1987 Citroen BX

Recommended Posts

Today has been a good BX day.  Not only has the parts I ordered for the pump now being despatched, one of our neighbours asked if I'd like some old metal ramps.  I'm not a big fan of the old metal ramps for driving onto, I've had a habit once too often of driving a bit too far because I've no sense of where they are.  However, they are a practical thing to jack the car up and sit on for some jobs and free is free.  Neighbours were having a bit of a clearout and I'm sure I've become Old Car Guy (tm) on our street now because if people are getting rid of things, they ask if we'd like them, and I often do because it's useful stuff that we just don't have.

One of the most useful things was an old Black & Decker DN54 circular saw.  We've been clearing a lot of overgrown stuff out of the garden, old laminate flooring, and bits of fence and we've needed something to chop them down with.  Current pandemic restrictions means getting a tool we don't have hasn't really been viable, so providing this little saw actually works it should go through what we need to clear fairly quickly.  I'm guessing it's no newer than mid 90s.



We also got a bunch of old hand saws, some with those really comfortable wooden handles.  I'll clean these up and make them good again, these will be very useful dealing with garden waste that the circular saw and other tools aren't.  There's also a shed to build and the garage to kit out with cupboards and shelves, so these should be a real boon, there's even a nice little tenon saw amongst this bunch.


A Colortune 500 is a useful thing to have.  Am I going to resist the urge to put the Colortune sticker in the back window of the Princess?  Probably not.  It will certainly help with setting things up providing it's all present and correct, which it looks to be.


This little tool is an oddity.  It has two crocodile clips that go on battery terminals and it's for cleaning up spark plugs.  I thought they'd stopped making these well before this style of plastic bodied thing.  I'm thinking it can probably be repurposed as a bolt thread cleaner, I doubt I'll ever use it for its intended purpose.  I imagine the abrasive material inside it is full of lovely lead from old 4 star fuel.  Mmmm carcinolicious!


Finally, the sturdy ramps.  These should make some of the jobs I have to do at home a bit easier.  Jacking the BX up to get them under the front wheels was a bit of a palaver involving two jacks since without the injection pump fitted I can't actually start the car to raise the suspension, or drive the car onto the ramps.  It's another weapon in the toolchest at least and it's saved me getting a new set since there's nothing wrong with these aside from maybe benefitting from a coat of paint.


All in all, not a bad haul.

Late 70s/early 80s I would say - my Dad had one when I was a small child. I recall it being present when we moved house in 1984, but was too young to remember him buying it, which ties the date down to roughly then.

Happy days, the new pump parts arrived!  They're even correct, so that's nice.  I used https://injectionpumps.co.uk and can't fault them.


Unfortunately, I've come unstuck.  To save me going from garage to house I brought the pump indoors, surprisingly it doesn't really smell of diesel now.  I've got the throttle spindle, o-ring, and governer spring assembly all assembled correctly as far as I'm aware.  The problem is, every time I line everything up and go to put the lid on, I can feel that something is stopping the lid lining up.  I'm not forcing this for fear of breaking internal components again.


The larger black lever (for want of a better term) on the top right of the internals is I think what's stopping the lid sitting down.  Of the two levers, the one the spring assembly goes into is the weaker and much easier to move, the larger lever is very difficult to move.  I suspect the larger lever has sprung back against the side of the case and I need to push on it as I put the lid on somehow.




My other suspicion is that I've got the  black lever that goes in the top of the case misaligned.  I removed this when dismantling the pump, I probably didn't have to, and now I'm not sure which way or position it should go on reassembly. I'm concerned that if I get it wrong it will press on the throttle shaft fork and break it.


Advice sought on this one.  I feel like I'm really close to having this back together and it's my trepidation on getting it wrong that's the only thing stopping me.

Had another look at this and a couple of suggestions were to unscrew the bit in the lid that pushes against the large black lever.  This made no difference.  I looked at what else could be interfering and removed both the throttle shaft and the black lever in the lid, this allow the lid to close.  On trying the throttle shaft and the black lever in separately, without the other component, the lid will shut.

So, there's an interference issue between the large black lever in the lid, the the throttle shaft and spring assembly.  The parts are all undamaged, the new parts identical to what came out, I just can't figure out how they're all supposed to interact inside the pump.  I also can't find diagrams or instructions on this and I don't have any photographs because you can't really see how these parts interact when you're taking the pump apart until you have it apart.  May have to send this off for a rebuild yet, just to get the thing back in one piece.

