I agree it sounds like a coolant leak into the combustion chamber from the steam coming from the exhaust. You can purchase a kit to check for exhaust gas in the cooling system that takes just a few minutes to do. Also a compression test can also indicate which cylinder the problem is in if the leak is into the combustion chamber.

White smoke usually is coolant burning. Is engine loosing coolant? Small pop could have been head cracking, or possibly head gasket failing. If you are loosing coolant, time to remove the head to see what failed.

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.

Why bmw x5 battery drain fan not working exhaust blowing out white smoke... what may be happening.


White smoke out of the exhaust indicates moisture (water) in the exhaust. If the car is not driven very far each day, some moisture will collect in the muffler and cause white smoke for a short while after starting. If the smoke is continual, however, you need to watch you coolant level as you may have a blown head gasket.

Blowing white smoke out of exhaust pipe


White smoke is usually a sign for a bad head gasket. How much white smoke is coming out? Also, are you losing coolant and can't find a drip under the engine?

My daughter's 2003 Oldsmobile Alero was blowing white smoke from exhaust. She said that it was a bit sluggish when accelerating. I started it when I got home this evening and it blew white exhaust so I hit...


white smoke is normaly an indication of water entering the combustion chamber of your engine due to a broken head gasket. I am surprised that it stoped but I think that the probelm will come back.

Blueish white smoke comeing from exhaust


Hello There

White smoke when first started is normal. If white smoke continues you have an internal coolant leak, i.e., cracked head/blown head gasket.
Black smoke is caused by a rich fuel condition.
Blue smoke is caused by oil consumption.

You need to check your oil cap for yellow/white gunk on the cap if you have this then this is a sign your head gasket is cracked. Check to see if your radiator coolant level is down this is also another sign.

Hope this helps. Please don't forget to rate me.

Many Thanks

White smoke coming from exhaust when accelerating


This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.
