What's your oil consumption like? Should be no more than 1 litre/1600km. Did the repairer put the right grade in - if it's too thin you may get an issue perhaps?

I know you said you replaced the turbo, but was it with a new one? It's possible the centre bearing has a problem and is leaking oil into the exhaust stream. This is potentially more serious if you get oil into the inlet stream as the engine can run on oil and will rev until it destroys itself. A very rare event but it can happen - especially given oil is just a thicker diesel!!

Everything you describe sounds like oil burning, but I have seen coolant failures laying down a cloud of short lives steam (though not for very long as the engine tends to overheat very quickly). I also would not expect steam to linger long in your climate either. One of either your coolant or oil levels will show which system is the likely culprit.

I suppose it's just possible you may have bad fuel on board - have you used different fuels to eliminate that remote possibility (has someone refuelled your vehicle and put a small amount of petrol in it by accident and kept quiet?). How is your fuel consumption under normal driving?

no figures on the oil consumption since the car has been with the stealership for 8 months. oil they put it with the new turbo is of 0w30

yes, turbo is new, cost me over $2000 for it. new turbo was leaking oil to both inlet and outlet (intake and exhaust), intake manifold and exhaust full of oil and had to be re cleaned. my update is on the latest turbo that was installed since the 2nd brand new one was shot as well.

i'm thinking its between the coolant or oil as well, as they are the ones circulating inside the engine, however i still don't have much time with the car to test it further. once i get it back will carefully monitor the level.

as for fuel and its consumption, the same thing, i could not test different fuels and its consumption as vehicle is back at the stealership for addition problems they made with the car (they broke my PDC, door actuator, did not attach suspension, under chassis cover properly)

once all the small things are sorted, that's when i can monitor the gas, oil and coolant

thanks for sharing you input

You really need to determine whether its coolant or oil.!As you know ,its easy to differentiate !

You say the exhaust was cleaned!If oil went into the exhaust when turbo broke,then unless they put a new exhaust in ,you will always have oil residues in the exhaust for a while until it all blown out,no matter how they claimed to have cleaned it!

The other issue is finding out why they think the turbo broke?Dealers make a common mistake in replacing the turbo without analysing why!A reason for turbo breaking is poor lubrication and this usually means thats the oil inlet pipe to the turbo has a blockage!Seen it loads of times!
Good luck

the stealership concluded its oil for sure since the brand new blown turbo is leaking oil to the intake and exhaust.

you are correct with the stealers not analyzing what caused the two blown turbos. never gave me a concrete reason why the first turbo blew, but when the brand new turbo also blew, then they started to check what really caused this and said its blockage in the intubing that lead to increase in oil pressure to the turbo. similar part to yours, but sounds opposite of what you suggested. at any case logically, either too few or too many oil in any particular moving part can lead to premature wear, that is for sure.

anyway my update is after they have deblocked the intubing and installed another brand new turbo, that it still smokes.

brought the vehicle back to the stealers so momentarily could not do further testing.

thanks for the new angle on why the turbo blew, it seems likely that could be the cause.

in general however, it could even be both coolant and oil that is leaking.

lets see in the days to come.

thanks

This is actually weird because I have never seen very white oil smoke? It always has a blue tint to it.. however speciel oil like tranny oil etc. maybe more white-ish, I am not sure. . (not that im saying its gearoil in you case.) But what kind of oil is the turbos runing on ? Engine oil ? seperate speciel oil ?

turbo runs the same oil as the engine oil.

Hmmm ok, that just makes it even more strange! (white color)
