Damaged or Blown Head Gasket – Causes and Symptoms

If you’ve heard these two concepts in a damaged head gasket or a blown head gasket, there are some things you should know about them. One is what is the head gasket and the other is the causes and symptoms of damaged head gasket.

What can you do to make sure it doesn’t get damaged? And it is important to take such care because replacing the gasket is a big cost. Gasket prices are low, but wages are high. Worse than worrying about such a big expense.

• What is the head gasket?

The cylinder block and the engine head have a metal seal, called a head gasket. This seal has a metal-rubber-alloy cover. These wraps are made of 1mm – 3mm thick by pressing on each other.

• Importance of Head Gaskets

Engine cylinder block and head are two different engine parts. Both of them have different holes and passages. Through which the coolant and the oil properly flow. Since both the head and the cylinder block are metal parts, they require a seal that can be efficient even at high temperatures.

The head gasket contains holes and passages that resemble blocks and heads.
Coolant or oil can blend into the head if the gasket is blown or burned. It may burn in the cylinder. This causes the coolant to drop and the engine temperature to rise. There are many other implications that we will talk about.

• Symptoms of blown head gasket:

1 – Coolant leakage

If the coolant is constantly decreasing to some extent, understand that the coolant is leaking or that it is burning inside the cylinder block. Then the gasket may be damaged by increasing the engine temperature. If the coolant leak, show the car to the car mechanic immediately. Sometimes the coolant may leak inside and you won’t see it leaking visually.

2 – White smoke from the exhaust

The engine can work fine as long as it cools. But if that doesn’t happen,
then the white smoke will come out of the exhaust if the coolant is burned in the block. The main reason for this is a burnt or damaged gasket. If the gasket is damaged near the cylinder hole and the coolant passage is there, the coolant burns in the engine and leave the white smoke.

3 – Overheat engine

Although the temperature in the engine is suddenly increasing, there is a sign of gasket blowing and coolant reduction. If the coolant leaks from the outside, the engine won’t cool down so the gasket will burn due to high temperatures. If the temperature in the instrument panel is showing high, check the car immediately by showing it to the mechanic.

4 – Coolant got mixed with oil

If there is a broken or blown gasket which is exactly in the coolant and oil passage, the two fluids can mix together. At that point, two events can occur. In one combustion chamber, the mixture will burn and performance gets lowered. The compression will not be enough to maintain engine efficiency. Second, the properties of the coolant change when mixed with oil. Then the coolant will not cool the engine as much as necessary.

5 – Starting trouble

If the gasket is too burnt, the engine will not make the required compression to start the vehicle, so the car may not start quickly.

• Causes for Blown gasket

  • Radiator choke up –
    If the radiator does not stream the coolant properly, the engine will overheat and the head gasket will burn. Bad or contaminated coolant may be the reason behind the radiator choke up.
  • Coolant leakage or burn in the combustion chamber is the major reason behind the gasket malfunction causing the engine to overheat.

• Precautions to be taken –

  • Check the coolant level and coolant quality regularly.
  • Change the coolant at periodic maintenance.
  • Check the radiator flow pipes, coolant tank, and coolant system leakage at
    the service of your vehicle
  • Please notice the smoke of your vehicle.
  • If you want to change the gasket, please take care for manufacturer’s
    quality of gasket.

If the engine is too overheated then you have to pay a lot of money on the repairing of it. So prevention is always better than cure.
