I had a small leak. On a hot day in houston it turned into a very severe oil lossage, while going down the freeway. When I got off and came to an idle the indiacator to display "No Oil When Safe Presure Stop Engine" which saved the engine. So now I'm looking into the repair.
oil leak was small and now it really bad
turbo oil drain line.
Had the same problem at about the same mileage on my '95 850. Cheap repair.
The problem started as a small drip and pooled above oil drain plug. The couch washer was replaced and oil pan re-installed. The problem still exists.
May be turbo that went out. Smoke comes out of the muffler,was thick white smoke when driving the vehicle an now after I left it a few days turned it on an now black smoke!....y??
Basically getting all the same symptoms.
