What is Cylinder Head?


In an engine, the top of the cylinder is closed with a separate cast piece called the cylinder head. The cylinder head is bolted to the upper part of the cylinder block. This joint is covered by a head gasket. It consists of a combustion chamber, spark plugs, and sometimes valves (in the I and F-heads).


In most engines, the cylinder head includes passages that deliver air and fuel to the cylinders, and which allow exhaust gas to exit. The cylinder head is usually made of gray iron or aluminum alloy. Aluminum has the advantages of being lightweight and having high thermal conductivity.


Remanufactured Cylinder Head

With a remanufactured head, every single component will be replaced, all to new specifications. This process involves casting, machining, cleaning, installing new parts, and testing. In other words, a remanufactured head will go through all the steps that it is supposed to be in factories. Those are the reasons why remanufactured cylinder heads usually cost more.


Let’s examine the most common cause of engine breakdowns, cracking of the cylinder head. While welding is what mechanics would do to heal cracks when rebuilding cylinder heads, recasting is the technique in the remanufacturing process. New molten metal is poured into the cracks, which make it meet the original specifications of your engine. Therefore, casting is much stronger than welding, so fewer chances that cracks will be opening back up again.


Cylinder Head Threads Issue

The threads on the cylinder head are sometimes too short and soft, which allow pressure from combustion to overwhelm and destroy the threads. That causes the cylinder head to become damaged, necessitating repair of the spark plug port threads, or replacement of the cylinder head and cylinder head gasket.


As you are deciding to repair your engine cylinder heads, we recommend that you consult a professional company. Depending on the current status of your engine, your intention, and your budget, a trustworthy mechanic will provide an answer to meet all requirements.
