Cylinder cover is the main part which handles most of the thermal load in its combustion chamber. Because of that thermal load, it is water cooled on many different locations. Both the thermal load and water can create damages on the cylinder cover. In the combustion chamber, there can be heat cracks in and around the injector holes as well as some other cracks on different locations. Also, there can be corrosion on the water jacket o-ring grooves area and exhaust seat bore area due to water circulation. Depending on the damage of the given part, Matra offers different types of reconditioning to solve these issues (partial and full). All these types of reconditioning covers the full needs of your cylinder cover.
