Description

Function of Cylinder Head

The cylinder head plays an important role in a motor vehicle. The structure of the cylinder head is complex and consists of many ports. One of these ports is designed to work, and their common roles explain the value of this engine part.

It provides the mounting for various components such as inlet and outlet exhaust valves and ducts, spark plugs, fuel injectors, and camshafts. In addition, it gives way to coolant, oil, and combustion gases.

The cylinder block absorbs the heat produced by the engine and, therefore, generates cooling to prevent engine failure. It seals the combustion chamber and serves as the engine’s mechanical control powerhouse. It also takes away the compression resulting from the combustion pressure.

What Are the Symptoms of a Cracked Cylinder Head?

Symptoms of a cracked cylinder head are identical to those of a blown head gasket and include engine misfires, leaking oil that drains from the engine and the seemingly unexplained presence of coolant fluid in engine oil. Cracks in a vehicle’s cylinder head may be large enough to see or may be invisible to the naked eye, and diagnosis of this issue as opposed to issues with similar symptoms, such as a blown head gasket, requires specific techniques including the use of dye and pressure to expose the cracks. Because it can be easily confused with other issues, diagnosing a cracked cylinder head requires more than simple knowledge of symptoms.

Cracking is a common problem for cylinder heads, and these cracks cause openings between different chambers in an engine. The exact nature of the damage to the cylinder head or head gasket will control the type of symptoms that show as a result of this damage, meaning that symptoms can vary. Cracks in cylinder heads can be fixed, or the cylinder head can simply be replaced if repair is not plausible. Thermal stress as a result of overheating or coolant loss is a leading cause of cracking cylinder heads; the cracks come about as a result of the natural expansion and contraction in metals.
