    This truck blows a lot of smoke while it is running. it will eventually choke itself out. We think its the turbo it has a loss of power and is using a lot of oil. also it has oil in the antifreeze but not the other way around. it is a cat c-13 engine

    What year make and model is the engine? What is the color of the smoke? Did you do a bottle test on the cooling system? There are going to be some extremely knowledgable people that will be chiming in and will help a lot, but there is a lot of testing to be done to pinpoint what your issue is. My very amature opionion is that may not be the turbo.

    Haven't done a bottle test yet. The smoke is white. It's a 2005 Kenworth t800 with the c 13 dual turbo Caterpillar engine

    So using a lot of oil, putting oil in the coolant, white smoke and down on power. Does the smoke smell sweet? Im guessing that you may have a ruptured oil cooler or blown head gasket. Is it using coolant too?

    And when you say choke itself out what are you referring to?? Like the engine dies? Or does the white smoke go away?

    White smoke is usually water or coolant.Black is fuel, blue is oil.

    The smoke does smell sweet. It is not using coolant and the engine is loud and dies after 5-10 min.

    Sweet smelling smoke thats white is a 90% sign that it's burning coolant. And somewhere where coolant and oil are side by side there is a seal broken. The oil is displacing the coolant so that is probably why it doesn't appear to be using coolant.
