  1. Thank you so much! I am going to clean the screen out asap. As for the flow control valve.. I think I'm at a loss there because I gave in my old p/s pump for the core charge. =( Am I doomed? I am going to try cleaning the screen this weekend, see if that helps.

  3. Sorry to bring this back from the dead, but since I made this thread a couple of things have happened: The power steering pump which was leaking like hell was replaced with a rebuilt one from autozone. The rebuilt power steering pump was installed and fluid was filled and the system did not leak any fluid BUT the steering was still a little stiff but consistant. I posted on here and someone suggested bleeding the system. So today I went out finally since I had time and I removed the rubber hose from the p/s reservoir to bleed the system. I noticed that the hose was "dry". It didn't look like any p/s fluid leaked out of there at all. I had already took out some fluid with a turkey bayster before removing the hose so I dont know if that had anything to do with it but I did expect that hose to leak a little fluid when removed.. but it didn't. I then cranked the engine a couple of times and after a couple of seconds and some large bursts and pops, old power steering fluid went flying out of the hose. I stopped cranking. I replaced everything and filled it up, turned the car on. The power steering was working pretty well. Then I spun the steering a couple of times to the left and right while parked and "froth" came up, almost like a sherbert light red color. It slowly faded away into little bubbles that dissapeared. However.. I dont know if the bubbles dissapeared and were out of the system or they went INTO the system. Because for some reason.. the fluid in the power steering reservoir was spinning counter clockwise.. (why????). After bleeding the system the steering wheel got extremely really really stiff when the car idles. However.. when I stepped on the gas the steering power returned and I was able to turn the wheel. This happened a couple of times and then became annoying... I dont know what to do. There isn't a leak. The fluid is filled properly. Now a couple of hours later even when I give the car some gas the power steering gets stiff. It is not consistant at all. Sometimes it will be easy to turn, other times it wont. Is my power steering pump that I got from autozone defective? Do I need to clean the screen on the p/s rack? Is the high pressure hose in need of replacement? What in gods name is going on!!!!! ::dies::
  4. The hollow bolt doesn't have to be lined up in any particular way? That's strange, I didn't think that there would be enough clearance for the holes. So I should try bleeding the system and see how that helps? If it doesn't then could there be anything else I need to do? Like clean that screen the other posts talk about? PS - I am using Dexron III ATF. The p/s reservoir cap says use Dexron ATF fluid. The one I am using is fine correct?
  5. Okay, I see which one is the air control valve. I do not think it was leaking but I cleaned it up so it should be okay. I also went and got a rebuilt power steering pump with reservoir for $198 from autozone. I came back and installed it and put everything back exactly the way it was and voila, no more leaks and the steering turns. However.... The steering is still a bit difficult to turn, could this be because of that 17mm bolt that has a hole in it which connects into the high pressure steering hose? Because the hole in the bolt and the hole in the high pressure steering hose have to line up, correct? And maybe they aren't lined up? I drove the car around the neighborhood and the steering is consistant but still a bit hard. Could the above be the problem or is it that cylinder with the screen in it which is on the steering rack??
  6. Thank you for your reply, I will see if I can specify things a bit more: A ) It used to leak substantially more when the car was running and driving. It leaked much less when the car was sitting still parked. B ) I would rule out that the fluid reservoir o-ring is leaking because when I removed it the fluid reservoir was one of the few things that was not soiled with p/s fluid. C ) When I removed the intake plumbing, I noticed a "strange" gooey substance which resembled dark grease or sludge that was slightly coated around the intake piping. Could this be what you were talking about when you said "sucked into the engine and are burned with the normal combustion process?" And which valve would this bee, if you could please circle it in a picture I would apreciate it. D ) I would like to (ideally) repair the power steering with as little fuss and $ as possible. I do not think I have the know-how to rebuild the power steering pump myself. E ) Upon thinking about this matter more I am about 100% sure that the source of the leak can be attributed to the circled area on the power steering pump. (generic picture from ebay, not mine): F ) There is also talk of the "Screen" which is located on the bottom, near the rack and tie rods? Is that necessary to clean or suggested? Should I clean that out as well while I am at it or should I leave it alone? Thanks again for the help for those who are helping, I know this is getting annoying. I see that hundreds of people have these problems, thank you Lexus...
  7. Some guidance would really be apreciated... please help.
  8. Should I just get a new power steering pump from ebay and put it in or attempt to rebuild the old one? I have everything out right now, so I am thinking if I should just order it and put in the new one. Also, how likely is it that the high pressure hose could be the culprit? And how likely is it that I could just get the steering to stop leaking by cleaning the screen thats mentioned in other posts and not changing anything else? Just trying to weigh my options here, cause the car isn't in the best shape, I just want it to run so I can get from a to b again.
  9. Thank you, that helps. I still haven't gotten the pump off because of the 3rd 14mm nut, the one closest to the top of the alternator. The 14mm socket I have is too thick, I am going to look for another socket or use a wrench and a cheater bar and get that off, once its off I will definately be using that article to replace the o-rings, and the other thing that should be removed and checked is the reservoir screen on the bottom? the cylinder type thing that has two wires coming out of it....
  10. Where exactly is the o-ring located on the power steering pump and which bolts do I take off? The 2 14mm bolts on the bracket or the three 14mm bolts on the pump itself? The 3 14mm bolts dont seem like they will come out unless I take the others out first because the bolts are long and you can not pull them out after loosening them. Also, could my problem be also associated with the reservoir screen/lens that is on the bottom of thesteering rack? I hear that if you clean that screen.. that the steering gets better.
  11. I took the intake piping off, maf off, air filter off, loosened the idler pulley and took the belt off the pulleys and now I am struggling with the really horrible placement of the 14mm nuts, any help would be apreciated. i know its annoying to help a lexus noob out but i would really apreciate it, i need the car back on the road soon
  12. I searched and I searched but all I found was people talking about the power steering pump problems and not the actual solution. My 91 ls400 leaks power steering fluid like crazy, 1 bottle every 6 hours I would say. I am pretty handy with repairs as I have a 92 240sx that I have worked on by myself and with friends, everything from lsd to suspension and intake/exhaust to body work. Do I need a new ps pump or can I just fix it? If someone can please link me to the thread that tells you how to actualy take it out, clean it up, etc, that would be great! Yes, I searched, the key word power steering pump comes up with lots of results of people complaining and some mods telling them to search, I went through the first couple of pages to no avail.. plz help TIA
