Blown cylinder head gasket: What does this mean for you and your car? 

Cylinder head gasket defective? What you need to know now!

When talking about car problems, a defective cylinder head gasket sounds like the worst news. And yes – this small seal in the engine compartment can have a massive impact on your car's performance if it is defective. In this article, you will find out how important the cylinder head gasket is, what signs indicate a defect and what options you have if it breaks.

The role of the cylinder head gasket: Why is it so important?

The cylinder head gasket is an essential component located between the engine block and the cylinder head. It ensures that three important systems in the engine – oil, coolant and combustion gases – remain separated from each other. A broken cylinder head gasket means that these systems can mix together, which quickly leads to major damage.

What can damage the cylinder head gasket?

There are a few common causes that can lead to a cylinder head gasket failure:

1. Engine overheating: An overheated engine is one of the main causes of a broken cylinder head gasket. Causes of overheating are often a defective thermostat, a leaking water pump or a blocked radiator.
2. Natural wear and tear: Over time, the cylinder head gasket can become brittle and leaky. This happens due to constant temperature changes and the general stress on the engine.
3. Errors during installation: Sometimes the gasket is not installed correctly during a previous repair or engine rebuild, which leads to increased pressure and ultimately to damage.

Defective cylinder head gasket: signs and symptoms

A cylinder head gasket defect often manifests itself in various ways. Here are the most common symptoms you should be aware of:

1. Loss of power: If your car no longer pulls properly or the engine reacts sluggishly, this can be a sign of a defective cylinder head gasket. The lack of compression in the cylinders means that the engine is no longer working optimally.
2. Discolored coolant: Coolant that suddenly looks like chocolate milk indicates that oil and coolant are mixing – a clear sign of cylinder head gasket damage.
3. White smoke from the exhaust: If white clouds of smoke rise from the exhaust, this may indicate that coolant is entering the combustion chamber and being burned there. This is a classic symptom of a broken cylinder head gasket.
4. Engine overheating: A sudden rise in engine temperature or constant overheating can indicate a defective gasket, as the coolant can no longer circulate effectively in the engine.

Repair or sale: What is worthwhile?

If a cylinder head gasket is broken, there are two options: Repair or sell. But which makes more economic sense? Here is an overview of the options:

Option	Costs	Advantages	Disadvantages
Cleaning the cylinder head gasket	50€ - 100€	Inexpensive repair option	Does not always work
Replacing the cylinder head gasket	400€ - 1.200€	Problem is fixed	High costs, especially for older vehicles
