Smoke could be:
1-Transmission overfilled draining through the vent on the exhaust ..check the level.
2-Valve cover towards the rear of the engine leaking oil down on the exhaust
3-Head-gasket as they do leak in that corner, also down towards the exhaust....
Degrease the engine big time...and drive it for a while......you would be able to see the location of the leak....in reference to your other question, the heads don't usually crack, and seals don't usually wear on the m104, unless horribly abused.....
good luck

It sounds like from what you describe, the smoke would be from near the engine or mid exhaust. This cloud of white smoke is coming from the tailpipe. I'm sure hoping that it's not a head gasket.

I say get it running right and drive it for a while, monitoring the coolant level. White smoke could be a chilly night and/or a crudded up motor from the misfire.

All I know is the exhaust REALLY stinks. It doesn't have the typical rotten egg smell of unburnt fuel anymore. It has a strange smell that I haven't smelled before. I wouldn't say a sweet smell. Hard to describe the smell pretty hard to handle though.
I was getting a code 13 (running at lean or rich limit on Lambda IIRC) but would a misfire cause this?
