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

My 1998 Mazda millenia Is shorting white smoke more tell pipe what could be the problem


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. THESE LEAKS WILL CAUSE SEVERE ENGINE DAMAGE! Have the car inspected immediately.

White smoke from exhaust


The white smoke you are seeing is steam. From your description, sounds like you have coolent seeping into the combustion chamber, mixing with your fuel/air, and exiting out through your exhaust as steam. 1, blown head gasket. 2. cracked head or block, 3, warped head due to overheating. Most common is #1.

white smoke from the exhaust and overheating would almost certainly mean a blown head gasket.
the head gasket has gone between a cylinder and a cooling channel so exhaust gasses can get in to the cooling system resulting in the boiling and water from the cooling system is getting into the cylinder resulting in the white smoke (actually steam) from the exhaust.
the exhaust manifold is a separate issue that can be replaced when the head gasket is repaired.

I have a 1997 bmw 528i and its constantly overheating also theres a lot of thick white smoke that coming from the tail pipe. What could the problem be?


Unfortunately, you are experiencing two of the classic signs of a bad head gasket. Have the coolant checked with a test kit from your favorite auto parts store to verify this. I would check the radiator coolant regularly to verify coolant loss. Sometimes engine cooling system designs can allow for a bad hose to come in contact with the exhaust and make smoke out of the tail pipe so have all of the hoses checked too.
Hope this helps.

white smoke usually means blown head gaskets,have radiator fan checked,water pump,check coolant for oil in coolant,could be blown in between cylinders,causing coolant to go out exhaust,have compression check done on cylinders.

There is NO way water can get inside the muffler / exhaust pipe without evaporating, and causing a white smoke at the tailpipe. Additionally, in order to get inside, you would get major power and idling problems. I would look at the cooling circuits near the firewall ( cooling hoses to the internal heater, for example) because one of them must be dripping water externally onto the exhaust pipe or muffler. If the car never overheats, there is a possibility that you are simply overfilling the cooling water bottle. The full mark for accord bottles, is waaay down, it looks as if the bottle was empty. As soon as the engine heats up, it will send excess water overboard.
