    Default BX madness

    I need help (or therapy). The little red BX has developed a leak at the octopus. Hard to get to (understatement) and obviously difficult to know which pipe it is. The frog engineers (?) blew this one, hydraulic suspension - absolutely brilliant. The mess of return pipes to the reservoir - absolutely dumb.
    Anyhow enough social comment. OK, what next? First are octopi available anywhere, failing that any advice from anyone who has survived the trauma of replacing/improvising this evil ratsnest would be appreciated.
    Beermoney from Simsmetal looks more tempting every passing day.
    Please help or send Prozac.

    New ones are back in stock, search my previous posts for part number. Have this number first before dropping in to a citroen dealer and ordering it. Just on $115.00. Will take about 4 hours to do gently, add 1 hour for doing for the first time. Also bypass home made jobs are possible. The octopus comprises 3 main lines with branches. You can learn to replace just one if your happy saving time, then doing the other two down the road.

    So many choices

    To make the job significantly easier, I totally recommend removing the r/h driveshaft and engine stabiliser mount. It may sound like a pain in the arse removing those bits, but you will definitely appreciate it once you start getting your hands in around the height corrector.

    Also, budget for large quantities of patience.

    Once you successfully replace a BX octopus, make sure your next car is a Xantia VSX that needs its octopus replacing.

    After that you can go directly to Heaven, no further qualifications required.

    You don't, by chance, need to take the engine out for anything else do you?

    Thoroughly worth doing even if only to replace the octopus. Advantage of being able to replace a bunch of other bits if required and give the whole thing a clean. Pics of my octopus effort in another thread.

    I just had the engine out of my valver, inspected the octopus, thought it looked OK and did not replace it.

    3 weeks after the engine was back in my heater tap broke and the octopus started leaking.

    Lesson learnt!

    Had an old octopus sitting around for potential spare sections of hose/reminder of what the devil looks like, and went to show a visitor just how stupid the setup is. Naturally a hose fell off one of the cone shaped collectors with barely a touch despite looking in OK shape.

    I dread the day when the one I've installed in my white BX decides it's time. I really hope it makes it to 10 years or more.

    It should last a fair while. The one in my car looks original, has done 200K and is 24 years old (4 months younger than I). This is it's first leak, which could have been caused by my fettling around with it.
    Hopefully the replacement (oem Citroen) will last a similar amount of time. I just need to make sure it is fitted and run correctly so it is not under any undue stress, which would have been easier months ago with the engine out!

    I don't see the octopus is a design flaw, sure it is a weak link when the car gets to this age, but I just see it as a general service item. Rear arm bearing, clutch, etc take a similar amount of time to remove, repair/replace, and refit.

    Check if the timing belt is due for change and change the water pump whilst you have the driveshaft out and timing belt off.

    Might as well do the hydraulic pump and belt while at it, and repaint the window wiper in satin black they are prone to start rusting. Oh!!! does it ever end

    I have banged on about this so much but always with a warm response...Main octo when it fails will most likely be the main low pressure return lines/chamber..Have a logical look at everything and bypass this part of the octopus straight back to the reservoir. Easy, not for the puritans, but the BX hasn't enough status yet to have it kept all "original". Hardest bit is refitting the front height corrector pipe,, once this is done its a worthwhile mod to get the return hoses up into the engine bay where they can be better managed..
