Andy's awful autos: BX inspection time

Those patches are amazing, really well formed. I wouldn't have a chance at making such a nice job of that.

Cheers!

The shrinker and stretcher tools are used to form the front double curve of that panel then I welded it to a flat bit and dressed the welds back. They are very handy tools to have. First thing I made with them was an oversized gingerbread man cutter.

Some satin black, then the awful job of underseal. I hate underseal but as the car already had it it makes sense to give it a coat. 

undersealed and exhaust refitted and we are done (appart from the mudflap once the underseal has dried)

Correct sized* gingerbread cutter 👌

Some gorgeous fabrication repair skills on show here - very impressive.

To BXpected

Put this up on here

We appear to be leaking in a few places. 2 fairly sizable leaks. One from the rear height thingy. And one is leaking on the nearside and dripping from the subframe. 

Doesn't this just look like the stuff of nightmares!

its also leaking diesel, oil, engine and gearbox and possibly a tiny bit of coolant. 

screenwash looks fine tho, so thats a win!

Great to see you've found your shite fettling mojo @Andyrew

Yum.

The height corrector has a return connection check that first. If it's not that, repair kits are available.

If any metal pipe joints are leaking don't try and cure them by tightening (if they are reasonably tight already). It's not the tightness that makes the seal. Always use a flare spanner, the unions are fairly thin tubes, easily rounded off. New seals are less than £1.

Today the wee trabby left

Decided to take a look under the BX. It had left its mark overnight. Quite substantial it must be said.

Found a damaged low pressure return? 

Chucked some random clear pipe that was the right size on for now and will check if it's fixed it for now.

Today i Also learned that even if the cars on the deck there's alot of pressure maintained in the lines at the rear. 

Me earlier after undoing said line.

Did you undo the pressure release valve bolt on the pressure regulator ?

A union that's into the height corrector valve thingy

What I meant is that there's a way to release the hydraulic pressure by undoing a bolt on the pressure regulator (by the accumulator sphere, in the engine bay). That could have helped avoid your impromptu LHM shower !

Rear end seepage

With the bucket having a large amount of LHM in it this morning I figured I'd have a look at the rear end leak too. The culprit appearing to be this height corrector unit. 

Exhaust removed, 8mm flare nut spanner  and a short sharp love tap got the unions released nicely. As said above, releasing said pipe then caused me to be showered in LHM. 

Unit removed, end caps popped off and grime cleaned off.

Everything Cleaned, refitted to the car and nipped up. The split end boot got a smear of polyurethane sealant over the slit.

Ran the car and cycled the suspension multiple times and so far . . . 

Even if it does leak overnight I'll be happy if it's slowed the volume. Also I wanted to make sure the unit was in good enough shape to come appart.

Before working on any of the pressurised LHM systems on hydro-citroens, you should always undo the release bolt on the pressure regulator.  It's a 12mm head bolt that faces the offside wing on the pressure regulator (bolted to the front of the gearbox).  Doing so releases pressure back to the reservoir.  Also, putting the height control in "low" releases all the pressure in the suspension systems back to the reservoir.. you can get all the pressure out before releasing any unions.  Important, as the running pressure of the system is dangerously high.