A no-contact collection was done today for a BX bonnet for the I got for £20.  It's the wrong colour, and it's from a turbo model.  At the price, all I was hoping is that it was as straight and tidy as it looked in the photographs and happily, I was not disappointed.  On getting it home I first checked fit, which was good, and then set about swapping the insulation pads on the bonnet since they're different and I can't actually shut the bonnet with the turbo insulation pad fitted.  Very easy to remove, you just gently ease the pad over the metal clips that hold it against the bonnet.  If anyone needs this insulation pad it's yours if you can collect it from Kent, it would get destroyed if posted, I'm sure.


The pad from my old bonnet was transferred to the new one, which involved removing a lot of trim clips since the turbo pad needs more clips to hold it in place.



On the back of the original soundproof pad was this little hand-written sticker.  I left it in place, it was fairly firmly attached.


The silver bonnet does fit a lot better than the old white one, it isn't exhibiting the same signs of being twisted.  There is still an issue with the passenger side headlight area, which is mostly down to the lower outer peg the headlight pushes onto being loose and bent. This also means the headlight is pushed slightly too far to the middle and just touches the bonnet, which is annoying.


Other than that, the overall fit of the bonnet is much better and I could even get it to fit the hole evenly with the adjustment available at the bonnet latch, which I can't with the original white one.



In person, it's a big improvement over the other bonnet.  The main issue at the front is that wonky headlight now.  Did my best to line up a shot from my previous efforts to get the alignment correct and while there does appear to be a slightly lift to the silver bonnet over the headlight in the photo, it's mostly down to the way the headlight has drooped a lot more and the angle of the photograph with the car currently being on ramps because of the injector pump issue.  In person, it's quite a large improvement.  Alignment along the wings is much better too, without the big rise on one side and dip on the other.


I'd say that was £20 well spent.  Once I've got the car running again I'll see about getting this bonnet repainted and see if I can find some way of straightening out that headlight.

Had a go at installing the pump today and found out quite quickly that I couldn't do it.  For one thing, I don't have a dial indicator so I need to get one of those to set up the pump in relation to the engine so that the timing is correct.  However, that shouldn't stop me installing the pump itself, that should be a nice straight forward job.  The most difficult bit is getting the woodruff key slots lined up.  There's a slot in the pulley, like so.  Note one of the mounting studs is removed here, I'll come to that in a moment.


There's another slot on the pump shaft that goes through the pulley and bolts from the other side.


However, the two slots are misaligned quite a lot.  I didn't set the engine to TDC when I removed the pump because that wasn't in the instructions.  Rather, the engine was rotated to the point that the bolts could be put through the pulley and into the pump mounted plate which means you don't have to remove the timing belt, etc. and, in theory, makes for a quicker job if you're just dropping the old pump back on.  The problem here, is that I'm dropping what is effectively a new pump on and that's why there's this alignment issue.


I got one of the pump mounting studs out fairly easily, the other two don't want to budge.  My thought there was to line up the pump with the pulley without the studs and then rotate the pump to the correct position while the pulley was still locked which, in theory, should allow everything to line up nicely and I can then order the tool I need and be done.  However, because I can't get those two studs out with the tools at my disposal, this option is a no go.  Also, I can't figure out how to rotate the pump off the car to make the key slot line up, and I daren't force anything since I've only just forked out a considerable sum to get it made nice again.

Either way it's faff to fix.  I either need to get the tools to remove those two mounting studs so I can fit the pump in the wrong orientation and then rotate it to the correct orientation, or I can remove the timing belt and pump pulley, fit the pump and then fit the pulley to the pump, after which I'd have to make sure the timing was correct, etc.  Third option is to save up some more cash and just get someone else to do it which honestly, is my preference at this point.  I'm fed up of working on engines, I don't understand how anyone derives any joy from any of it.

Ok now I've seen the pic of the pump after you told me the problem on Telegram, I'd say get some plumbing pliers (or any pliers that open wide) and turn the shaft manually. Don't turn on the threads as it may damage them, but "technically" the only part of the shaft that's important is the woodruff key so you can scratch the shaft no problem as long as you don't gouge it like a barbarian. Try to turn it the way the engine would turn it, it's better for the pump, mechanical things generally don't like being turned backwards.

