I want to thank you guys for this thread. I own a 1993 LS 400, and have been having the same issue with white smoke with loss of power steering fluid. I have had a full tune-up, timing belt, water pump, power steering pump plus reservoir, pressure hose return hose and over the last 3 months $250 worth power steering stop leak fluid into this beautiful car and still white smoke. Thank you, thank you, thank you again for this post. Can I just ask for the correct name and location pic? If you have any diagrams that would be awesome as well!!! Again thank you!!!
