my honda smokes blue out of the tail pipe whats wrong with it?

It is burning oil.

sounds like it's burning oil. Check your dip stick often.

The rings or valve guide seals are going.

Have it serviced like right now!

Blue smoke is bad. Get it checked out asap before your engine blows.

Blue Smoke: 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. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles. How did the engine oil get inside the cylinder in the first place? 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.

Oil consumption caused by worn rings, or valve guides

Most likely, you are burning oil. This can be caused from over filling your crankcase, a bad piston ring, bad or blown gasket, etc, etc. While not a major problem immediately, if left unrepaired, you will be faced with a larger repair bill later. Sometimes its a really easy and quick fix, I would find a reputable mechanic who specializes in Honda repair to check this out for you. If your car has white smoke, you are burning coolant, also a very bad condition for you vehicle as now you are losing cooling fluid which may cause the engine to overheat.

Blue smoke is from oil entering the combustion chamber or the system is running too lean. This is generally caused by leaky valve stems, incorrectly adjusted valves, worn piston rings and/or scored piston walls. Try using some Engine Restore oil additive for a couple of oil changes and if that doesn't fix it then have a mechanic check for worn piston rings or piston walls. They shouldn't charge you too much because they have tools that they can insert into each spark plug hole and test for compression and visually see the walls without taking apart the engine. If you ever see white smoke then that's water getting into the chamber and could be a head gasket going out. Black smoke is when your car is burning oil or running too rich.
