Causes and symptoms of cylinder head failure

According to the Saed News website, one of the main parts of the car engine is the cylinder head, and it is located in the upper part of the engine, and the valve and manifolds are on this part. are assembled. If a cylinder head is subjected to heat beyond its tolerance (which depends entirely on the quality of the cylinder head and its ingredients), it is said that the cylinder head is burnt. in fact The same twisting and deformation due to excessive heat is called burning, which usually leads to the replacement of the cylinder head. According to the laws of physics, heat flow usually moves upwards. Because the combustion chamber of the engine (the hottest part of the engine) is located inside the cylinder head, this part must be able to Tolerate a lot of heat while working. If you do not observe the order of tightening the screws and tighten them too much when opening and closing the cylinder head, if the engine is hot, Try to loosen the cylinder head screws, and again, if you press the car all the time, you have to wait for the cylinder head of your car to be bent and practically useless. Also, there are water and oil flow paths in the cylinder head so that the heat can be controlled, and the oil needed for the set of valves and tools that need lubrication can be used. sent to them.

Time is not the main sign, but you should have it. If your car is brand new or 2-3 years old, there is probably no problem with the cylinder head. However, this is certain It is not and you should pay attention to other symptoms.

Since the cylinder head plays a prominent role in the car engine, its failure will have a great impact on the engine's performance. If the cylinder head is damaged, it will cause problems in the ignition cycle and compressed air may escape.

The task of the cooling system and its liquid is to cool the engine and its components, including the cylinder head. As a result, the failure of the cylinder head can cause the coolant to leak. As for oil, it is possible to detect the leakage of this liquid in several ways. The first way is to observe the coolant and its exit. In modern cars, the Check Engine Temperature sign is also a good sign. One of its causes is the coolant leaking from the damaged cylinder head.

The cylinder head contains oil. This oil is used to eliminate friction and reduce heat. For this reason and by using oil leakage observation, you can easily find the existence of breakdown recognize in it. The detection of oil leakage is that if you park the car in a certain place for a while, you will see oil under it. Also in modern cars, the Check Oil sign on the Ampere plate is an aid to detect oil leakage.

This case has the same reason as the above case. The cylinder head closes the space above the cylinder to compress the mixture of air and fuel and for the combustion to take place in the best way. If the cylinder head is damaged, the cylinder will not be pressurized properly, which means improper compression of air and fuel. In this way, the ignition is not done well and the engine performance suffers becomes weak Even in critical cases, combustion may not occur completely. If not properly ignited, even the remaining fuel can cause damage to the engine. For this reason, if you see this problem, it is better to fix it as soon as possible so that it does not cost you more.

When the cylinder head has a major problem, exhaust gases may enter the engine space. In this case, the smoke can be seen coming out from under the hood and the engine compartment. In such a situation, the cylinder head should be replaced quickly. Consider an important point, that if you see any of the above symptoms, don't wait for the smoke to come out of the engine and go to the repair shop and repair the cylinder head if needed.

Note that the prevention of failure and damage in the cylinder head is very important, because in case of failure and the need to repair or replace it, heavy costs will be incurred. The owner will be charged.
