What Is a Head Gasket?

A head gasket, which functions as a reliable seal, fills the area between the engine block and the cylinder head. In addition to sealing combustion gases inside the cylinder, it also achieves the pivotal purpose of preventing coolant from leaking into the combustion chamber.

Your automobile can shut off as a result of an overheated engine and diminished performance brought on by a broken head gasket.

The process of spotting a ruptured head gasket requires a lot of time and skill.

Symptoms of Bad Head Gasket:

Here are eight common indicators of head gasket issues.

Engine Oil or Coolant Leakage:

Look for the head gasket leak e.g. oil leaks or coolant leaks around the engine head or engine block, indicating a compromised head gasket with no proper sealing.

Engine Overheating:

A damaged head gasket can impede the engine’s cooling process, leading to overheating and potential damage.

Remember if your head gasket blows, engine won’t cool itself specially at driving level. Overheating can be the reason of severe and serious engine damage. Never remove radiator cap and check engine coolant if your car is overheating.

Engine Misfiring:

For engine, spark, air and fuel is must. A faulty head gasket can cause engine misfires.

Engine Block or Cylinder Head:

Warping cylinder head or engine block can disrupt the necessary flat surface for the head gasket, possibly resulting in failure. Broken head bolt can also cause damage. Consider this when the head gasket is broken in two cylinders of the same engine head.

White Smoke:

White smoke or water vapor from the exhaust suggests coolant entering the engine due to a damaged head gasket. You may experience white smoke or water vapor from exhaust pipe. If you witness blue smoke, it usually means that oil is leaked.

Milky-Colored Engine Oil:

The presence of milky-colored engine oil indicates contamination due to coolant mixing with oil, often caused by a blown gasket.

Spark Plug:

Coolant, oil, or gas entering the cylinders can flood the spark plugs that can lead to serious danger.

Bubbling in Radiator:

Air in the coolant system, caused by combustion gases escaping through a blown head gasket, may lead to bubbling in the radiator. Bubbling inside the coolant reservoir can be a serious indication as it indicates air in system leads to blown head gasket.
