Blue smoke is oil being burned in the cylinders. It could be valves not seating properly, valve stem seals bad, possibly a head gasket if it blew where an oil passage may let oil in cylinders, or badly worn piston rings.
If you can afford it, have a shop do a leak-down test of each cylinder to pinpoint the problem. Then you may know if you need a new head gasket, or a valve problem fixed when head is off, or new valve stem seals replaced, or if rings are bad requiring engine overhaul.

SOURCE: transmission fluid going through engine.

It very hard to give an accurate diagnosis of the problem if you don't state at least the year of the vehicle because technology on cars change every couple of years, and a component that is on a vehicle this year, might not be on that model next year.
Here's a guess: if your truck is an older model, then it has a vacuum modulator on the side of the transmission. Often when these modulators go bad, the internal rubber diaphram ruptures and allows the engine to **** up transmission fluid.

SOURCE: engine burning rich white smoke out of tailpipe

White smoke means water, probably a blown head gasket. Pull the plugs and check them.

SOURCE: white smoke when reved up

White smoke on startup could be a head gasket leak between the water jacket and the cylinder. Won't always show in the oil. Antifreeze makes it smell oily or sweet. Compression test will tell for sure. Bluish is oil that was burned. White is usually water or oil into exhaust after combustion.

Van is smoking blue from the tailpipe no oil on the plugs no oil either real bad miss do that sound like heads gaster is gone


Well blue smoke is almost always oil burning.
It could be rings allowing pressure into the crankcase or valve guides allowing oil to leak into the cylinders. Most of the time a leaking head gasket causes problems with the cooling system.
The engine can burn oil and not show oily spark plugs for a long time.

I ran my chev. 1990 pickup out of oil and now it smokes so bad. and i think my fuel pump is going out but not sure??


Sounds like you may have ruined the piston rings and this is allowing oil to seep in to the combustion chamber hence your smoke. Or if it overheated when you ran out of oil it is possible that you have a bad head gasket now. Check both your coolant and oil for signs, oil will have a white froth, or darkening of your coolant. Hope that helps you.

1999 saturn sw has blue smoke coming from tailpipe. I would like to know if it has anything to do with head gasket


blue smoke is usually oil burning- is it light or heavy- if light- change oil and go up one grade- rings are worn- if heavy- time for a rebuild- rings need to be replaced. but for the money on rebuild- could find car newer and lower milage

Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Keep us updated.

I have a 1990 ford ranger xlt that blows out smoke from tailpipe its white with blue in it the mass airflow sensor doesnt do anything when un plugged it has a miss to its a 2.3 liter engine


Sounds like you have a blown head gasket - white smoke = coolant. Pull plugs and look for "steam cleaned plug" or for coolant in oil - looks milky.

Black smoke from exhaust


hi nishga
im dave; hope i can help

First you need to determine if it is actually black smoke or if it is blue smoke. There are three colors of smoke that can come from the tailpipe. It is not white smoke obviously because that is easily differentiated from blue or black and generally indicates water or antifreeze leaking past the head gasket and into the compression area of the motor. White smoke is the steam of the water/antifreeze being emitted

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles. The car has many seals, gaskets, and o-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plugs, it will cause a misfire(engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Black smoke is caused by excess fuel that has entered the cylinder area and cannot be completely burned. Another term for excess fuel is "running rich". Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a heavy fuel odour in the engine compartment. Some of the causes of excess fuel are a carburetor that is out of adjustment which is not likely unless you have installed an aftermarket carburated system on your non-carburated car, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or emissions sensor. If black smoke is present, check the engine oil to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Check the above mentioned systems and after detecting the trouble replace the faulty parts and then the engine oil and filter.
