Oil is getting into the cooling system through the oil cooler. the oil cooler is located under the intake manifold. After replacing oil cooler you need to flush the cooling system several times to remove all of the oil sludge

Blue smoke after being driven for awhile


if you can then smell the smoke. if it smells of petrol you will need a tune on your car ( getting too much petrol ). if it has no smell or very faint then it could be your head gasket. (water getting to the head causing steam ) worst case would be piston rings expanding through heat and letting oil through ( smell of oil burning ) check oil filler cap and dip stick for white gunk/check exhaust for water dripping out. these are head gasket signs

White smoke petrol 1.4 renault clio.not stem


White smoke: White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.



It is also possible to be a engine problem you should immediate visit a car service.

My toyota after along drive white smoke comes out off the silencer could it be the turbo because the turbo shaft play.


White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area.

Oil is dripping and touchin the exhaust pipe under the car making smoke could I drve my car until I get it fixed?


Whenever oil is getting on the exhaust the possibility of a fire can be fairly high, the amount of oil is key, if you just get a little puff of smoke now and then while driving you should be ok until you can find time or money to get it fixed, if it is really smoking allot then you shouldn't drive it.

Hi I have a Golf MK4 1.6 16v S and have noticed smoke coming out of the exhaust on a cold start. The smoke only lasts for about 30 secs and then the car is fine - it drives fine also. I have done some...


"smoke"?? you sure it's smoke & not water vapour/condensation?
the gunk in the oil cap tells you nothing really, you can check the coolant reservoir for contamination.
so, to sum up, i don't think you have a problem.

Water is going somewhere on a 99 gr prix 3.1 no leaks but white gunk under oil cap. No smoke or oil in water. but i think their is water in oil. is that a head gasket problem?


If there is water in the oil, yes it most likely a head gasket/cracked head/block problem. Check the oil level on the dipstick. Is the oil level indicated too high? Drain the oil completely into a clear container and let it set overnight and see if water separates out from the oil. The white gunk is a sign of moisture in the crankcase. Short driving trips may cause this also as the motor doesn't get warm enough to evaporate the normal moisture out of the oil.

Why do I have white smoke coming out the back of the engine by the heater hoses and out my exsaust pipes? Also my car is idleing rough and there is no dexcool in my oil....thanks for your time. Your web...


White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.

Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.

How did antifreeze get in the oil or cylinder in the first place? The engine probably overheated and a head gasket failed due to excessive heat, thus allowing antifreeze to enter the cylinder (Where it is not meant to be).
