What is a head gasket?
The gasket that sits between the cylinder heads and the engine block is a head gasket. The function of the head gasket is to seal the cylinders so that the engine oil or the coolant does not leak into the cylinders which in turn ensures maximum compression. It is an integral sealing application in an engine. You should get a radiator stop leak too in case you don’t wanna run into a problem of coolant leakage
In case of a blown head gasket, several problems can arise. The car can lose compression or the exhaust gases can leak into the cooling system causing the engine to overheat and eventually be worn down. A head gasket repair is suggested as soon as you experience any symptoms of blown head gasket.
How to tell if head gasket is blown:
After some mileage, most cars are likely to experience bad head gasket symptoms. The signs of a bad head gasket are pretty evident if you know what you’re looking for. In case you’re wondering what is a blown head gasket, these are the signs of a leaking head gasket:
- Overheating engine
- Leaking coolant from below the exhaust manifold
- Fouled spark plugs
- Vulnerable cooling system integrity
- White smoke from the exhaust pipe
- Bubbles in the coolant overflow tank or the radiator
These are the indications of how to check for a blown head gasket. If your vehicle shows signs such as these it most likely hints at a blown head gasket.
