At BLUMAR MARINE, we perform comprehensive exhaust valve overhauls to ensure the optimal performance and longevity of your engine. During the overhaul, the exhaust valves are carefully removed, and each component is inspected for wear, corrosion, or damage. The valve seats and sealing surfaces are thoroughly examined to ensure they meet manufacturer specifications. If any defects are found, these components are machined or replaced to restore sealing efficiency and maintain optimal combustion performance.

The valve springs, guides, and retainers are also inspected for wear and replaced if necessary to ensure proper valve function. The exhaust valve stems are measured for any signs of bending or wear, and any issues are addressed to prevent valve failure during operation. The valve discs are cleaned and polished to remove carbon buildup and improve seating performance.

Additionally, the valve stems and guides are lubricated, and proper clearance is confirmed to ensure smooth operation. After reassembly, we conduct a full set of functional tests, including pressure testing, to ensure that the exhaust valves provide a tight seal and operate within optimal parameters.
