Description

 

Types Of Cylinder Heads


Flathead Cylinder Heads: These were the first type of cylinder heads. Flathead cylinder heads simply protect the cylinder block and have no moving parts. These cylinder heads do not allow for an efficient air flow, and thereby provide a poor engine performance.


Overhead Valve Cylinder Heads: These cylinders heads are superior to flathead cylinder heads. Overhead valve cylinder heads have the camshafts above them. These heads have their pushrods and valves connected to provide a smooth airflow.


Overhead Camshaft Cylinder Heads: These are the most advanced designs of cylinder heads. Overhead camshaft cylinder heads have the camshafts inside the cylinder head, eliminating the need of pushrods. This provides a better airflow, and in turn, increases the efficiency of the engine.

 

Why Do Cylinder Heads Fail?


The most common reason for cylinder head failure is overheating caused by, for example, coolant loss, head gasket failure, or restricted flow of coolant.


In extreme cases, a cracked or damaged cylinder head can result in terminal damage to the entire engine! You must deal with any problems as soon as possible to try and prevent this from happening.


Cylinder heads can also warp because of the tremendous pressure placed on them by extreme temperature changes. This means that it is no longer providing a flat surface to hold the head gasket in the right position, which can lead to expensive problems later on in the form of major repairs or total engine replacement being required.

 

Warping is a particular problem for cylinder heads made of aluminum. Different engines have different levels of tolerance for cylinder head warping – some can withstand a high amount of warping while still working effectively. If your cylinder head does warp, you may be able to take it to a mechanic who specializes in realigning them – if not, you will probably need a replacement.
