Sounds like it is the valve seats. However normally it will stop smoking after is runs for a while if that is the problem. Does it run good? Because if it isn't the valve seats then it is the rings. Or a big scratch in the cylinder wall. Then most of the time it will loose compression. If it isn't smoking real bad then you can get an additive to put with your oil that will make it stop, maybe? It is about ten dollars and you can get is at most autoparts stores. It will just take a couple ounces of it. Follow the directions for how many qts of oil you have. After you change the oil in the motor take a magnet and run it through the oil and see if there is pieces of the rings in it.

Hallo,Why does my BMW produce a cloud of smoke when i ignite.what could be the problem?


What color smoke? White, blue? Blue smoke can generally be pinpointed to bad rings as fuel is get past the piston in the combustion chamber. White smoke could be a myriad of things but usually means there's un burnt fuel in the combustion chamber.

When making a turn car saputters and blows a cloud of white smoke


Sorry to tell you this is most like a head gasket leak, or a crack in engine cylinder head. The white smoke is usually anti-freeze burning. When the motor heats up the metal expands and can plug the leak. Do a search on you tube for Scotty Kilmer He has some good videos and information on head gasket leaks. It's usually very expensive to repair mechanically, but he suggests some sealants. If the leak is not too bad the sealant may work. Some cars are notorious for bad head gaskets.

The other thing it may be is oil burning if it's more of a blue gray smoke. When the car sits overnight, on older cars if the valve seals leak, some oil can may accumulate down into the engine cylinder. When the car starts this burns off. If a piston in the motor has a broken ring it can continue to smoke.

The best way to determine your problem is to check the levels of antifreeze and motor oil when the car is cold. Do NOT try to check the antifreeze when the car is hot, or you can get sprayed with hot antifreeze. Good luck.

Engines idle goes up and down after warming up and blows blue smoke


If the engine idles for a while then blows blue smoke this is an indication of oil passing the valve stem seals and being burnt in the combustion process. ( When you are at lights and they change and you accelerate away leacing a cloud of blue smoke this is worn valve guides and failed valve stem seals) As for the idle it could be the oxygen sensor is coated with oil and soot and is malfunctioning henace the cpu cannot regulate the fuel setting correctly. Have the valve seals replaced and clean the Oxygen sensor and check for other fault codes

My 2007 Sorento is a 2.5 diesel and has all scheduled service by the Kia dealer. Its done 25,000km goes well in all respects but after being parked for 8 hours it blows a huge cloud of blue smoke on start...


blue smoke would show a lean condition. most likely a fuel line leak between pump and tank not a pressure leak.or a check valve is allowing fuel to run back to the tank
