How To Choose Gaskets For A Car And What Is Their Role?

Posted Leave a commentPosted in Gaskets For A Car

In most cases, gaskets for cars have a major role, regardless of their area of ​​use (parts for which they are intended). Automotive gaskets ensure the tightness (connection) of mechanisms. They also serve to protect against moisture ingress. Simply put, car gaskets play an important role.

Why else do you need spacers in the car? They are suitable for those cases where two adjacent surfaces are uneven and poorly processed. The pliable and soft gaskets take the product’s shape well and smooth out the existing roughness and irregularities.

To clearly understand what a gasket in a car is for, an example should be given. In particular, in the “heart” of the machine, the engine, various fluids are constantly circulating. Many of them are under pressure. To maintain it at the required level, complete tightness must be ensured. Engine gaskets are irreplaceable in this case. They allow sealing (connected parts or) a spare part, thereby preventing leaks.

Types of gaskets

If we talk about choosing gaskets in a car, it is important to consider their varieties. It is the type of pad that directly affects which pad you need to buy.

When talking about material and form, one point should be clarified. These parameters depend on the technical characteristics of the material with which the product is to come into contact. Also, not the last factor influencing the choice of gaskets in the car is their goals.

As for the types of gaskets, they are conventionally divided into 3 categories:

The first type is suitable for preventing leakage, as well as retention of various technical fluids. Among the latter, engine oil or coolant should be distinguished.

The second type is a kind of sealant. The role of such car gaskets is to seal the abutment points. They also resist pressure and high temperatures. For example, they are installed as a cylinder head gasket.

The third type is called oil seals. Such seals need to be purchased to protect the places where fixed parts come into contact with movable ones.

As for the forms of gaskets for cars, there is no uniform solution here. Manufacturers produce parts with various shapes and surfaces. If you need to buy and replace a car gasket, you should order a new one recommended by the car manufacturer.

What other types of gaskets are there?

There is another division of car gaskets according to their place (used in a car) location. So the most demanded of them are:

Cylinder head gaskets

Among all gaskets used in a car, special attention should be paid to products for cylinder heads. Such products are high-tech and highly sophisticated. What are cylinder head gaskets made of? Most often, their structure is very complex. For their manufacture, paronite, fiber, cork, cardboard (special), etc., are used.

Intake and exhaust manifold gaskets

Such gaskets in the car are located where the manifold is connected to the cylinder block. For the intake manifold, products made from compressed cardboard are suitable. In the exhaust manifold, more durable materials must be used, as there are elevated temperatures in this area. For these purposes, in most cases, gaskets made of metal or asbestos-free paronite are used. Metal-asbestos

Cooling system gaskets

Cooling system gaskets are extremely important for the proper (engine) function of this unit. They allow you to maintain a normal operating temperature in the cylinder block. This equipment consists of several units connected. The gaskets make it possible to guarantee complete tightness at the joints (units of the cooling system). What materials to choose, such as gaskets for a car? Synthetic rubber (silicone) is most often used here. It is not subject to the negative effects of low temperatures and direct exposure to oils and liquids.

Choosing the right gasket for your car is easy. If you have difficulties with this, you can always get help from more experienced professionals service such as Gorilla Gaskest’s custom Viton FKM Gaskets.

Cylinder Head Gasket Burned Out: Malfunction Symptoms

The cylinder head gasket is responsible for the tightness of the connection between the cylinder block and the cylinder head. The specified gasket makes it possible to realize the sealing of the combustion chamber and the cooling jacket’s channels, along which the coolant moves. The gasket can be made of thin metal. The second available option is reinforced paronite, which has a metal edging in those places where holes for the combustion chamber are made in the gasket.

Burnout or breakdown of the cylinder head gasket is a serious and fairly common malfunction. The obvious answer to whether it is possible to drive with a punctured cylinder head gasket is the need for urgent repairs. With a slight loss of tightness, it should be added that it is possible to move under its own power in a car, but it is advisable to eliminate such a defect urgently. If the cylinder head gasket is severely punctured and signs of breakdown are clearly visible, the internal combustion engine’s operation is prohibited.

Causes of breakdown and how to check the cylinder head gasket

The engine’s consequences can be disastrous even when driving a car with this problem for a short time. If the breakdown of the cylinder head gasket is ignored, a major overhaul becomes necessary even after a small mileage.

The specified breakdown can occur in both a gasoline and a diesel engine, a turbocharged unit, or an atmospheric version. Breakdown of the gasket requires correct and timely diagnosis. An increase in fuel consumption, difficult engine starting and unstable operation, a decrease in the internal combustion engine’s power, a drop in the level of coolant in the expansion tank, and low compression in the cylinders can indicate a problem at an early stage.

The most common causes of breakdown or burnout of the cylinder head gasket are:

  • overheating of the engine;
  • incorrect installation when replacing the gasket;
  • the consequences of the power tuning of the internal combustion engine;
  • inappropriate tightening torque of the cylinder head bolts;
  • driving on low-quality gasoline, which is accompanied by detonation ;

Engine overheating is the main cause of cylinder head gasket breakdown. Engine overheating occurs for various reasons, ranging from a malfunction of the cooling system and ending with such phenomena as engine detonation or glow ignition. Both metal (asbestos) gaskets and paronite gaskets under such conditions usually do not withstand the rising temperature during overheating and burnout. After such a burnout, the strength of the gasket becomes less, and it is blown out.
