my car exhaust blue smoke at the time of starting but smoke disappear after few minutes? what i have 2 do?

Question

Car model - Accent GLS, Auto transmission ,manufacturing date 2000

Answer 1

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.

Answer 5

you are burning oil. now the question is how is the oil getting into the combustion chamber? there are two possibilities. one, the pcv valve is no longer able to completely close off the air flow and now allows a little oil to pass into the intake manifold. if this is the case, replace the little buger. two, you have a higher mileage vehicle, and now you are getting oil past the compression rings or the valve stem seals , you have two different options in this situation, short term fix, try a little heavier oil or a bottle of "NO SMOKE" oil additive, long term, either rebuild the engine (or find some one to do it), or replace the engine (or find some one who can for you.) ideally you should go to a shop and let some one run a few tests for you

Answer 6

Blue smoke is the product of oil burning. Oil burning is the cause of worn rings on the pistons or worn valves. You can try going to a thicker or heavier weight oil, or one of those oil additives that will basically have the same effect. But the point remains that your engine is getting a little tired. *Note: your warm up time in the winter will be effected.

Answer 7

You need a valve job, oil leaks past the valve stem seals while it is parked and collects in the cylinder, it burns off quickly right after you start the engine, hence the smoke...

Answer 8

Blue indicates oil, white is water, and black is fuel. Many possibilities for the location of the leak(s) in your engine. The best solution is to take it to a trusted mechanic to see if he can find the source for you.

Answer 9

This means that your valve seals are leaking. To replace them you would have to get the heads pulled. Chances are im guessing you probably got 100k miles or more on it so it may be more cost effective in the long run to just replace the engine.

Answer 10

blue is a sign of the oil i think.....you better get it to a shop and have it checked out before it gets worse! Good Luck
