At BLUMAR MARINE, we provide expert overhaul services for cylinder covers and cylinder cover jackets to ensure reliable engine performance and extended durability of critical components. During the cylinder cover overhaul, the component is carefully dismantled and cleaned to remove carbon deposits and contaminants. A detailed inspection is carried out to check for cracks, deformation, or excessive wear, particularly on the valve seat areas and cooling passages. Pressure testing of the cooling channels is performed to detect any leaks or blockages, ensuring proper cooling efficiency.

Key measurements, such as warpage of the sealing surface, are taken to verify that the cylinder cover meets the required specifications. If necessary, resurfacing is performed to restore the sealing integrity. The fuel injector and exhaust valve pockets are inspected and overhauled to maintain optimal combustion performance.

For the cylinder cover jacket, the cooling water passages are cleaned, inspected, and pressure tested to identify and address potential issues such as scaling or corrosion. Worn or damaged components, including gaskets and sealing rings, are replaced as part of the reassembly process. Following the overhaul, functionality tests are conducted to confirm proper operation, ensuring that the cylinder cover and jacket provide efficient cooling and sealing for the engine.
