for the engine to pull the cylinder. The engine noise is abnormal, the oil pressure is too low, and the oil channel is blocked, which will cause serious exhaust under the engine, and the pressure in the engine crankcase will increase, which will cause an explosion in the engine crankcase when it is serious.

2. Reason 3: The engine runs at high speed. When the engine is running at high speed, especially under empty load, the most common consequence is that the vehicle engine explodes, which causes the problem of pulling the cylinder of the engine.

3. The main reasons for the engine to pull the cylinder are: improper assembly during overhaul causes the cylinder to pull.

4. The cylinder is caused by different degrees of adhesive wear under lubrication conditions. When the cylinder is light, the cylinder liner and piston assembly will be damaged; if it is serious, it will cause a malignant machine damage accident that bites the cylinder. How to prevent the engine from pulling the cylinder? Pay attention to the engine water temperature when driving. The normal water temperature is 70℃~95℃ to avoid overheating of the engine.

5. There are many reasons why the engine pulls the cylinder, including the following four reasons. Let's take a look! Reason 1: It is well known that there is no hot car on the road in winter, and the temperature is low in winter. When the owner drives on the road, he should do a short preheating operation on the vehicle to reduce the damage to the engine cylinder.

The middle cylinder assembly of the car engine has been replaced. How many kilometers does it need to be maintained?

1. The third time can be maintained as usual, but it's better not to exceed 7,000 kilometers. Change the oil in time to protect the engine, so that the power of the engine will also be very good.

2. Hello, normal maintenance can still be used for 100,000 kilometers. I hope my answer can help you. I wish you a happy use of the car [If you have any questions about the car, ask the car master. 4S store professional technician, 10 minutes to solve.

3. The car engine needs to be maintained once in half a year or more than 5,000 kilometers. Generally speaking, the engine maintenance of the car needs to reach a journey of more than 5,000 kilometers or half a year before it needs to be maintained once.

4. So for the turbocharged engineBicycles are recommended to maintain within 5,000 to 7,000 kilometers, and for naturally aspirated engines, it is recommended to maintain within thousands to 10,000 kilometers.

5. The first maintenance of a car is generally when the mileage is 3,000 kilometers to 5,000 kilometers after the new car is bought. Specifically, it should be maintained according to the car manual. The first maintenance of the new car is relatively important. If you miss the opportunity, it is likely that the national joint warranty system will not have the owner's information, and then it will be out of warranty.

6. For this car, it's not a big problem to replace the middle cylinder and run over 200,000 kilometers. I hope my answer can help you. If you don't understand anything, you can continue to ask me! I wish you a happy life! [ If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

Changing the middle cylinder is equivalent to changing a new engine

This statement is incorrect. A complete engine should include sensors and control systems, and the engine also includes crank connecting rod mechanism, cylinder head, gas distribution mechanism, fuel supply system, etc. Therefore, replacing the middle cylinder does not mean replacing a new engine.

So changing a medium cylinder is not the same as changing a new engine.The engine is not a whole. The engine consists of a valve chamber cover, a cylinder head, a cylinder block and an oil sup from top to bottom. The cylinder in the middle is the cylinder block, which will wear out as the mileage increases. If the wear is serious, it needs to be replaced.

This statement is not good. A complete engine should include sensors and adjustment systems. The engine also has crank connecting rod mechanism, cylinder head, gas distribution mechanism, fuel supply system, etc. Of course, changing a middle cylinder is not the same as changing a new engine. The engine is not a whole.
