Cylinder heads are usually located on the top of the engine block.

A cylinder head serves as a housing for components such as, Intake and exhaust valves,  Camshafts, Valve Springs And Lifters.

Most (OEM) cylinder heads are made out of cast-iron. A cylinder head made of cast-iron is more durable and less expensive. However, cast-iron is heavy and provides a lesser efficiency in dissipating heat.

For this reason, some manufacturers prefer using cylinder heads made of aluminum. These cylinder heads are much lighter than cast-iron cylinder heads.

Problems in Cylinder Heads and their Symptoms

The most common problem with cylinder heads is cracks that occur often due to engine overheating. A cracked cylinder head may leak the coolant, due to which the engine will fail to cool efficiently. This results in further overheating of the engine.

When a cylinder head cracks, it will also cause the oil to leak into the combustion chambers. This can be detrimental to the engine and can result in costly repairs for the engine. In many of these cases, the entire engine will have to be replaced. Other symptoms of a bad cylinder head include poor engine performance and engine misfire.

When a car overheats, a lot of people fill water in the radiator without attempting to narrow down the actual problem. This can also cause the cylinder head to crack, since when water is added, it results in a rapid change in temperature.
