The cylinder head along with a gasket reside on top of the engine and create a vacuum so that air and fuel can be compressed and the combustion process can commence. Cylinder heads are often lightweight and can become susceptible to damage; however, cracks or leaks in your car’s cylinder head can cause catastrophic damage to your car’s engine resulting in costly engine repairs or replacements. A cylinder head that is cracked can cause the engine to perform poorly, overheat, or fail all together.
The cylinder head is one of the most vital parts to your car’s mechanics; your gas-powered car could not work without it. The cylinder head and head gasket sit atop the engine block over the cylinders. The head covers and protects the engine components and creates the correct vacuum for the engine to work.
