White Smoke from yaris D-4D - Page 2 - Toyota Yaris Forums

Oil would be bluish,unburned fuel would be black,water would be white,i cant think of anything else that would burn white unless you are referring to copious clouds of strange smelling smoke coming out of the cabin

Oil smoke is bluish white, and people like you and me who are familiar with it would notice that. Not everyone would, and some would just call it "white." You'll note that I referred to the bluish white oil smoke in my first post. But as I also posted, unburned Diesel fuel comes out just plain white. Hang around a trucking company or truck stop a while and you'll see white smoke from the stacks of trucks with intact head gaskets.

ok, here's the list....of smokes and color for everyone to know and read and deal with

black: fuel, either unburnt or half burnt. or rich from bad cat during accel.

blue or blue tinted: oil, either in the combustion chamber or leaking onto headers/catalytic converter

white: water. coolant will have a tinge of smell to it. if you wipe the tailpipe and smell it it will smell sweet and will still smell like clean coolant.

now, there is a possibility of white and blue together to make white....and you wont be able to tell if it's blue or not. so...that's usually a busted head or head gasket tho.

another thing that noone's thinking about is coolant in the turbo. newer diesels have it so u may too...check it.

I work on diesels in truck and I am not sure about the D4D Yaris but it could be a semi clogged injector. Previous fuel left in the cylinder bore could cause it. Run some diesel injector cleaner through it. A piston ring I would say would leave a black cloud due to oil seeping into the bore.

Thanks
I filled the level of the engine oil. I checked it after driving for about 20 mins it was back low again. The engine oil is basicall leaking through into the exhaust system and burning causing white smoke. Could be the turbocharger itself but there is no power loss at all.
thanks

Turbocharger oil seal seems a likely culprit. It's a job for a professional now.
