White smoke out of the tail pipe especially on '''warm''' weather usually means antifreeze/coolant leaking in to the cilynders. you may have a blown head gasket(cheapest to replace) and or a crack/warped cilynder head or crack block(not cheap) if the smoke its happening in '''Cold''' weather it could simply be condensation which is normal.

To find out exactly ,in a v6 engine ,simply take out the 2 middle spark plug (1 of each side) and crank the engine. If you see white smoke come out of either one thats where your leak is and you would go from there.

Note:

Just crank the engine '''Do NOT''' let the engine run for long without sparkplugs or catalyc converter damage may occur.in a 4 cilynder engine take out any center spark plug and see where the leak is

Is it normal for my truck to smoke on a cold day even after truck has fully warmed up? Not thick smoke light white smoke thought it was suppose to stop after truck warmed up fully


white 'smoke' may be condensation (steam)? Did it do this in the summer as well? Even with a warm engine and hot exhaust the steam will still condense after it leaves the tailpipe on cold days. Your fuel contains water at microscopic level which is vaporised as part of the combustion process.

White smoke


White smoke is coolant burning. If the smoke has a blue tint to it that is oil burning. If the smoke has a grey tint that is excess fuel. Any way you look at it, I think a trip to your local garage is in order for an accurate diagnosis.

Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Keep us updated.

I have a 1997 pontiac bonneville, it's running really rich (white smoke out of the tailpipe lightly) dies when it's at an idle. Changed the coil pack, no change.


If it is running really rich the color of the smoke out of the tailpipe would be dark grey or black. Some white smoke out of the tailpipe is normal in cooler weather until the vehicle engine warms up. Otherwise white smoke may be an indication of the engine burning coolant (cracked head, headgasket etc). I would take it to an auto parts store and have them scan the car's computer for codes. This is usually a free service. A code may be present even if the engine checklight is not on. A trouble code will make it easier to determine what is the cause of your problem. There are numerous things that can cause the problem you are having. Also knowing the mileage of the vehicle will help. Sorry that I am unable to help you more at this time.
