Reason for replacing cylinder gasket 997-108 The reason for replacing the cylinder head gasket 997-108 is due to damage caused by excessive heat, pressure, or wear and tear on the engine. The cylinder head gasket seals the combustion chamber, controlling compression and preventing coolant and oil from leaking into the cylinders. When the gasket fails, it can cause engine misfires, reduced power, overheating, or even complete engine failure. Regular maintenance and inspection can help prevent these issues, but if damage is detected, replacing the cylinder head gasket is necessary to restore engine performance and prevent further damage.   Part Number:997-108 Part Type:Cylinder Head Gasket Brand:FG Wilson Attributes(H/W/L)cm:1.00/34.00/85.00 OEM Alternative Part Number:FG Wilson 997108 Compatibility:Perkins 1306.FG Wilson P250H-3 P275H-3.   997-108 Picture show
