You possibley have a blown head gasket on the side that is blowing water and steam. 390 s are good solid blocks pull the head on that side and check carefuly to see if you can spot the bypassed gasket. If not a gasket a good idea to have the heads checked for cracks then the engine. Small steps.

could be a blown head gasket on that side, or a bad intake gasket.

The side you see white smoke from has a head gasket or cracked head problem.

If sparkplug has water or rust on it you have located the cyl of question. Is it the Intake manifold or head gasket. Water runing into intake valve would be noticeable when you pull the intake manifold. You might hear knock when motor is hot, that would indicate steam knock from blown head gasket. Piston in question would be steam clean from antifreeze hard blast on ignition................. ........ do a compression test, a week cylinder could indicate not only a blown head gasket but also tell you what cylinder.

How would you know if you have blown head gaskets?

engine burning oil( white or blueish exhaust smoke ), water in oil, oil in water, water in exhaust.

What is the white stuff coming from a teapot called?

That would be steam or water vapor, which is water in air form.

Can a turbo cause excessive steam to pass out of the exhaust?

For steam to come out the exhaust you probably have a bad head gasket or a cracked head. If the turbo had an oil seal fail it would cause blue smoke to come out the exhaust.

Why would what appears to be water be leaking from your muffler?

That's exactly what it is, water. The products of combustion are water and carbon dioxide. While the exhaust stays hot the water comes out as high temperature steam, usually you don't even notice it. When the exhaust pipe and/or outside temperature is cold enough the exhaust will cool and some of the water vapor will condense into steam and possibly even water that drips from a weep hole in the muffler. If you're seeing a little water drip from the muffler, everything is working as designed.

Why is water coming from exhaust on a 1991 Chevrolet Suburban?

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.

Why does your car create steam when you start it?

White smoke (steam) out the exhaust would indicate a bad head gasket or a cracked head or both. If the steam lasts for a few minutes after your start the car and stops, it is probably just condensation. This is normal, especially in cold or wet weather.

What can cause white smoke from exhaust when heater is on?

I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.

You have white smoke coming from your exhaust?

White "smoke" in the exhaust usually means there is moisture in the exhaust stream.If the "smoke" appears while you're driving away shortly after the car is first started on a cold morning it is likely the condensation boiling off the inside of the exhaust pipes (steam). This is normal and goes away as the exhaust warms up. The condensation is also normal; it usually happens after the car is shut off on a cold day and the water vapor in the exhaust gases is allowed to condense as the exhaust system cools down.If you have white smoke all the time, you may be leaking coolant into the cylinders which could mean a head gasket leak. Usually there is oil residue in the exhaust as well, which would be a tell tale sign of a blown head gasket. Then the white smoke would have a hazy blueish tinge to it. Also, certain chemical engine cleaners and fuel additives can create a white smoke. Have a mechanic check it out if necessary.

Would the steam from sea water be salty?

No. The water that evaporates to form steam leaves the salt behind in the oceans. Steam is pure water, always.

What is the name of gaseous water?

That would be, "Water vapor" or "Steam", but not the "steam" that you see coming from a pan of boiling water - that is not steam, but rather, tiny droplets of liquid water.

Is steam an element compound or heterogeneous or a solution?

Steam is water and water is a compound - H2O. So I would say steam is a compound.

If you wanted to change the steam back in to water what would you have to do to the steam?

You need to cool it down.
