What happens when cylinder head gasKet goes?

A blown cylinder head gasket is a critical engine failure that can lead to catastrophic damage if left unaddressed. When the cylinder head gasket fails, it allows air, coolant, and combustion gases to mix, causing the engine to overheat, misfire, and lose power. It is important to take action as soon as possible if you suspect your cylinder head gasket has failed.

Common symptoms of a blown cylinder head gasket include:

- Engine overheating

- Exhaust smoke that is white, blue, or gray

- Oil that appears milky or foamy

- Coolant loss

- Poor engine performance

- Rough idling

- Engine misfires

If you experience any of these symptoms, have your car inspected by a trained technician as soon as possible. If the cylinder head gasket has failed, it will need to be replaced. This is a specialized repair that requires the removal of the engine's cylinder head, so it is important to only trust this work to a qualified mechanic.
