🔌 Function

The inner cover forms the exhaust passage inside the cylinder and crankcase assembly. It separates the hot exhaust stream from the surrounding cooling-water jacket and helps maintain the intended exhaust and cooling-water flow paths.

⚠️ Common Signs of Failure

• Corrosion or pitting around the cooling-water passages
• Exhaust or cooling-water leakage at the cover joint
• Internal perforation between the exhaust and water passages
• Salt or carbon build-up around the sealing surfaces
• Warped or damaged cover preventing correct gasket sealing
