Blown head seals can be very bad news. It either costs money when it's fixed, or you have to do the work yourself. Both methods cost money, but this can save you money. But before you can fix it, you need to know the reason. This can be a problem as there may be several reasons for the blow-seal.


1.
Installation error

If you replaced a blown head gasket in your vehicle and solved the problem of why it even jumped, it's probably because of an
installation error. This is not unusual.
The cap screws must be tightened in the correct order and adjusted to the appropriate torque. You must also have clean threads that are not stretched or damaged. The surfaces of the cylinder head and the engine block must also be smooth, clean and flat.

Each of these factors, or a combination of these, can cause blowing of the cylinder head gasket. Remember also that Sealer should only be used with unpainted, one-piece steel seals. However, it can be difficult to determine the cause. You must first exclude other options.

2.
Overheating

Overheating is the main cause of blowing a cylinder head gasket. Normally, the cylinder head gasket around the cylinders may be damaged. When this occurs, the seal is lost and the engine loses its compression, the coolant escapes and the seal erodes.

Before replacing the seal, you must find the cause of the overheating. This may be due to coolant leaks in the engine, hoses, radiator or water pump. These must be found and repaired. It may also be because the radiator fan is not working or the radiator is clogged. These too must be repaired, otherwise you will get a molten gasket shortly after your repair.

3.
Hot spots

Between the middle cylinders of the cylinder head, there are engines that are exposed to hot spots, although the cylinder head gaskets for these engines are subsequently reinforced to reduce the risk of the cylinder head.

However, if you have an older car, the hot spot may be the cause, especially if your old gasket has been replaced with a non-reinforced gasket.

4.
Problems with inflammation

Ignition problems can also cause this problem, especially if you only use your car for city driving. At pre-ignition, there is a hot spot in the chamber that causes ignition of the fuel before the spark plug ignites. This could also be due to the detonation. This happens when the ignition timing is too advanced or the fuel mixture is not rich enough. This leads to an accumulation of carbon deposits and erodes and destroys the space.

5.
Bad head gasket

In some cases, the original car head gasket may be poorly designed and its poor design may cause the head gasket to blow over time. A little research will determine if your vehicle is prone to bad constructions. If you have replaced it with a good head gasket, you should not notice other failures.

Notable Points

If a region of a car is faulty it will surely disrupt other operations, a blown head gasket should not be permitted in a vehicle.
