Description of Used Engine Heads
How are cylinder heads attached to the engine block?
Large vehicles usually cylinder heads as separate pieces that mount on the engine block by means of bolts or studs. Usually, the type of engine determines the kind of cylinder head to use. Inline engines use one cylinder head, while V and Boxer engine types have two different heads.
Cylinder Head Function
1. Provide the mounting structure for various components such as the inlet and outlet exhaust valves and ducts, spark plugs, injectors, and (in some head designs), the camshaft.
2. Contain the passages for coolant, oil, and combustion gases.
3. Dissipate the heat produced by the engine and, therefore, produce cooling.
4. Act as the combustion chamber seal and the engine’s mechanical control powerhouse.
5. Take the compression resulting from combustion pressure.
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.
