I have a 2001 Kia Sephia, it blows a lot of white smoke right a way. I start it right up, it runs real good, I checked the oil for water and there is none. What could it be, Please help.... Thanks Dave

There are three common reasons for oil on the plugs. A blown head gasket, worn valve stem oil seals and worn piston rings. The most likely reason will probably be the head gasket.
Check the coolant overflow tank for oil floating on top of the coolant. This is a sign of a blown head gasket.
For Valve stem oil seals check the following... On a Cold start you get a large thick cloud of blue coloured exhaust smoke. You also get the same smoke when going from idle to higher engine revs. Such as pulling away from a red traffic light after sitting waiting for traffic.
Does the vehicle use a lot of oil? Does it have excessively smoky exhaust gas, usually more of a grey/white colour, when driving? Has it lost power? Look in the engine air filter box. Is there oil? Worn piston rings sometimes cause 'blow back' where an oil/air vapour is forced back through the air intake into the air filter box.

Destroy your radiator, drain all the oil, and redline this piece of junk

blowing white smoke possibly means steam from water, you may have an internally blown head gasket.

Ah oh..white smoke is water in the cylinder and cap blowing off is compressed air in the crank case..sounds like you have a blown head gasket or intake or both...have your radiator and block pressure tested..if gasket is leaking it will fail to hold pressure.. Check your oil for water sometimes a bad intake gasket will let water in the oil.good luck..

Sounds like a bad coil pack 1 and 3,if you change it and it's no help,see if you can find the vacuum hose that goes to the fuel pressure regulator, ,if there if fuel in the hose ,it's bad

Did you change the oil and oil filter.The oil might not be circulating well in the engine if water got into the oil after the head gasket failed.You might have to remove the botton engine oil pan and check the oil pump as it might be covered with white emulsified oil.If the oil does not circulate it can cause the engine to heat up.Did you remove any trapped air in the water?There should be a bleed valve.Make sure you turn the cab heater to the hot when removing any air fro the cooling system.Check for airlock.

sounds like intake gasket blowed or head gasket is water in oil or oil in the water if so there is the prob

Black smoke is fuel.
Blue is oil.
White is coolant / water.

Fuel is caused by timing and cold start system and requires some discussion to clarify.

Oil burning only on start is caused by failing rings on your cylinders. Oil then enters the combustion chambers and burns when you start the engine. If it continues to burn when running in particular when you accelerate it will also indicate ring/cylinder failure. It can also be from a failing head gasket where oil travels from the lubrication system into the combustion chamber. Some of the anti smoke additives available at the auto supply store do help.

I doubt you are seeing white as you say is smells like exhaust. White is coolant in the combustion chamber or exhaust system.


Hope this helps you.

the head gaskets are blown you can believe that anytime on any engine gas or deisel that you get oil in the radiator and there water/ antifreeze in the oil pan the gaskets and or cylinder heads are bad

change the starter motor.
