steering/smoke problem

I have a problem. My car smokes, and it smokes a lot. Well mostly when I accelerate hard on the freeway. I believe that the smoke is coming from the steering rack and dripping fluid onto the exhaust. I replaced the two rubber o-rings on the return hoses myself and hoped that would solve the problem. It didn't. In fact I think it may smoke more now than it did before. And now I'm starting a job on tuesday and need a way to get around LA. Is it likely that the entire rack is bad or could it just be a bad seal? Is there a common problem other than the o-rings that may be causing the leak? If I had a rack and the time to switch it out I would but that is no longer an option. Does anyone have any advice to give or reccomendations of what to do next? Thanks for any help you can offer.
Regards,
Scott
