If the smoke is truely white, then I would be looking for a cause of coolant burning in the cylinders. A bad head gasket, cracked head, or block could all cause this. See if your coolant level is low after cool down. If the smoke is a light blue (almost white) then I would look for reasons the engine is burning oil. If your oil level is constantly low without leaks then it is likely you have an issue with piston rings, valve seals, cylinder wear, oil intrusion into pcv system, or some other problem allowing oil into the cylinders.

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.

Car spews a lot of white smoke i assume its steam from coolant or antifreeze from a cracked head gasket,was told it needed spark wires and plugs and brakes,


no you cannot judge on that before checking what the problem is
have you checked what how the is oil level in because when the smoke is white that means it is oil
if it is black that is gaz .accordingly you have an oil leak from valves where the upstroke forces oil into combustion chamber where it is burned and causes white smoking

I have a 1991 acura legend and it blow a lot of smoke from exaust what could be causing this and how to fix the problem

My smoke comes through my pipe


Well, it's the type of smoke that really matters. Does it smoke black? Blue? White? White for the first ~2 miles/5 minutes of warm up is not a bad thing, just blowing out condensation. White smoke that never stops is a sign your head is warped/head gasket is busted. Blue smoke is a sign that you're burning oil bad. Black smoke indicates an overly rich fuel condition.

White smoke from tailpipe and low oil pressure


How's the anti-freeze doing? Usually when you see white smoke coming out the tailpipe it's because you are getting anti-freeze in the exhaust somehow. Try to sniff it a little does smell like anti-freeze, or oil? I don't know why the oil pressure would be low unless you are getting anti-freeze in the oil. Does the oil look milky, knda like chocolate milk? The low oil pressure could also be a faulty gauge, you may want to have a mechanic put a mechanical gauge on the car for test purposes.

My 1995 Acura Legend smokes very bad when at an idle. If I replace all the gaskets and the rings, will this most likely fix the problem? I have someone who will do this for me. I do not have the money to...


you think all gaskets and rings will cover everything? 1st thing you must do is determine the source of the smoke. If it only smokes at idle, but never under accel or at cruise, I would HIGHLY doubt its rings. Rings leak worst under pressure...when accelerating or under high load. If it smokes at idle and even more under long decels (like coasting down a long hill) it may very well be valve seals. If it ONLY smokes at idle and never any other time, it may be as simple as plugged oil returns or a PCV problem? Dont start changing things. DIAGNOSE 1st, then change when you have determined a cause.

1998 leganza motor smokes when it warms up


If the smoke is white, or steam it is water. you might have cracked the head or warped it. Did you get it looked at before you put the new gasket on? If the smoke is black then it is oil. Do a compression check and see if you don't have a bad cylinder. They should all be about the same give or take 5 lbs.

White "smoke" spewing from my Kia.


Check your oil, you may have a blown head gasket. Check the oil too see if it has antifreeze in it
