What causes white smoke to come from tailpipe of Toyota celica?

White smoke from the tailpipe of a Toyota Celica typically indicates that coolant is entering the engine's combustion chamber, often due to a blown head gasket, a cracked engine block, or a damaged cylinder head. This can lead to overheating and potential engine damage if not addressed promptly. It's important to diagnose the issue quickly to prevent further complications. Checking coolant levels and inspecting for leaks can help identify the source of the problem.
