My 94 acura integra smokes out from the muffler, why??

Like they said, White Smoke=Blown Head Gasket,other thatn that though, if your coolant is milky there is oil in it. other than that, you need to get a HELMS Manual for your car and fix it but if you dont feel that you are capable, definatly take it to a shop because this is not a joking matter

what color is the smoke? What does it smell like? Whats your oil level? what color is your oil and coolant?what type of gas do you normally fill it with?

cars will smoke for numerous reasons. If youre getting a sweet smell from the exhaust, its going to be a coolant issue, If youre getting a rotten egg smell, its going to be spark/fuel/timing/ coolant issue, if youre getting white smoke, its going to be an oil/coolant issue, if youre getting black smoke, its going to be a fuel issue.

start by determining what color or smell the exhaust is.

Then pull the diagnostic codes to see if you have any problems. Pull up the passengers side kick board and look for a small loose wiring harness connector. Its going to be blue/grey/black/green. Stick the end of a paper clip in one hole, then stick the other in the other hole. Now, turn your car to the 'on' position. if you have codes, the check engine light will flash. 'flash' flash 'flash' pause 'flash' is code 31

next, check the coolant. If you have brown oily coolant, thats not a good sign. It could be a broken head gasket, or more serious, a cracked head (which would require basically a new engine).

If you have brown chunks in the coolant, this is much easier to fix. Youre basically going to have to flush the coolant system. The easiest way is to use a garden hose.

while youre flushing the system, check the thermostat. boil some water then stick the thermostat in it. if the thermostat doesnt do anything, replace it, if it opens, its fine.

check the oil. If its creamy, its going to be one of the previous problems.

if the oil is fine, and the coolant is fine, the next thing you want to do is flush the oil system. Buy a gallon or so of kerosene, drain your oil, change the filter, pour the kerosene in the oil cap (the amount of oil youre car will normally take), start the car and run for 20 seconds. Shut it off, drain the kerosene, then fill the car with oil, run for a few minutes, then drain the oil, change the filter, and put the new oil in. The kerosene will clean any carbon deposits (and unburnt fuel if you use regular) that may have built up. Its exactly the same as 'engine flush' sold at any auto parts store, but 300% less.

So, do this, then see if its still smoking.

If it still is, then youre going to want to run a compression test. This requires a bit more mechanical abilities, and speicalized tools. You can rent them at autozone, and they come with a book to explain it.

obviously, if you arent caught up on recent maintenance then it could be numerous other problems. But if youve changed the oil on time, replaced the spark plugs/wires in a normal schedule, clean or replaced the air filter on a regular basis, then those more then likely wouldnt be the cause.

and sorry i wrote so much, i have no idea what your current knowledge of autos is.

I am about 95% sure it is the Idle air comtrol valve (IAC) causing this. 2 things to check. 1st check to see if your coolant is full. If it is not full it may cause the variable idle. (rev up to 1600 then back down to 700rpm). If the coolant is not low then you need to replace the idle air control valve. It is located on the backside of the intake manifold. Inbetween the fire wall and the engine. Removal consists of : disconnecting two 3/8 coolant hoses from the bottom side of the valve, and removing two ten mm bolts. Once removed installation is reverse. Be sure to add coolant as it will pour out once the lines are removed from the IAC valve. Also instead of replacing the IAC it may be possible to clean it out with carb spray. Clean out the part that has a mesh screen, not the part that has coolant in it. Those are a couple options. I wish you well and keep on asking.

It's more likely that your integra is burning oil. This is because you push your car too much, to the limit that the car may have gone over board. If you look at the tip of your muffler, swipe one of your finger in it, and there is a DARK black stain, it most like burning oil. You may want to do a maintenaince check.

i blew my head gasket by putting oil in my integra. racing =) is your engine built to race? any mods. did you redline any gears?

your racing with an automatic, how much oil did you put in it? a little above the 2 dot or a lot over the two dots?

if the headgasket is cracked and you havent had it fixed or replaced it could be a lack of compression in the cylinders, that could expalin the lack of performance and acelleration you should have it check out soon

you can alwayz check out team-integra.net very useful site for integra owners=)

You have a bad head gasket and it's leaking water into your engine thus creating white smoke, coming from you muffler.

if you were burning oil the smoke would be black...if it's white, you have a water problem..check the head gasket...

putting in too much oil is actually way more harmful to youre engine than not having enough oil.

i would have to say the head gasket. if you feel capable of fixing this yourself, pick up a repair manual, or just take it to a shop. if you keep driving like this your engine will pretty much be blown.

You gotta problem heads man, probably a burnt up head gasket. (Esspecially at 120mph)
