Sounds like a blown head gasket. if it lacks power, misfires or perculates in the overflow jug (sounds like a coffee maker brewing) after it reaches operating temp when you cut the vehicle off,then its a blown cylinder head gasket.

SOURCE: car is hard to start, keeps stalling, white smoke coming out of tail pipe

It sounds to me like you have a head gasket leaking. See if you can get a gauge and check each cylinder. Are you using alot of anti freeze?

Too late to check now... you've got a blown head gasket. When the gauge starts to give you any indication that something's not right you must shut it down or this kind of thing happens. Could have started as a bad water pump, hose etc. With low coolant from that (or anything else) continued operation will kill the whole thing!...Sorry!!

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;

Head gasket failure or a crack in the cylinder head allowing engine coolant to enter the combudtion chamber, then out of the exhaust.

SOURCE: my car has white smoke

If the white smoke comes out when the engine is warm, then you have a head gasket leaking. Give the warm exhaust a smell, if it is a sweet smell then you deffinitly have a head gasket leak. Pull the dip stick out and check to see if there is any foam/ frothing on the dip stick. This will tell you if the coolant is leaking into the oil passages and if it is, do not drive the car. The coolant will wash your rod and main bearings causing the rotating assembly to fail. The proper fix is to replace the head gasket and have the head checked for warpage. Do not use coolant system repair compounds as they will plug your heater core and now you have that to replace also. I hope this helps.

My car has white smoke coming from the exhaust


he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
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.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

When the vacuum modulator goes, the engine vacuum draws ****** fluid into the combustion, causing white smoke. It is located on the side of the ******, circular in shape, with a vacuum hose connected to it.

What is causing white smoke coming out of the mufflers when I start the engine?


It's normal for a thin white smoke to come out of the exhaust at initial start up. This is caused from moisture built up in the exhaust burning off. However if there is a continuous flow of thick white smoke it could be a blown head gasket causing coolant to burn.

White smoke coming out of the exhaust when starting the engine?


Its the problem of oil.The oil is getting burned out. The vehicle is either burning oil or it is moisture in the gas chamber if you notice white smoke from the exhaust. This is a common possibility.but in some cases this white smoke is not due to oil burning.In that case   White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Normally this is a sign of a blown head gasket or cracked head. And  this is not a common problem must be repaired immediately. You must STOP driving this vehicle or you will cause serious engine damage. you will have to get both this possibilities checked.

Hi, what does it mean when huge amounts of white smoke comes out of the exhaust? otherwise drives ok? it is a renault megane 1.5 dci 2004. regards catherine


Symptom: White smoke or water vapor from the exhaust. You notice white smoke coming from the exhaust when you start your car. If it is cold out, this may be normal. If the smoke does not disappear after the car is warmed, you have a problem. Possible causes:
  1. Transmission fluid may be entering the intake manifold through vacuum modulator.
    The Fix: Replace vacuum modulator
  2. Cylinder head gasket(s) may be bad.
    The Fix: Replace cylinder head gasket(s).
  3. Cylinder head(s) may be warped or cracked.
    The Fix: Resurface or replace cylinder heads. (Resurfacing is not a DIY job)
  4. The engine block may be cracked.
    The Fix: Replace engine block.