      What does £191 on eBay get you?
      An E36 BMW 316i with two sets of wheels, a DAB radio, an MOT until December, 110k miles on the clocks, a slightly* fucked back box and a bit of grot on the driver's side sill.






      This is co-owned between me and 17-Coffees and our plan is to do a light restoration and just generally piss about with it. It's actually really nice to drive, and is surprisingly brisk for only being a 1.6.
      Yes, the alloys are getting sacked off ASAP as it came with the original steel wheels with all-but-new Toyo Proxes on them!

      So many broken picture links!  I'll fix it one day.
      I feel I can finally unlurk properly now that I have something worthy of Autoshite to post about.

      Day One

      In the cold light of Day Two

      Came with some great features.

      The best thing about vinyl is that you *can* scrub it clean and with this old boat that was needed; everything was sticky and left a black residue on the hands. I've only been able to bring myself to spend an hour on the driver's door, the rest will have to wait for now.

      Doesn't look as big as it feels, weirdly.

      This is going to be my new daily in a few months, just got to get through a lot of cleaning and a bit of fettling. She's actually not that bad overall and only cost me £450 (plus £25 day insurance to collect her).

      The problems?
      >Quite a few rust blebs, but nothing serious or structural
      >Handbrake needs adjusting, I have to chock the wheels when parked on the drive
      >Driver's door window doesn't work
      >Probably decades of hand grease and silicone spray, built up in alternating layers. The engine bay is cleaner than the cabin.
      >Bonnet rams don't hold up the bonnet.
      >Neither do the boot rams.
      >Garage fitted electric fuel pump has no supressor, interferes with the LW/MW radio
      >PYE tape deck needs new belts, music played on it sounds like it's underwater
      >Bad previous respray with water contamination.

      But you know what, none of that matters. She's supremely comfortable and with some TLC over the summer should be in fine fettle. I'm not sure whether or not the people that look with face agog and jaw slack as I drive past are impressed, worried or amazed that a beige Princess with a brown roof still exists and is out on the road with someone a long way from pensionable age driving it.

      Well I've been meaning to sign up here in forever, but kept forgetting. Thanks to someone over on another forum I frequent poking me about it recently the subject was forced back into my very brief attention span for long enough to get me to act on the instruction.

      I figure that my little varied fleet might bring you lot some amusement...

      So...we've got:

      1993 Lada Riva 1.5E Estate (now fuel injected, as I reckon the later cars should have been from the factory...).
      1989 Saab 900i Automatic.
      1987 Skoda 120LX 21st Anniversary Special Edition.
      1985 Sinclair C5.
      2009 Peugeot 107 Verve.

      Now getting the photos together has taken me far longer than I'd expected...so you're gonna get a couple of photos of each car for now, and I'll come back with some more information tomorrow when I've got a bit more time...

      Firstly...The Lada. Before anyone asks - in response to the single question I get asked about this car: No, it is not for sale. Took me 13 years and my father's inheritance to find the thing.

      Yes, it's got the usual rusty wings...Hoping that will be resolved in the next couple of months.


      Next, a proper old Saab. One of the very last 8 valve cars apparently, and all the better for it. I've driven two 16v autos and they were horrible - the auto box works sooooo much better with the torque curve of the 8 valve engine. Just wish it had an overdrive for motorway cruising...

      Next up a *real* Skoda...back when they put the engine where it belongs, right out the back. In the best possible colour of course...eye-searingly bright orange.

      Seat covers have been added since that photo was taken as it suffers from the usual rotting seat cloth problem that affects virtually all Estelles.

      Then we have possibly the world's scruffiest Sinclair C5...

      Realised when looking for this that I really need to get some more photos of the thing...I use it often enough after all! We have a dog who's half husky, so this is a really good way of getting him some exercise.

      Finally - again, I really need to take more photos of - we have the little Pug 107.

      Included for the sake of variety even if it's a bit mainstream! First (and probably to be the only) new car I've bought, and has been a cracking little motor and has asked for very little in return for putting up with nearly three years of Oxford-Milton Keynes commuter traffic, before finally escaping that fate when my housemate moved to a new job. Now it doesn't do many miles and is my default car for "when I've managed to break everything else."

      I'll fill in some more details tomorrow - I warn you though that I do tend to ramble...
