SOURCE: white smoke?

It's just condensation. Water will also drip from the pipe.

The colder it is, the worse the 'smoke' will be. I was in Vernal, Utah earlier this week, drove through -18*F weather, my truck never quit blowing white smoke.

And NO IT IS NOT YOUR HEADGASKET

SOURCE: white smoke comes out tail pipe

Its perfectly normal.Hot exhaust gases mixing with cold air and by products of the combustion process create the watery substance that you see spit out .Dual fuel (LPG,Hydrogen etc) vehicles do this a lot more noticably.By products of the combustion process are various but water vapour is one of them.Alot of heat is generated by the exhaust so watching a car driving in very cold conditions you can see this effect more clearly

SOURCE: white smoke coming from exaust while the car is hesitating

If you have white smoke coming from the cars exhaust this would indicate your engine is getting coolant in to the cylinder(s). This could be a bad head gasket, cracked or warped head. Sorry to say but your engine sounds as if it may need some big $$ work to be done to it. If you have the skills or a friend who does have a compression check done on all of the cylinders to help locate where the issue is at. Another way of check , with the engine cold, remove the radiator cap and start the engine if you see bubble in the radiator fluid this is air being pumped in to your cooling system by a cylinder or two. I wish I could bring you better news but the information you had shared you'll need to make a decision of whats your best course; repair or replace. If your confident you can do this repair over a weekend, otherwise this repair can get pricey.
Best of regards,
Tom

SOURCE: Upon starting avalanche blue, white smoke comes

Take that truck into the dealer and have them repair it under the powertrain warranty. 2007 offered a 5 year/100,000 mile warranty.

The smoke on startup is the result of oil getting past the valves.

My 01 gmc jimmy made a loud pop and white smoke started blowing out from under the hood. Now it makes a knocking sound but not like its low on oil or inside the motor. I dont have water in my oil and now...


The smoke under hood means that u need replace gasket between exhaust pipe and engine but smoke and knocking is not very good, it looks like your engine pistons has cracks and u r loosing oil by smoke time to time, i'd buy used engine from crashed car with less miles on it

My 1991 honda accord fails to start after I have driven it a short distance and turn it off. I also is blowing white smoke out of the tail pipe


If it is a constant smoke and or alot, your head gasket is blown. stop driving it if you want to save this engine. also engines with really high miles don't like head jobs, remanned heads can blow out the rings on the pistons and that leads to an engine rebuild. If your car has really high miles , you would be better off replacing the engine

White smoke occasionally coming out of my Altima tail pipes.


If there is no loss of Coolant, which is a sign of Head gasket failure to the combustion area, which generates white smoke, I would recommend after 4000 miles of your mileage alone, a complete Service of Engine Oil and filter, AIR filter and Fuel filter.
An inexpensive way to find a recurring combustion problem, At 60k miles, the Spark plugs should still be good, but pull them anyway, just to confirm.

Alot of white smoke is coming out the exaust pipe


Ouch!
White smoke means water (steam) in the engine cylinders, coming from the cooling system....
broken head gasket or cracked cylinder wall.

1998 - you might want to temporarily use an engine sealer. AutoZone can advise which is best for plugging a head gasket leak.
It will need to be replaced ($200+) and get valve job done ($100) at an ato parts store that has a machine shop, since the valve head must be removed to replace the gasket between thr head and the engine block.

Not likely, but it could be water in your gas tank. Did you just fill up?
or was the car driven with an over-heated engine?

Look at the opil dipstick. There will be a milky substance in the oil. That's water mixed with oil.

White smoke coming from my tail pipe when I accelerate


You may have a blown piston ring, valve seals, valve guides, cracked head gasket or a cracked block, etc... It sounds major though for you to lose power suddenly and have all that smoke...

I have a 1999 saab 9-5 model and i have 195.000 miles on it i went with the 0 weight 30 mobil one synthetic motor oil on my oil change ran it 3,000 miles and just as i was about to change the oil again it...


Sounds like it's time for a compression check. The head or gasket could be blown, and this test will confirm or deny this fact. Your smoke/steam and the oily residue are pretty good clues...accordianman
