Superior Durability: Steel engine cylinder head gaskets offer exceptional durability and resilience. They're designed to withstand high temperatures and pressures within the engine, ensuring a long-lasting seal compared to other materials.
Enhanced Sealing Properties: The steel construction provides excellent sealing properties, minimizing the risk of leaks between the cylinder head and engine block. This helps maintain proper compression and keeps coolant or oil leaks, ensuring optimal engine performance.
For High-Performance Engines: Steel cylinder head gaskets are capable of withstanding greater power and pressure. They provide a reliable seal, making them ideal for engines with higher compression ratios or forced induction settings.

Product Description

Failure performance after the cylinder gasket washed out，Due to the cylinder gasket burned position is different, the signs of failure are different:

1.:the neighboring two cylinders between the gas.

In the premise of not opening the decompression, shake the crankshaft, feel the pressure of the two cylinders are not enough to start the engine work with the phenomenon of black smoke, the engine speed dropped significantly, showing the lack of power.

2:Cylinder head leakage

Compressed high-pressure gas into the cylinder head bolt holes or by the cylinder head and the body of the combination of surface leakage. Leakage is shown at the presence of yellowish foam, serious leakage will be issued when the "Vish" sound, sometimes accompanied by water leakage or oil leakage, disassembly and inspection can be seen in the corresponding cylinder head plane and its neighboring cylinder head bolt holes have obvious carbon deposits.

3:gas oil oilway

High-pressure gas into the engine body and the cylinder head connected to the lubricating oil oil channel. Oil sump oil temperature in the engine has been running high, oil viscosity thinning, pressure reduction, deterioration of fast, sent to the upper part of the cylinder head lubrication of the gas distribution mechanism of the oil is obviously with gas bubbles.

4:high-pressure gas into the cooling water jacket

In the engine cooling water temperature is lower than 50 ℃, open the water tank cover, you can see the water tank in the more obvious bubbles rising out, accompanied by a large number of hot air from the water tank mouth, with the gradual increase in engine temperature, from the water tank mouth of the hot air also increased one after another. In this case, if the water tank overflow pipe blocked to the water tank full of water to cover the mouth, you will see the phenomenon of bubbles on the phenomenon is more pronounced, and in severe cases will also appear as the phenomenon of boiling.

5, the engine cylinder and cooling water jacket or lubricating oil channels run through

Will be in the tank cooling water on the surface of the floating yellow and black oil foam or oil in the oil sump in the oil is obviously water, when the two kinds of gas phenomenon is serious, will make the exhaust with water or oil.

Why can I buy GXARTS Cylinder Engine Multiple Layers Steel Head Gasket with confidence

Superior Durability:

Steel engine cylinder head gaskets offer exceptional durability and resilience. They're designed to withstand high temperatures and pressures within the engine, ensuring a long-lasting seal compared to other materials.

Enhanced Sealing Properties:

The steel construction provides excellent sealing properties, minimizing the risk of leaks between the cylinder head and engine block. This helps maintain proper compression and prevents coolant or oil leaks, ensuring optimal engine performance.

Resistant to Warping,Compatibility and Precision Fit:

Steel gaskets are less prone to warping or deformation, even under extreme operating conditions. This characteristic maintains a consistent seal and prevents the loss of compression between the cylinders.Quality steel gasket sets are precisely engineered to match specific engine configurations.

Suitability for High-Performance Engines:

Steel cylinder head gaskets are often preferred for high-performance engines due to their ability to handle increased power and stress. They offer a reliable seal, making them ideal for engines with higher compression ratios or forced induction setups.
