I've seen worse volume of white smoke when head gasket leaking...could be ...look for oil in antifreeze and antifreeze in oil.
some additives will seal off that leak. sometimes retorqueing the heads will stop the leak. I once put ground pepper in antifreeze and stopped a head gasket leak that was leaking outside the motor. it degrades after a year tho. try that silver flake radiator fix a little at a time so as not to plug the radiator or heater core, thats a risky fix.
try pulling the spark plugs one by one and look for a wet plug .might
indicate a leak into that piston.

Head gasket yes, bc antifreeze is entering throught the oil ports or down throught the rings, if the water get to the oil it will wipe your bearing out

SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

SOURCE: white smoke or steam coming out of exhaust pipe,

Its funny that everyone has solved the problem without any answers to critical questions. In this case, everyone is right and everyone is wrong. ONLY careful testing and observation will determine if there is an actual problem. I do not solve problems just to be first. Even in a hands-on situation I refuse to jump to conclusions before testing, otherwise you run the risk of at best, "chasing your tail" or at worst, tearing into a perfectly good engine to prove nothing!!!
Happy New Year!!!!

SOURCE: 1998 leganza motor smokes when it warms up

If the smoke is white, or steam it is water. you might have cracked the head or warped it. Did you get it looked at before you put the new gasket on? If the smoke is black then it is oil. Do a compression check and see if you don't have a bad cylinder. They should all be about the same give or take 5 lbs.

SOURCE: 1992 Toyota Previa van,Oil dripping onto exhaust manifold, replace head gasket? need a free manual!

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.

White smoke from engine


Coolant leaking on engine and burning

Apr 27, 2015 | Cars & Trucks

2 Answers

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.

Kia Sedona oil light white smoke


Are you sure this is not the low oil pressure warning light, bet that it is. The white smoke may be from a blown head gasket, any shop can tell you just by the smell of the smoke, if it smells "sicky Sweet" then it is coolant being burned in the engine and you have big problems.

How do you know if you have a blown head gasket?

My kia sorento is white smoking and rough idling please help


this is usually the sign of a blown head gasket. you may also want to check your catalytic converter . look for signs of water in your oil by checking your dip stick. if your oil is a brownish color or you see water on the dip stick, your head gasket is blown and the rough idle is being caused by water leaking into the combustion chamber. when engine coolant is burned it gives off white smoke and it gives off a kind of sweet smell from the exhaust. if the exhaust smells more like oil, piston rings may be the cause. a compression test will help get you on the right track.

I have mud like stuff in my radiator


Mud like stuff? You mean oil like stuff? Is it white and greasy looking? This is not good. Check your oil for water, sounds like you have a head gasket going. Look for steam out the exhaust after it warms up. Drip some oil off the dipstick onto the hot exhaust and see if it sizzles, (water) oil will just smoke. Keep an eye on the temp gauge. Don't let it overheat. And shut it down if it does. A radiator shop can tell you if you have lost compression. Hope this helps.

97 kia sephia smokes when first starts, smells like exhaust smoke


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.
