Why white smoke in 4m51 Mitsubishi?

White smoke from a 4M51 Mitsubishi engine typically indicates coolant entering the combustion chamber, often due to a blown head gasket, a cracked cylinder head, or a damaged engine block. This can lead to overheating and potential engine damage if not addressed promptly. It's essential to diagnose the issue and repair it to prevent further complications. Regular maintenance and monitoring can help catch such issues early.
