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 have a 1992 dodge ram van 250 and its smoking really bad,


Black smoke is too much fuel, a rich mixture.
Blue smoke is oil burning, rings worn or valve seals.
White smoke is water, a leaking head gasket.

Black smoke indicates no air, check your air filter, if you have done that and it is ok, check the PCV valve. Thats about all that I can suggest. Hope that helps.

2003 chevy impala makes clicking noise/smoking thru exhaust


the clicking noise could be eiter a valve or piston. the smoke out of the exhaust means different things depending on the color and how much smoke. Check your air filter and make sure oil is not backing up into it. Also, it may be a good ideal to go ahead and change the oil even though you arent at 3000 miles, unless you just changed it. Change the PCV valve also, if itis clogged it will give you problems. Has the check engine light come on?

I just bought a 96 dodge caravan 2 days ago ive drove 150 miles today and when i went to shut it off it had smoke i raised the hood its coming almost directly from the front of the van i went to leave...


How low was the oil? It could be something as simple as some oil is leaking out of the valve covers and once it hits the exhaust manifold then it starts smoking. Usually smoke coming from the engine compartment is a result of that. Look and see if it leaks any oil while you have it parked in pavement for a while in case it has something to do with the oil change.

Good Luck

The plenum problem should not affect compression tests. It allows oil to get sucked into the intake and will cause carbon buildup, plug fouling, and pinging. If you have zero compression on a cylinder, it is usually a valve problem. Even a burned piston will make some compression, unless it has a big hole in the middle.
Sorry, but if your compression results are to be trusted (and it seems they are), then you have to tear a head off to find the problem, or at least get a borescope in it.

Losing oil into the air filter.


If you have a pcv valve check it (shake and it should rattle) Make sure that vacuum line to it is clear and has vacuum. If you have lots of smoke coming out of the oil fill with cap off, likely you have worn rings or a broken ring. If so the pcv cannot handle that kind of crank pressure, engine needs rebuild.

Heavy Smoke


Yeah,,your engine is showing signs of wear, if it blows a lot of oil out the back end after sitting at a light or stop sign,,then that is a sure indicator of Valve seals needing replacement,,,but it also sounds like your engine is worn out Piston Rings and all.
You could try a product which is used on just about every drag racing strip,,it's called Lucas Oil treatment,,,i don't promise that it will solve all your problems,,,but if it don't help,,it sure wont hurt.

Best of luck to ya.
