Question about 2002 Nissan Altima

2002 nissan altima + black smoke coming out of tailpipe.

I have a 2002 nissan altima (2.5) and when it is running there is black smoke coming out of the exhaust tailpipe. Also I have noticed that there is a loss of oil level. No oil drops visible, no oil leaks visible.

Smoke is black, not blue or white.

Can you help guide me in the right direction for correcting issue???

I appreciate any assistance that you may be able to give me.

Thank you,

To begin with, check for fuel in engine oil and do a compression test. If fuel system is not functioning properly (running rich) that will point you in one direction (temp sender, pressure regulator , map or airflow sensor etc) If compression is low, you may have internal engine problem (burned piston, broken ring, or combination of fuel problem causing gas washed cylinders)

I've had the same problem, have been adding AT least a quart of oil a week, apparently there are tons of sites with same info and everything I've done to date has not resolved the problem-- new cat, new spark plugs, new coils, new O2 sensors...

WHY Nizzan 07 Black smoke coming out tailpipe and consumption of oil


There are several things that can cause black smoke. Leaking fuel injectors, stuck valves and so on. Oil consumption can be from a leak, bad seals and a dozen other things. Your best bet at this point would be to take it to a mechanic before you do some catastrophic damage to your engine.

2002 nissan altima that starts but has low idea and when i hit the gas there is black smoke.


well black smoke means you are burning up engine oil. low idle means you have less compression. you might want to check your gaskets! does th engine oil level go down after a drive?

Black smoke coming from exhaust pipe


black smoke is coming from exhaust possible causes--- excess fuel enters cylinders and does not burn completely. poor fuel milage is also a common complaint, when black smoke comes out tailpipe its running to rich!! This can be caused by anything from a computer malfunction to a leaking fuel injector. A possible fix would possibly be a tune up or carburetor/fuel injection work. run some good injector cleaner in it, it may fix the problem. but if not check it out further. good-day !!

2007 Nissan Altima - smoke from tailpipe


It sounds normal white smoke comes from moisture in the air as it's burned and the air temprature is different. it creates steam they gray smoke is a little harder to decide what it is, normally gray smoke is related to oil burning and black is over fuel, depending on how many miles it has on it it could have bad valve guide seals but would not worry about it.

Nizzan 02 Black smoke coming out tailpipe and consumption of oil


Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. 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 fuel odor. Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer 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.
