    Default Civic 99 PS Noise

    Salam all PWs

    My civic started making GHOOOON GHoooon noise with acceleration a few days back. I went to my mech, he diagnosed it to b the timing belt tensioner bearing. i was not convinced, so i told him to remove the power steering pump belt & drove the car for a day & there was no noise.
    Later it was diagnosed as the bad power steering pump pulley bearing. the bearing was changes & for that whole the PS pump needs to b disassembled. after the bearing change the noise vanished. i drove the car to my home & parked it 4 the night. next morning i started the car & the PS pump started giving a loud grinding/ zooon zooon noise as it was low on oil. i checked the oil level it was ok & there was no leakage. But the strange thing is that there r numerous small bubbles in the PS oil in the bottle.
    I researched the internet & found out that PS pump is sucking air from somewhere so air is causing the bubbling & the noise.
    I changed all the rubber o-rings but nothing helps. The oil is clear & no sludge is there.
    I m using Zic oil for PS & never had a problem before with it. My mech told me to put in a small amount of engine oil in PS fluid as it is too thin but i m not convinced with his logic.
    The pump's inner parts were put back very carefully as per the Service Manual & there was no visible damage or scratches on any inner part. all new & shiny. The PS system was also flushed b4 putting in new oil so there is no blockage as well.

    plz giv ur suggestions. To me the problem is of air getting into the system but from where?

    i was searching for the images for the ps pump, is it the bearing that is exposed once the pully is removed or housing needed to be opened?

    The pump has hand selected parts that need to aligned back in the exact same way they came out, new bolts need to be torqued very evenly with a small torque ratchet (the force required is about 10 lb/ft. And the centre O ring along with the rotor seals need to be changed with brand new OE parts whenever disturbed and drowned in PSF when assembling.What fluid did you use? Honda PS systems do not like ATF in them.

    herez why i asked, if the bearing was changed by only the removal of pully, then only seal that pump can suck air is the pully shaft seal under the bearing, and if housing is opened for any high pressure device such as car ac compressor or ps pump only torque wrench tightened bolts will ensure even seating of housing together or else it will make problem only on high temperature, perhaps thats why they always say to change the whole ps pump no matter what happen to that jack thing. anyways will be following thread and waiting for updates as i also need to have work done on my city 2k ps pump

    Edit: xulfiqar commented above one as i was typing mine reply

    I did align everything back in the exact same manner as described in Honda service manual. Every alignment mark mentioned in the manual was aligned perfectly while assembling it back. Used PSF also when putting the parts together.
    The centre seal u mentioned is the same which is on bearing side?
    No I didn't replace that. I replaced o-rings of both inlet & outlet pipes.
    The pump worked quietly till I got home. But started misbehaving in the morning.
    Wat abt the bubbles, it's like surf JHAAAG. Which disappear after u turn off the car & oil becomes clear again.

    I think it's the bolts on the housing which r not evenly torqued. Believe me I Hav never seen a torque wrench with any mech
    if problem persist then I will use Honda PSF.
    Will update u soon after re torquing the bolts by ANDAAAZA

    The centre seal is between the pump halves - and the foam you see is the oil being beaten up with air by the pump, You need to bleed it out (move steering lock to lock 4 or 5 times)If that does not help then the pump is taking in air, specially if you can also see loss of fluid.

    I did the bleeding process numerous times. The bubbles r continuously there. The steering feels quiter on the extremes but the oil boils out on turning to extreme

    Btw I just retourqed the bolts equally by just hand tightening them then gav a 1/4 turn with wrench in cross fashion. The grinding is reduced by 25%

    the little vanes are chamfered on one edge - and ideally should never be taken out of the rotor or their housing, If they are installed wrong your pump will eat itself to death very very shortly.you saying that your torquing quitened the pump is proof that either the seals are leaking or the casings have warped or both. There is no way you can mimic equal torque unless you use special tools, andaaza does not work in every case.

    U r right abt the torque procedure. But it just reduced the noise.
    Abt the vanes. They r rounded on 1 side & that rounded side is to b kept on outer side. I did exactly the same.

    its a basic vane type hydraulic pump - nothing special, but the part - that says to replace all rubber parts was overlooked by you along with the part that said to torque the bolts to correct level and when you replaced the bearing is the front seal riding on the same part of the shaft or is the bearing not housed correctly.dont torque the bolts more than required or you might upset the rotor housing which can then be scratched to hell in seconds.

    The seal behind the bearing fits separately in the housing b4 fitting the rotor shaft. The pulley when fitted 1st had a slight limp but was immediately taken apart & bearing reseated. They pulley now moves without any wobbling. After all that the pump worked noiselessly as I said earlier & their were no bubbles. The grinding started alongwith the bubbles.
    Should I apply liquid gasket on inlet/outlet pipes b4 fitting them?
    It already had traces of liquid gasket on both pipe joints when I dismantled it. I think the previous owner had done it.
    The pump produced same grinding noise abt 3 months back so I flushed the system & filled new oil. Then it became silent. Now again the noise os same
