* Engine overheating: A head gasket leak can allow coolant to leak into the cylinders, which can cause the engine to overheat. This can damage the engine's pistons, valves, and cylinder walls.
* Loss of compression: A head gasket leak can also cause the engine to lose compression. This can reduce the engine's power and efficiency.
* Oil contamination: A head gasket leak can allow oil to leak into the coolant. This can contaminate the oil and reduce its effectiveness.
* Engine failure: If a head gasket leak is not repaired, it can eventually lead to engine failure.
In addition to these problems, a head gasket leak can also cause a number of other symptoms, including:
* White smoke from the exhaust
* Bubbles in the coolant reservoir
* Overheating
* Loss of coolant
* Loss of power
* Rough idling
If you experience any of these symptoms, it is important to have your car inspected by a qualified mechanic as soon as possible. Head gasket leaks can be serious, and they can cause significant damage to your engine if they are not repaired promptly.
