Is it black? black smoke means you are burning too much gasoline could be a bad choke or even a dirty air filter.
Blue smoke means you are burning oil out of your engine
.White means water getting into crank case or pistons.

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 From Tail Pipe/Exhaust

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings

SOURCE: When I start my 2003 ES300 smoke comes out the exhaust

The same thing happened to my 2003 ES300 - the smoke is coming from the oil seeping into the motor's cylinders. This is the classic "Oil Gelling" problem in Toyota and Lexus vehicles. There is a factory recall on it, but it only covers to 2002 ES300 not 2003. The Lexus dealer confirmed my "oil gel" problem and went to bat for me with Lexus - they got the repair approved - Thank you Mr Local Lexus Dealer! The cost was nearly $4,000 - paid for by Lexus.

SOURCE: overfilled engine oil on a

The oil was overfilled this could cause a large amount of oil to enter the exaust and possibly the intake depending on crank case ventilation conditions. If you are positive engine oil levels are adjusted perfectly(warm engine check level running for dry sump oil level ect.). Time is needed to burn off oil residue in exhaust system and intake. Warm up engine low rpm no load, drive vehicle slow with little boost over 5 mins slowly raise rpms for another 5 mins keep driving smoke will burn off while making other drivers mad. sorry just smile and wave.
The engine oil on this vehicle should only be changed by an experinced tech.

1996 Saturn sl2 smoke problem not head gasket no antifreeze seeping in valve cover gasket leaks and losing about a quart and a half of oil no blue smoke kinda white but heavy a little stops driving


White coming out the tail pipes is coolant/water. Doesn't mean the head gasket is blown, but you'll wish it was. Could be a cracked head. They can crack inside the intake or exhaust port. This would still give you a good compression reading. If in the intake, you would have a misfire. Exhaust you wouldn't. As far as the blue goes. It is mostly white in color, with a hint of blue color. Loosing that much oil would be a major leak or the rings are shot. Rings being shot, you would see that blueish tint in the smoke.

What causes white smoke to come from the tail pipe with strong fumes while in idle?


A heavy presence of white smoke from the tail pipe is usually caused by a bad headgasket. If this gasket is bad, the vehicle may run rough as well as overheat.

Smoke coming from engine


Where is the white smoke coming from? Under hood? Out tail pipe? If excessive white smoke from tail pipe, suspect a head gasket failure which in turn will fill the cooling system with exhaust pressure forcing the coolant to come out of the reservoir and resulting in an overheating problem

When I start my car smoke comes out of tail pipe for a few seconds water all so coming out


Water and vapor (steam) coming from the tail pipe is normal and will stop after a few miles when everything is hot. That is one of the reasons exhausts need replacing as they rot with rust and is more evident on cars that only do low mileage as the exhaust does not get hot enough to boil off the water and it sits in the pipe slowly rusting it away. What you see as smoke is probably steam and is more evident on cold mornings. If the car is not using oil then I wouldn't worry.

White smoke out of exhaust


Regarding 2001 audi a6 quattro 2.7t....i was driving to work the car was fine then white smoke starting coming from under the hood and tail pipe. i stopped veilce and alot of oil was dripping from front of car. I towed it home and i looked under the hood and there was oil from valve cover gasket. i let the car sit for a few days, had it running again for a good hour and no white smoke was coming out. I removed the valve cover and gaskets are all bad. i want to know can the valve cover gasket leak cause the white smoke to come from exhaust pipe?

My 98 firebird tail pipe blows white smoke and water out the tail pipe then as i let it sit for 30 minutes the engine gets hotter then gas like smile and heavier smoke come out the tail pipe it also s


One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
