I agree with red_blazer, but just in case, it could be more serious. Have the head gasket checked and replaced if needed.

Is it cold where you live because if it is then this is perfectly normal cars need to warm up once the car warms up a little bit it should go away its kinda like how u can see your breath when it is cold out because your car produces water vapors you will be able to see it on most cold mornings

97 es 300 car runs great stopped at store 30 min when restarted heavy white smoke


White smoke means water is getting into the engine from teh coolant system. Likely that your engine cylinder head has a crack, or head gasket is bad

330d sport smoking and overheating.......help


You pay be burning antifreeze. You may have headgasket leak. Have compression tested. If you see white smoke, you may very well be burning up the coolant.

My 99 cougar smokes


You have to determine why it is smoking and what the smoke means. White smoke almost always means you have coolant entering the combustion chamber. The exhaust will smell sweet. I am not referring to the white smoke you see when it is cold and stops after awhile, as that is condensation. I am talking about white smoke you see when it is not cold. Stop driving the car immediately or you will have serious engine damage.
Black smoke is the result of an overly rich fuel/air mixture and can be caused by many things.
Blue smoke is an indication the engine is burning oil. Normally caused by worn piston rings.

Heap of white smoke on startup but not always


White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather until the engine warms up.

Faulty glow plugs or control module can cause white smoke on engine start up.

Low engine cranking speed may also produce white smoke.

If white smoke is still visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing or a worn injection pump.

Low compression or air in the fuel system can also be a source of white smoke.

White smoke from the exhaust when I start the car


Hi!

What type of smoke can you see---

white smoke-
If you see a wispy, lingering white smoke that has a bittersweet smell, this is an indication that your car's engine coolant is leaking into the combustion chambers. This may be due to a leaky head gasket, or in a worst case scenario, a cracked cylinder head.

Make sure to take your car to the shop right away to get it fixed.
Thick white smoke---
If your vehicle is belching white smoke upon start-up, it is a sign that transmission fluid is entering the combustion chambers, possibly though a vacuum tube that connects the engine to the transmission.
This type of smoke can be confused with the normal puff of steam during start-up. If you are not sure, have your car inspected at the shop.

Blue/White Smoke--
A blue/white smoke is an indication that oil is being sucked into the combustion chambers through the valve guides. A quick fix for this problem is by replacing the valve seals. Valve seals are small, umbrella shaped pieces of rubber.

Do rate the solution.

Thanks
Rylee.
