SOURCE: mazda bravo blowing white smoke

blowing white smoke is almost always a symptom of an engine coolant leak at the cylinder head gasket. remove each spark plug and look for a dis-colored plug to find which cylinder is leaking.

SOURCE: White smoke exhaust

White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....

SOURCE: White Smoke From Tail Pipe/Exhaust

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings

SOURCE: My isuzu 4JA1 engine tends to exhaust white smoke

White smoke means that you have a coolant leak. Two possible causes for that - either the head gasket is punctured and must be replaced or the head itself is damaged and must be welded by an expert. 
Either way the engine must be dismantled to make a full diagnose and repair.

Engine was knocking but running good not smoking so we replaced the engine with brand new short block from Toyota. Now the truck is blowing white smoke. What could the tech done wrong to cause this? Or...


Take it back. I doubt the short block is bad, but if the smoke persists beyond a day or two, the cylinder head may need removing to check the fit of the head gasket, and to ensure the passages in the head match the block. Does the exhaust have a sweet smell? That could be coolant burning.

Now it is possible that a little spilled coolant may have collected in the exhaust during the engine swap, and that is why you see white smoke. This should burn off in a day or two. If the smoke persists, and the coolant level is dropping, they need to take it back and fix it, at their expense, at least the labor charge. Toyota may have made production changes during the year on this engine, and that is what needs to be investigated. That, and if the head gasket is correctly fitted.

I'm looking to purchase a used car. I've been doing online research and saw this webpage http://www.usedcarsmells.com . They talk about exhaust color and smells. Is it true that you could tell a lot about...


Yes this is correct, you can get important information from the colour of smoke from the exhaust:

Blue/Gray Smoke: Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber. These are possible symptoms and causes:
Valve Seals: Leaking valve seals will cause blue/gray smoke at startup because oil leaks past the seals into the cylinder after the engine shuts down.
Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder.
Piston Rings: Worn or damaged piston rings will cause blow-by resulting in blue/gray smoke.
Worn Cylinder Walls: Worn cylinder walls cause blow-by resulting in blue/gray smoke.
PCV System: A stuck closed PCV valve will cause excessive crankcase pressure resulting in blue/gray smoke.
Black Smoke: Black exhaust smoke is an indication of a rich fuel condition. These are possible causes:
Fuel Injectors: A leaking or dripping fuel injector will cause a rich fuel condition.
Fuel Pressure Regulator: A stuck closed fuel pressure regulator will cause a rich fuel condition.
Fuel Return: A restricted fuel return line will cause a rich fuel condition.
White/Gray Smoke: White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes:
Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber.
Engine Block: A crack in the deck of an engine block near the coolant jacket will cause coolant to enter the combustion chamber.
Head Gasket: A damaged or blown head gasket will cause coolant to enter the combustion chamber resulting in white/gray smoke coming from the tailpipe.

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?

Motor is smoking in my '02 diamante, is it the gasket?


Smoke diagnostic is made by colour.
If u mean pistons head gasket,yes,it can smoke.
White (clear) water vapor.Ceck coolant level.Ceck engine oil colour by dipstick.

Black:runs rech on fuel (fuel filter/fuel lines/fuel mixture...)
Blue (whity):worn pistons rings.

Chears.
Tips:
Whity smoke before warming may be natural on cilli mornings with lot of compressure the engines just blows vapors.
Old oil/fuel residues in the exhaust tubing may blow smoke after heating the engine ,must track problem (...).
Black smoke on hitting the acceleration to the floor may be natural (overcharged) avoid sport driving style.

Smoke coming from exhaust in 1997 Saturn SL sedan


What is wrong is you bought a worn out motor
with 147,000 miles
White Smoke is usually a bad head gasket
In your case it sounds like a really rich fuel condition
where you spit out a lot of fuel on start up.
I won't go into how to diagnose the many issue it
may have,it would take too long & unless you say you
have experience then only a repair shop would be your
answer to at least diagnose the issues
Just think about the cost question
Your on the internet talking or asking people
all over the world with different currency to answer
your question
You also have no idea what is wrong,so no dealer or
shop would know what the end cost will be.
There are no set prices from one shop to the next,
for anything & for good reason.
Your in charge of the education process,asking questions,
& authorizing whatever you choice to do with the car & it's
problems
