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?

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.

Van used 2.5 quarts of oil in 1200miles no sign of oil burning or blue smoke at tail pipe. oil light comes on frequently 2004 dodge caravan


If there is no sign of oil consumption, then you have a leak some where. Un-noticed leaks are usually found at the rear main seal and leak as you are driving. If you crawl under the vehicle and closely inspect the area where the engine block meets the transmission you may find evidence of an oil leak.

When I start up, a lot of white smoke coming out of the tail pipe. First occurrence was this morning. Is it safe to drive to the car repair shop, or should I have it towed? And what do you think is the...


HI. This will be the cause of coolant consumption that is occurring at this time. I will list the most common culprits below.

Coolant consumption::: Possible causes______


1. Check the head gaskets. The gasket may be leaking, thus allowing coolant to leak into the combustion chambers.

2. Check The Intake Manifold Gasket. This gasket may be leaking, worn, or damaged

3. Check the cylinder head for worn or scorn cylinder block.(This will require total breakdown of the engine)

4. Check the water pump seal for leaks as well.

Now that we have covered the basic check points for coolant consumption, i would advise to concentrate on the head gaskets if there are no apparent leaks on or around the engine itself. If the head gaskets are worn, the leak can be introduced to the engine internally, causing the engine to burn off the coolant. this is noticeable by removing the oil cap, after a hard drive. you Will notice steam that will escape the head as soon as you remove the cap. If this is the case, your problem will be with a failed head gasket.

IN a severe case, you will notice white plums of smoke escaping from the tail pipe during acceleration

Losing coolant but not leaking


If you are absolutely certain that there isn't any external leaks then it has to be burning it. You may have a head gasket that is leaking slight enough that over time you notice a loss of coolant but it may not leak bad enough to notice it steaming out the tail pipe. Make sure that you do not have an intake manifold leak that just isn't hitting the ground. That is the first place I look for antifreeze leaks on GM engines(If thats all you been looking for is any fluid on the ground beneath where your car sits)

Leaking oil put of tail pipe, is the cooling sensor important, head gasket blown how do you know


Never seen oil come from tail pipe (unless a piston has a broken ring or a hole burned in it.) Cooling sensor tells the computer the engine temp and the computer turns the fan on through the fan relay. Very important for it to work. A blown head gasket will make the engine overheat, can cause white smoke from tailpipe, coolant loss and extremely rough running. Also can cause coolant in engine oil or oil in radiator. What you may be seeing may be water mixed with carbon from the inside of the pipe. Excessive water coming form pipe is also a head gasket symptom. A compression test or cylinder leakdown test or a radiator hydrocarbon test will tell you if gasket has failed.

when coolant gets into a cylinder it will eather keep the plug from firing or the plug will fire and the coolant will become steam (lots of it ) out the tail pipe and will smell sweet. if this is happening it is a head gasket problem.
