Head gasket burnt, symptoms and information in case of leaks or other anomalies of the radiator. Repair costs and when the cylinder head needs to be redone.
The engine head has the task of sealing and insulating the upper part of the cylinders. We are talking about an important component for the combustion chamber and the cylinder head gaskets can be seen as the weak link of the whole system . They are more prone to wear or damage from high gas temperatures and combustion itself.

Because the cylinder head gasket burns out
Keep in mind that we are talking about a fundamental mechanical component for the combustion chamber. The thermal range of the cylinder head can reach very high temperatures. The average temperature is around 180 ° C but in some areas the temperature reaches 250 ° C. These areas are critical as they generate hot spots and are subject to continuous stress.
The cylinder head gasket burns out due to overheating which can be triggered by several causes.
If the cylinder head cover is closed incorrectly, the gasket is more subject to wear and burns because it is reached by high temperatures.
Again, if a fuse blows and the fan fails to fire at the right time… There are so many cases, so a blown cylinder head gasket is a very common failure.
Head gasket burned, symptoms
How to tell if the cylinder head gasket has burned out? The symptoms to be grasped are many. First of all, if the car consumes a lot of coolant water and you have to constantly top up the radiator coolant, in the absence of leaks, this high demand for coolant could arise precisely from localized overheating in the engine head.
Check under the oil tank cap. When the cylinder head gasket leaks , is damaged or burned, the heat causes a viscous, clear substance to form under the oil plug. If there is this creamy, mayonnaise-like substance under the oil cap, you have a tangible indication that there may be a leak at the cylinder head gasket .
In any case, the absence of this substance under the oil cap does not mean that the cylinder head gasket is intact, so remember to check all the symptoms .
Other obvious symptoms of a burnt head gasket include the classic white smoke from the tailpipe. The white smoke that comes out of the muffler (tailpipe) is caused by the coolant entering the cylinders and being burned along with the air and fuel. As the leak worsens, the smoke becomes whiter and whiter, and you will have to top up the coolant in the water tank faster and faster.
How to prevent the cylinder head gasket from burning
If you have often burned the cylinder head gasket , something is wrong! Are you sure you have carried out all the necessary coupons and checks? To prevent the cylinder head gasket from burning you can follow these simple precautions:
- Frequently check the proper functioning of the fuses
- Check often the state of wear of the electric fan
- When you change your engine oil, inspect it for traces of radiator fluid. A leak at the head gasket allows the coolant to seep through and penetrate to the oil. Since these are two substances with different consistencies, the refrigerant immediately stands out. In this case the damage is already done and the cylinder head gasket already has a leak but, if it is minimal, it is possible to carry out a DIY repair using an adhesive.
Do-it-yourself repair of the cylinder head gasket is only possible in case of slight leaks but not when the entire gasket is damaged. In the event of a leaking gasket, it is possible to seal the leak with special mastics. Sealing mixtures can be a temporary or even permanent solution when the leak is small.
