Hello i have Nissan Altima 2002 2.5 and sometimes blue smoke comes out and sometimes its fine and the engine does not have any noise and i would like to know if this can be a simple fixing or a big problem a guy told me that probably the oxygen sensor needed to be changed but i don't know if that's true Thank You very much and i hope to hear soon from you

Really don't think an o2 sensor will solve your smoke problem. Blue smoke usually indicates that the engine is burning oil. This could be from piston rings, valve guide seals, or PCV system issues.

Check your spark plugs and see if you can tell which cylinder(s) is burning oil.

OK i'm going to check the spark plugs again the last time i checked them they were fine they were clean and i don't see anything wrong with the spark plugs but i'm going to check or do you think i would have to use any additive

Just a heads up:

They thought is would be good to have the catalyst attached to the exhaust manifold up close to the engine because it would heat up the catalyst quicker. The downside of that design is if the catalyst started coming apart, the exhaust pulsation during valve overlap would suck the crap,which acts like sandpaper, right up into the cylinders. The engine would eventually burn excessive oil and even have low compression in some cases. I've seen it happen on a 3.5L Pathfinder. Avoid the exhaust manifold baby cats in my opinion if your looking for a car. If this is the case with your vehicle, it needs an engine and cat.
