Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

I havea daewoo nubira and we replaced the valve cover gasket yesterday , did an oik change and now the engine is smoking white smoke. Try to check to hoses, could not see a leak. Where is the cylinder...


Hello and welcome to FixYa!

The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.

Hope this helps and thank you for using FixYa! Have a good one!

2005 3.5l some times smokes oil then stops


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 change oil in my nissan titan v8 and after the engine started smokeing what do we do to stop the smoke.


if the smoke is coming from the engine bay, check for spilt oil or an oil leak, especially on the exhaust. clean/fix this and the smoke should stop.

if it is coming from the exhaust, check you have used the correct grade of oil (too thin oil may bypass oil seals slightly) and you have not overfilled the engine and this can cause internal pressure, causing oil to bypass the seals, or even blow oil seals completely. overfilling will also damage the catalytic converter.

Blowing light smoke and burnning engine oil


Blue smoke is usually oil burnig related. White smoke is due to coolant mixing with the oil. (Head gasket leak) You should have the coolant system pressurized by a garage to see if your system holds pressure. This test will tell a lot. Coolant in the oil is a big problem.

Most likely it is oil smoke, if the smoke is black, and the check engine warning light is on, it could be over fueling for numerous reasons.How many miles on the engine?
