The Cylinder Head: Buying Guide

By Ruthie Calderon


In order to offer the required maintenance for your car, you have to understand it in and out. Just like you are your own first doctor, you are your car's first mechanic. With a deep understanding of smaller things that affects the engine performance. The cylinder head, or a "head" is perhaps one of the least understand the component and yet very important for car performance.

This is the part attached to the cylinder block that contains the cylinders and the pistons. The head gasket seals the blocks, thereby forming the combustion chamber which is the essential required to build the torque and the horsepower. The head plays an important role in allowing the inward flow of air-fuel mixture and an outward flow of the exhaust gases from the combustion chamber.

As such, before you make the purchase, you need to have the factors that affect its performance at the fingertips. The cylinder block is the main part of the car engine and contains the cylinders and the pistons.

In order to choose the right cylinder cap for your car, the engine is the first thing to consider. In case you are buying one to replace the damaged one, you have to take the note of the engine. This ensures that your choice is able to perfectly fit the engine design and type. In most cases, your engine specifications will narrow your options to just a few types.

When it comes to design and complexity, it varies depending on the engine. In most cars, a single head is enough. The V-engines on the other hands have two heads to fit into the two cylinder banks which are part of the V. In the case of trucks and tractors, each cylinder has a head for ease of repair and general maintenance.

The maintenance is the other important aspect to understand for optimal engine performance. The heads have many passages that can allow fuel flow which make clogging with residues common. When it is dirty and clogged, the engine performance drastically reduces. As such, the cleaning of this component is part of the routine maintenance program. There are several tips that can be helpful when cleaning.

In order to prevent residue from building up, the cleaning sessions need to be regular. It helps the caps and the engine as a whole to last longer. Failure to observe a more frequent cleaning routine means that you may have to make a replacement sooner than normal. It is necessary to use solutions such as aqueous solvents or other authorized solutions to help remove the sludge.

The other factors to look at include the valve or port flow capability that determines how free flowing the ports and the valves are in the engine, the mixture motion (the motion of incoming fuel and air mixture), and the material. It should be made of a more rigid and strong material so that it can effectively and uniformly distribute the forces which in turn facilitates fuel combustion.
