All turbos will need seals. Most of the time, the oil vaporizes in to the intercooler piping, condenses in the intercooler, and makes its way out of the weep hole in the bottom of the intercooler. Eventually, a spot of oil will appear on your driveway on the driver's side.

But, normally, turbos on the 850/70 cars will only leak oil during turbo usage, like getting on the throttle hard. Replacing the seal on the turbo is not an involved process, trucking outfits do it all of the time. Remove turbo, replace seal, reinstall turbo.

Take a look at this thread: http://www.volvoforums.org.uk/showthread.php?t=48611

Have you replaced your PCV system yet? Cleaned out the PTC? If not, get an old latex glove, secure it to the oil filler pipe, and start the engine. If the glove inflates, that could be your real oil usage problem.
