TOYOTA LAND CRUISER - 2.8 AUTO DIESEL - SMOKING HEAVILY - WHITE SMOKE

Hello, This means it i time to check the engine oil for a milky substance on the dipstick. Also, you can check the engine coolant with a combustion gas test kit from most auto parts stores. I suspect you have coolant leaking into the combustion chamber. If this vehicle uses coolant to cool a turbo, it may be a bad turbocharger as well.
