After I drive my '86 930 for about an hour or so I smell this awfully strong sulfur(rotten eggs) odor. There are no leaks evident on the garage floor, and no smoke. It is hardly noticeable from outside the car, only inside. It does not smell like oil, and oil consumption is normal. I searched around and discovered that a phosphorous/sulfur compound is added to gear oil to combat breakdown. I bought the car 2 months ago, and this has been going on about 3 weks. It shifts ok(except the typical 1st-2nd quirks of the 915 tranny). The car has 27,000 miles and I have no idea if the gear oil was ever changed. Could this be a sign of gear oil burning? Time to change it and try swepco 201? I know it's important to recognize all the different smells a car can make, but this one I'm not sure of. Any ideas?
