A blown head gasket is a very serious issue that will lead to engine failure. The head gasket’s job is to seal the cylinder heads to the engine block and prevent coolant and oil from leaking into each other. When the head gasket blows, it loses its seal and can cause a host of problems. 

If you suspect that your head gasket has blown, it’s important to have it checked out by a mechanic as soon as possible. Blown head gaskets can often be repaired, but if they’re not caught in time, they can cause serious damage to your engine.

What Are The Symptoms Of A Blown Head Gasket?

  • Milky, creamy coloration in your oil.
  • Overheating engine
  • White smoke coming from the exhaust pipe (engine burning coolant).
  • Exhaust gas bubbling in the coolant reservoir.

These are the signs that there is a problem with the cooling system, and it’s likely that coolant is leaking from the engine. If left unchecked, a blown head gasket can cause extensive damage to the engine, so it’s important to get it fixed as soon as possible.

How Long Will Last A Car With A Blown Head Gasket?

A head gasket is a vital component of any car engine, and a blown head gasket can spell serious trouble. Many factors can contribute to a blown head gasket, including overheating, excessive wear and tear, and manufacturing defects.

In most cases, a blown head gasket will cause the engine to lose power and eventually fail altogether. However, there are some exceptions.

For example, if the head gasket blows while the engine is cold, it may simply result in a loss of compression. In this case, the engine may still be able to run, albeit less efficiently.

Ultimately, how long a car with a blown head gasket will last depends on the severity of the damage and the driving habits of the owner. If the driver is careful to avoid overheating and excessive strain on the engine, it may be possible to extend the life of the car by several thousand miles.

What Is The Cheapest Way To Fix A Head Gasket?

If your car is leaking coolant, it may be time to replace the head gasket and it is a pricey repair. But there is a way to save money on the process.

One option is to use a sealer.

A head gasket sealer is a product that seals leaks in the head gasket. It is a thick, viscous liquid that is poured into the engine through the radiator or the coolant tank.

It coats the inside of the engine. When the engine is started, the sealer hardens and creates a seal that prevents oil and coolant from leaking out. It also prevents exhaust gases from entering the crankcase.

A head gasket sealer is a temporary fix that can buy you some time before you need to replace the head gasket. However, it is not a permanent solution.

How Much Does It Cost To Replace A Blown Head Gasket?

Replacing a head gasket is no small task. The cost will vary depending on the vehicle.

On average, you can expect to pay anywhere from $2,500 to $8,000 for a head gasket replacement. If you’re faced with this repair, be sure to get multiple quotes from reputable mechanics before moving forward. By taking the time to do your research, you can ensure that you’re getting the best possible price on this crucial repair.

Is It Better To Replace The Head Gasket Or The Engine?

The answer depends on several factors, including the severity of the problem and the age and condition of your car.

If the head gasket is only slightly blown, then replacing it may be enough to solve the problem. 

However, if the engine heads are warped and can’t be machined then replacing the whole engine will be necessary.

In addition, if your car is relatively old or has high mileage, then replacing the engine may be a better option than trying to repair a damaged head gasket.

If your car is really old (more than 2~300,000 miles) then it may be better to cut your loss and get rid of the car.

Ultimately, the best way to determine what to do is to get a quote for all the options.


A blown head gasket is a very serious issue for an engine and should not be taken lightly. If you suspect that your head gasket has blown, it’s important to have it checked out by a mechanic as soon as possible to prevent any further damage.

Head gaskets can often be repaired but it is very expensive. If they’re not caught in time, they can cause serious damage to your engine.
