Water vapor is a normal by product of the combustion process.
there is no water mixed with the oil but have antifreeze coming out of the exhaust
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.
Internal engine antifreeze leak what else could cause besides headgasket? there is no antifreeze in the oil it is clean
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.
Head gasket or cracked head. Mo
Blown head gasket.
Answerwhile the engine is running, the exhaust will have a sweet smell, the exhaust will also be extremely dense and alot of it. In extreme cases there is a possibility of antifreeze in the oil pan. Checked by pulling dipstick, the antifreeze will appear blotted on the oil.
catalytic converter converts some oxides to water, so water not a surprise in and of itself. Is there Antifreeze in your exhaust moisture? are you sure it is antifreeze? are you loosing coolant reservoir level at a measurable rate? Coolant only gets into exhaust by way of the cylinder head developing a leak. from the cooling jacket into the exhaust port of a cylinder. if it was leaking into the combustion chamber, you would have coolant in your oil, and the plug would be fouled with scale. possible to attempt a leak seal with K&N Metal Block Seal, if and ONLY if the leak is NOT into a combustion chamber. Or do the right thing and get the head repaired. Or, have your intake gaskets checked for leaks. On the 3.4 the intake gasket can leak coolant into the engine.
