Mazda 3 Cylinder Heads

A cylinder head is a complex assembly whose design greatly influences the performance, lifespan, and overall reliability of the engine. In the DOHC engine of your Mazda 3, the head not only tops the combustion chamber but also contains the valvetrain system and numerous channels filled with cooling fluid. In direct-injected motors, the head also serves as a base for fuel injectors. Over time, the assembly may start malfunctioning; some issues are caused by carbon deposits on the valves, others can be explained by the wear of valve seals or their guides, still others occur due to a leaky cylinder head gasket, etc.

The factors negatively affecting the performance and lifespan of the head include the lack of lubrication, overheating, improper air-fuel mixture, constructional drawbacks, various defects, etc. Given the complexity of repair, it often makes sense to install a remanufactured head rather than try to restore the existing one.
