Noticed my 96 LS with 180k is leaving a spot on the garage floor each night. I havn't had time to do a thorough investigation, but the oil seems to be dripping somewhere from the front passenger side of the engine. I'm hoping it's a valve cover gasket and not a cam seal as the timing belt isn't due for another 50k miles. Oh, almost forgot, it's definitely motor oil and not PS fluid.

That's the one. I don't remember the part # I asked for but I got it from searching online. Whichever one it was it was wrong. Toyota said it was a Lexus # and Lexus thought it was a Toyota number. When I explained to the parts guy where it was he found it quickly. I'd have to check the bag to see what the part number was. The O-ring was $7 before I sufficiently shamed the parts guy to the point he sold it to me for $5! They probably paid 10c for it.
Installation was straight forward. As people have reported, there is one bolt that is a pain to get to. I had to have my wife use her smaller hands to get it back in position. I also replaced the 6" low pressure hose and clamps. Since I didn't mess with the high pressure side mine seemed to have zero air in it when I performed the bleed procedure..

That's the correct part number, I fished the bag out of the trash and checked it. You can remove just the reservoir and that's what I did. It's still a PITA to get on and off. If anyone has an older LS and is doing the TB and water pump, that would be a great time to swap the O-ring out. It's the lower plastic cover under the distributer and rotor that causes the problem.
