2001 3.0 Diesel white smoke from exhaust video

got to talk to the stealer, and its not the breather that caused the turbo failure, they are sure that its the return oil tube from the turbo back to the pan that was blocked and caused back flow that lead to the turbo leaking oil.

Never heard of that getting blocked!Its usually the oil inlet pipe as I said in my post #21!

The return oil pipe will cause back flow if the oil sump is over-filled!Are you sure your car never run with excessive oil or the dealer didnt over-fill ,at some time!
Hold them responsible!If its either the the inlet or return pipe,then they should have checked these when they have remove and install turbo!

yup, i clarified with the shop foreman, i asked if it was the inlet or the outlet and they said its the outlet. no excessive oils as i check periodically the oil level.

i did held them responsible for the 2nd turbo, unfortunately the very first turbo replaced, it was BMW Phil. who changed it, and they're no longer around.

Hi,
Can you ask them ...why was it blocked and with what?
Its very unusual for the outlet oil pipe to block because its a non-pressurized pipe,unlike the inlet!In my 15 years of dismantling turbos ,never came across a blocked outlet pipe.....dozens of inlet,yes!

they said it was blocked with oil sludge, are they BS-ing me? and they don't know what caused the sludge either

anyway got the vehicle back and been driving it over the weekend.

no loss of power, no white smoke during idle anymore, however there is still that black smoke when you floor it. gassed it on two different stations and no smoke still. gassed it only a little then try to empty the tank before filling up with another station. now its time to check gas consumption as i have filled it up in full. will monitor also coolant and oil levels every two days to see if level gets low

anyway here is a picture of the two old turbos, wondering what caused the bent impeller blades on both. left is the older one, right one is the supposed new turbo that is leaking and was replaced as well.

Turbo #2 LEFT and Turbo #3 RIGHT


Turbo #2 close up

That is some picture of a damaged turbo....

I cant see properly the compressor vanes on the new turbo that was also replaced!But the vanes also look damaged!Is that right?

Anyway,the only way the vanes can get damaged that way is when get a strange object from the pipe that goes to the air-filter!Nothing would go past the air-filter itself,so someone must have left something there ,like a screw !
When they removed the turbo,they must have found bits of the object there,I am sure????
This is the culprit and why you had white smoke..NOT because of a clogged outlet pipe!Because of the "strange object" hitting the vanes it would warp the turbine rod sufficiently to allow oil to be blown to inlet manifold and out of exhaust.
This happened on the first turbo you replaced.you now have to ask yourself who before this,changed your airfilter or did any work around it?
If its the same shop that replaced the turbo,then they screwed up big time ! Use the pictures you taken and hold them responsible!Tell them you will send them to BMW ,if needed.
Good luck.
