What is a blown head gasket?

A blown head gasket is a breach in the gasket whose purpose is to form a gas-tight seal between the cylinder head and the engine block. This type of breach typically occurs in cars that have severely overheated. During severe overheating, the head or block warps, pulling away from the gasket. The unsupported gasket fails under the high pressure of combustion or heat from the cooling system. Once the gasket is penetrated, exhaust gasses escape from the cylinders into water cooling ports and often into adjacent oil ports. When this happens, the cooling system malfunctions, causing the engine to overheat.

What are the symptoms of a blown head gasket?

The most visual sign of a blown head gasket is steam visible from the tail pipe after the car is warm. However, many cars with minor damage to the head gasket don’t show any visual indicators. In this case the cooling system must be checked for the presence of exhaust gasses. Another symptom frequently encountered is water in the oil. It appears as a milky white emulsion under the oil cap and on the dipstick.

How does Thermagasket work?

Whenever there is a breach in the head gasket, a cracked head or cracked block, a hot spot develops at the point of the breach. That hot spot can reach temperatures 3 to 4 times that of normal engine operating temperatures. When Thermagasket comes into contact with this superheated area, it instantly forms a perfect high-temperature seal. Once the breach is sealed by Thermagasket’s metallic alloys, heat is deflected away from the patch, eliminating the hot spot and preserving the long term integrity of the repair.
