How to Tell if You Have a Cracked Head Gasket

Blowing your head gasket is a common problem for motorists – especially if you have an older car. If you're not careful this can result in damage to the engine and high head gasket repair costs. You could even require a mechanic to replace the head gasket entirely, for no small cost.

Luckily you can identify a number of common symptoms of a blown head gasket early on –  providing the opportunity to save yourself time, money and hassle.

What are the symptoms of a blown head gasket?

Having trouble with your car, but not sure if your head gasket is the issue? You may want to look out for these common signs of a blown head gasket:

An engine is topped up with coolant.
Radiator constantly needing to be topped up with water or coolant.
A dashboard indicator shows that a car's engine is starting to overheat.
Increased engine running temperature.
An engine warning light on the dashboard indicates the engine is overheating.
Engine gauge showing maximum temperature after a few minutes.
An oil filler cap is held up to show discolouration of the oil.
Oil has a milky discoloration (here on an oil filler cap).

The final, most noticeable symptom is a big cloud of smoke pouring from the exhaust, and the engine gauge showing maximum temperature after a few minutes. Unfortunately, these symptoms often arrive when it is too late to sort the problem out.

Why you shouldn't ignore blown head gasket symptoms

It's not unusual to ignore these symptoms, as many drivers simply don't want to even think about the cost of potential repairs. However, leave it too long and a blown head gasket could cause major damage to your car.

For example, changes in coolant temperate and coolant leaks could:

  • Ruin the engine thanks to coolant leaking into the engine oil
  • Erode the lubrication of the engine
  • Damage the catalytic converter
  • Cause the engine to overheat through the mixture of coolant and combustion gases

In the long run, this will end up costing you far more than fixing the leak at the first sign of an issue – especially as an overheating engine could lead to even more problems:

  • Damage to the cooling system
  • Failure of the radiator
  • Erosion of the hoses

Common symptoms that get wrongly attributed to a head gasket leak

A lot of issues with head gaskets are similar to symptoms for other engine problems. This means it's fairly common for the following engine problems to be wrongly diagnosed as a blown or leaking head gasket.

Coolant in the oil

Although head gasket failure is often blamed for coolant leaking into your oil, it may be due to problems with the intake gasket.

Engine overheating

A leaking or blown head gasket will cause your engine to overheat over time, but this overheating could also occur due to a restricted radiator instead

If this is the case, an accurate diagnosis of the engine problem will rely on the expertise of a skilled mechanic.
