Why is thick white smoke coming from your Mazda RX8 exhaust?

Thick white smoke from your Mazda RX-8's exhaust could indicate coolant entering the combustion chamber, often due to a blown head gasket or a cracked engine block. This can lead to serious engine damage if not addressed promptly. Additionally, it may suggest issues with the apex seals, which can cause oil to leak into the combustion chamber. It's advisable to have the vehicle inspected by a mechanic to diagnose and resolve the issue.
