SOURCE: coolant leak/head gasket

it is possible that the higher rpm is creating more pressure in the cooling system and forcing the antifreeze into the cylinder, if you know how, do a compression test on the engine and observe the plugs as you pull them for moisture..............however i am thinking that you may have to wait until the problem with the smoke gets worse in order to determine which cylinder is leaking

Your thermostat may have been installed upside down. Very common mistake. Was your vehicle running before the maintenance was done?

SOURCE: white smoke from exhaust

Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
Thanks;

Unfortunately this sounds like your head gasket has failed. You will need to replace this soon or risk serious damage to your engine.

You may have a leaky head gasket. Have a mechanic do a compression test.

04 chevy impala has white smoke coming from the exhaust but no leaking


white smoke is caused by water or coolant entering cylinders, if in over flow it will look like a chocolate milk shake. check on oil dipstick to see if you can see traces of water or anti - freeze in the oil. if you see white smoke coming from tail pipe that smoke means that your car has a leaking cylinder-head gasket or a cracked head gasket. If there is just a leak in the gasket, the problem should be relatively easy and inexpensive to fix, but if the problem is a cracked head gasket, chances are the repair will be a lot more complicated and expensive. If the problem is a leaking head-gasket cylinder you will see white smoke, because the faulty gasket is allowing air and fuel to enter the cooling system. As this mixture burns, white smoke is produced and exits through your tailpipe. If you are familiar with the location of the cylinder head gasket you can check it yourself, otherwise take the car to your mechanic and ask him to check the gasket for damage. may not be but just check it out! if its water or anti-freeze, you will smell a sweet smell coming from tailpipe. good-day ! most of the costs today are labor which is very expensive.

I have a 1995 chevy astro van that throws out gray smoke from the exhaust which later turns to black smoke the smoke also smells like gas


May be a head gasket. Anti-freeze will burn white / gray. Make sure you are not losing coolant. Look at your oil on the dip for any signs of foaming / water.
Take care.

I have a 1994 chevy s-10 blazer vin w with a 4.3 l vortech its white smoking with loss of power and is missing very bad


white smoke is caused by coolant mixing into your combustion camber which is burning through your exhaust. More than likely a leaking head gasket is at fault

My 93 maxima got no power an smoke started to come out the tail end.


The best test is a compression test.
Blue smoke means it's burning oil, due to worn out piston rings.
White smoke means it's mixing antifreeze and oil due to a bad head gasket or cracked head or block.

White smoke coming out tailpipe


If your intake gaskets are leaking, when you dump soapy water on the gasket, it should bubble like crazy ( when it's running). If you can, run it with the rad cap off and watch for bubbles. If it keeps bubbling, you probably have a head gasket problem.
