Presentation Description

There are certain components in your car which are vital for the smooth functioning and better performance of the car. The head gasket is an important component which forms a seal between the engine block and the cylinder head. This is a very important function as it seals both extremely hot, high-pressure combustion gases as well as the engine coolant. If it malfunctions, then it will affect the smooth running of the car. Go through the slide to diagnose a blown out head gasket.

How to Diagnose a Blown Out Head Gasket

Slide2:

The head gasket forms a seal between the engine block and the cylinder head of your car.

Slide3:

Their main function is to keep the heat and high-pressure combustion gases as well as the coolant intact within the system.

Slide4:

The frequent exposure to extreme temperatures makes the head gasket vulnerable to wear, and may even blow out.

Slide5:

As the gasket is not visible, it is very hard to diagnose a blown out head gasket.

Slide6:

So, it is required to know the common signs of a blown out head gasket, which are: Overheating of engine Bubbles in radiator Milky engine oil Bad spark plug White smoke from exhaust

Slide7:

Overheating of engine

Slide8:

The engine starts to overheat after long drives because of the lack of coolant which makes the radiator inefficient.

Slide9:

Such overheating results in damage to the seals and gaskets which causes leaks in your engine.

Slide10:

Bubbles in radiator

Slide11:

Leakage of exhaust gases into the coolant can cause bubbles in the radiator.

Slide12:

Actually, these bubbles are exhaust gases that force their path into the cooling system during the combustion process.

Slide13:

Milky engine oil

Slide14:

When the coolant gets mixed with the engine oil, the color of the oil turns to milky white.

Slide15:

You can easily check the color with the help of the dipstick and by looking around the engine oil cap.

Slide16:

Bad spark plug

Slide17:

Burning of coolant in the combustion chamber damages the spark plug of your car.

Slide18:

Carbon gets deposited around the ground strap and the electrode, which is a possible sign of a blown out gasket.

Slide19:

White smoke from exhaust

Slide20:

When the coolant burns along with the combustion gases, then it results in a cloud of white smoke from the tailpipe.

Slide21:

The white smoke can be easily differentiated from moisture during a cold start by a sweet smell.
