I have a T200 machine that took a crap today. Massive black smoke out the exhaust and uncontrollable revs. My son was running it, it went full throttle and would not shut off. it took a minute or two and must have choked itself out due to all the smoke in a confined area. When i got to looking at it, it turns over and seems to have compression with a hand wrench. BUT, the oil on the dipstick was runny and overfull by 3" or so. I always check oil and it has been in the proper spot forever. A buddy looked at it and saw it happening and says the turbo took a crap. However, the tailpipe had black soot but not oily residue. Smoke was deep black when it was running. I have read some threads of possible fuel lift pump as the cause. I can understand the over full oil, but not the run wild condition. Its a deutz engine. I am looking for ideas. Thanks in advance. heres a picture off the security camera of the smoke. Its in the upper left of the video . http://www.youtube.com/watch?v=YipeuzUIRFc

Wow, scary. I have seen some diesels run away due to oil being sucked into the intake via the crank vent when the crank case is over filled. Older VW diesels were notorious for this.
Your friend may have a point with the turbo. You need to check the compressor side of the turbo for oil. It sounds like you have only checked the exhaust (turbine) side thus far.
If everything checks out with the engine, I would likely still change the timing belt as a precaution. It may have skipped a tooth in the process, and the timing should be checked as part of your investigation.
Fingers crossed and wishing you luck.

That was some heavy smoke. It makes sense that the pump leaked fuel into the oil pan and then the pcv system fed it to the engine. These things should come with a emergency damper so you could cut off the air supply, otherwise all you can do is try to kill the engine by running into somthing solid. I suppose if you could get the air filter out and block the intake with a shirt or something but by that time it would be all over with.

I was taught that if this should occur, pull of the air cleaner stack, if equipped, take off your shoe and hold the sole over the pipe. Do not ever use your hand!! Some older Detroit Diesels were equipped with a flap that could be slammed shut over the supercharger in case of a run away.
I pulled off the transfer pump and pumped it against the block, it started leaking fuel out a small hole that must be a vent of somekind. That for sure is the source of the fuel in the oil. http://i1035.photobucket.com/albums/a434/cwatters999/photo-96.jpg

That would do it. Kind of scary actually. There was a guy with an 863 that did the same thing a couple of months ago. If I had a similar machine, I think I would be proactively changing the pump - NOW!! I would still check out the turbo, just in case the thinned out oil has compromised the seals. Better safe than sorry.
The transfer pump leaking is common. They can leak both ways either dump fuel in or suck oil out.
