White smoke at startup (when the engine and exhaust have completely cooled down) is usually caused by condensation. It's especially noticeable in cooler weather when the car is used for short trips. The engine never really gets totally warmed up, existing condensation in the exhaust isn't completely evaporated. In short, what you may be seeing is simply steam vapor. If the smoke isn't white but is more gray or blue/white it's oil. A few seconds of oil smoke at startup is usually caused by leaking valve stem seals. Oil drips down the valves and onto piston tops when the engine is idle. On startup the oil is burned causing a few seconds of smoke. The puff of burning oil is most noticeable after the car has been sitting awhile, like overnight. Unless the seals are really bad not enough oil drips into the combustion chamber during shorter stops to notice any smoke. Cheers
there is no water mixed with the oil but have antifreeze coming out of the exhaust
it is in the front of the vehicle below the oil filter, exhaust manifold and coils
Nope.
A bad head gasket or a cracked head will do that.
not unless you have a cracked head or blown head gasket
Bad head gasket or... Crack in exhaust port in head. Check exhaust for presence of antifreeze smell or exhaust gas in radiator.
Water vapor is a normal by product of the combustion process.
Internal engine antifreeze leak what else could cause besides headgasket? there is no antifreeze in the oil it is clean
There are many things that could cause your exhaust temperature to be high. Your exhaust may be plugged for example.
Probably - your head gasket is blown. Antifreeze will be coming out of the tail (exhaust) pipe.
That is condensation due to the exhaust system being cold and the heat from the engine makes the exhaust system / pipes sweat. As the exhaust system heats up then that will stop. Now you said WATER not antifreeze. If you had engine coolant running out of the exhaust then it would be the color of the antifreeze and it would be steaming WHITE and then you would have an engine problem, MAYJOR. You said water. Drive it you have no problems. That is normal.
A gm 3.8 l v6 or 3800 cc engine cannot have antifreeze in exhaust without first getting into the engine. If its getting into the exhaust it may be entering the cumbustion chambers through a damaged cylinder head or head gasket. Also this engine depending on the model year may have issues with the intake manifold gasket, that can cause antifreeze to leak into the engine oil.
