WTF?

Well, time for my weekly breakdown. Not sure exactly what happened yet. I was driving back home at night and noticed smoke in the mirror, LOTS of smoke. I wasn't far from the highway exit so I planned to get off there. Before I did, the boost drops to zero. I pull in the gas station and shut it off as I notice the oil pressure is quite low. I'm thinking maybe the turbo shaft broke or something and it's pouring oil into the exhaust. Check the oil, and it doesn't register. I pour in a bunch from a partial 5 qt, and get it a little over full. I start it up and it is blowing loads of smoke, but it's white and doesn't really smell, so it seems like a head gasket. My antifreeze looks normal though, so I don't know where the oil went. Antifreeze is a little low. Oil looks normal, not milky.

from the FAQ:
The second category is white smoke:
White smoke and blue-white smoke share some of the same characteristics. White smoke is fuel not being burned. Extreme white smoke can be caused by the combustion chambers cooling down. One cause of this could be incorrect injection pump timing. Coolant getting into the combustion chamber can cause white smoke also. Possible causes are blown head gaskets, cracked heads cavitation, etc.
heavily retarded or advanced timing can make a lot of blowby, the oil gets pushed out... wait, you have that super duper catch can.. so were did it go? :?

And I pulled the hose off of it and it looked like it hadn't been blowing any oil.

that leaves the timing or a sticky injector, in my shallow experience, the IP doesn't have enough travel to start making white smoke, but might be different on a DI.
a blown HG allowing the compression to escape to the next cylinder would make white smoke as well.
but those are just ideas, please let us know what caused those weird symptoms

It's got to be coolant as it doesn't smell and seems very moist. I better get the garage cleaned so I can actually start to work on the thing. :evil:

Hmmm, I think I found where my oil is going.....
I started it and pulled it into the garage, then revved it a bit to see what the smoke would do and to see if the turbo was pushing any air with the hose disconnected.
I guess the highway must have been well oiled behind me. It's just weird the exhaust didn't smell like oil at all.

The exhaust didn't smell or look like oil burning because there wasn't likely any oil being burned. The oil coming from the compressor side of the turbo collected in your aftercooler (make sure you remove it and wash it out, as well as all the air piping before you put the vehicle back in service). The oil from the turbine side of the turbo was sent out the exhaust pipe and was vapourizing but not igniting (not enough heat), hence the white, low odour smoke.

Before despair strikes, is the turbo oil drain unobstructed?
Book the Landy for an exorcism next?

Yes, but the drain had nothing go do with it. The turbine both got pushed out as far as it could go and also somehow lost it's seal, so there was plenty of room for oil to come out into the exhaust. This is why I was able to drain 1/2 quart out of the exhaust. Compressor side was still in place, so it didn't get filled with oil.
I'll also mention that a 1.9 NA TDI is VERY SLOW in a 3600 lb brick. :lol:
