Reconditioning a marine engine’s cylinder head is a precise, multi-step process that restores OEM performance and reliability. It includes complete disassembly, thorough cleaning to remove carbon and contaminants, and pressure testing to identify cracks or leaks. The head is then machined to restore flatness, and critical components—valves, valve seats, and valve guides—are refurbished or replaced as required. Key operations include surface grinding, valve-seat regrinding, valve and guide replacement, and leak checks to ensure a perfect combustion-chamber seal. The result is optimal engine efficiency, stable operation, and extended component life.
