White smoke is burning coolant or water.

White smoke is burning coolant or water.

no water loss at all only oil loss no drips of oil
its burning through the exhaust

white smoke is definitely oil.. Purple/blew smoke is blown turbo and black smoke is something to do with the cat IIRC.

PCV?
Valve cover?
Seals?

no PCV bsh stage 2 can
new head cams valves

can the valve cover couse it to smoke out the exhaust ?

White smoke is burning coolant.
Blue smoke is burning oil.
Black some is running rich, excess fuel.

Source, any Haynes manual ever created.

Haynes manual? Would search what that is but im on my phone in class. Ive been told by mechanics that white smoke = burning oil.. and that blueish purple is blown turbo. What oil are you using bez? Have you been using the same kind for a while?

[Leo14]

I mean you could be right. Isnt it possible for liquids to get into the oil therefore burn oil faster? Anti freeze etc.?

White smoke: 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.

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.

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).


Blue Smoke: Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.

How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Black Smoke: Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.

I hope this helps you determine what could be causing your engine smoke, and the possible reasons behind the smoke. Haynes manuals are probably the most popular DIY for automotive repairs in the world, haynes, bentley, chilton all have this noted in their appendixes along with the spark plug corrosion/ color photo info pages.

TIA UPDATE
leakdown test 95%
no coolant loss
downpipe dry inlet dry IC hoses dry
still the white smoke any ideas

[mr shickadance]

this may be a very very very stupid question but does it only happen when the car is cold and disapears when it warms up?

You've had so many problems with your car it's not even funny. Good luck fixing this one.

Any update? Did you find what was causing your smoke? My car is smoking. Even though I have a B6, I have similar symptoms and conditions. Thought I might learn from your experience.
