How to Determine Engine Cylinder Head Gasket Failure?

[KeeganMarie]

Automotive cylinder head gasket failure refers to the rupture of the gasket between the cylinder head and the engine block, also known as gasket burn-through. Common symptoms of a blown head gasket include: reduced engine power, sluggish vehicle performance, bubbling or boiling in the radiator, white or blue exhaust smoke, and abnormal noises. The manifestations of gasket burn-through are as follows: 1. Burn-through between two adjacent cylinders: The engine lacks power, the vehicle performs poorly, and acceleration is sluggish. When removing the air filter, a "popping" sound can be heard at the intake pipe opening during engine idle. 2. Burn-through connecting to the water jacket: Bubbles appear in the radiator, coolant boils over, and white exhaust smoke is observed. 3. Burn-through connecting to the oil passage: Some engine oil enters the combustion chamber and burns, resulting in blue exhaust smoke. 4. Burn-through connecting to the external atmosphere: The engine exhibits poor performance, reduced fuel efficiency, and produces loud popping sounds from the damaged gasket area.
