One cylinder in a Daewoo Leganza may have no compression due to several potential issues, such as a blown head gasket, a damaged piston, or a malfunctioning valve. A blown head gasket can allow coolant or oil to enter the combustion chamber, while damaged pistons can lead to loss of sealing. Additionally, if the intake or exhaust valves are stuck open or damaged, they may prevent proper compression buildup. Conducting a compression test or a leak-down test can help diagnose the specific issue.
