Now the modern vehicles like Porsche have four-stroke engines that will need 3 types of fluid to run efficiently such as the coolant, engine oil, and combustible air-fuel. All vehicles have a component known as a head gasket that ensures that all fluids are properly circulated between the components without mixing with each other.

Apart from the mixing of fluids, the head gasket also prevents the buildup of residue on the engine and keeps the engine free from the things that are catching fires. Like other vehicle components, the head gaskets also wear out over time due to age and use. So, don't forget to inspect the head gasket of Porsche on scheduled maintenance.

What do you mean by head gasket?

In a Porsche, the head gasket is the most vital component in the combustion chamber which is located in between the cylinder head and the engine block. It is defined as a seal for preventing the leaking of engine fluids into the cylinders. Moreover, it is represented as a barrier to the cylinder and blocks off the oil and water.

Due to its position, the temperature of the head gasket fluctuates that would be ranged from the high heat of the combustion process to the cold temperature of the cooling system. Over time, the impacts of temperature wear out the head gasket and cause leaks in the crucial areas.

Causes behind a blown head gasket

All the parts and components of the Porsche are designed differently with unique operating characteristics. So, the head gasket is also blown in your vehicle for numerous reasons such as:

l Overheating is the main cause behind blown head gasket means when the engine is running hotter than its specified temperature, it will break down the gasket materials and blown it eventually.

l Thus, the high boost levels will increase the cylinder pressure and lead to a blown head gasket.

l Subsequently, when the engine is performed for longer with high RPM it will produce excess heat and cause a blown head gasket as well.

l Downshifting and sudden engine braking in manual transmission cars can put excess pressure on the head gasket and blow it over time.

Don't drive the Porsche with a blown head gasket because it will damage the engine badly and leave you stranded on the road. Consult with a mechanic to inspect the head gasket and replace it with a new one.

Signs of blown head gasket

Moreover, the repairing cost of the blown head gasket is very high. So, every car owner tries to avoid it by consulting with a professional technician. The following points define the signs of the blown head gasket in Porsche.

Rough idling

Moreover, the engine of the highly technological vehicles is designed in such a way to maintain the high-pressure level inside each cylinder for increasing its power and efficiency.

When the head gasket of the vehicle is blown between the coolant channels and the combustion chamber, the engine unable to hold the pressure properly, run poorly, and idle roughly.

Startup troubles

In general, the engine of the Porsche is producing a lot of heat as it is running through a series of high-powered operations. In this process, the cylinder needs to be cool properly for preventing major engine overheating.

But, when the head gasket of the car is failed, the engine is overheated and produces white exhaust fumes from the engine. Neglecting the problems for longer may cause startup troubles and lead to costly engine repairs.

Blue exhaust fumes

Apart from the white exhaust smoke, the blown head gasket also produces blue exhaust fumes when the engine is burning oil. When the oil is leaking from the pistons and into the combustion chamber, then brings it to a reputed mechanic as soon as possible.

On the other hand, blue exhaust fumes are the warning sign that raises a warning flag in the Porsche. Subsequently, the wear-out head gasket will produce thick and smokey exhaust fumes from the engine which is clearly noticeable.

Loss of power

When the head gasket of the Porsche is blown, you will feel a substantial loss of power suddenly while stepping on the gas pedal. Moreover, the power loss problems in the car do not occur while driving. Thus, power loss problems are also arising when the head gasket fails between the cylinders.

The failed cylinders will affect the compression in the engine. On the other hand, the loss of power may affect the lack of coolant to get into the cylinder and interrupt the combustion process may lead to power loss.

Engine overheating

The main purpose of the head gasket is to keep the coolant flowing through the engine and overheat the engine when it has leaks. Thus, the blown head gasket will cause engine overheating problems in Porsche. When the head gasket is leaking, it will warp the engine parts and produce an oil-burning smell.

In this condition, the engine temperature warning light is illuminated on the dashboard and affects your driving. Apparently, the overheated engine can fail the engine quickly.


When the head gasket of your Porsche is blown, try to inspect it as soon as you can. If you are living in Tempe, then consult with a reputed mechanic for diagnosing the head gasket and replace it if necessary.
