Evening folks, time for another life of Tom update. You may recall that I've been doing a series of educational things for work, well I finished my exams on Friday and I CAN BE A REAL PERSON AGAIN! Saturday we celebrated by getting pissed drinking champagne for breakfast and lunch, then went to bed at 7pm because we were tired - daytime drinking for you! Sunday we spent in the garden, I unearthed the greenhouse from the jungle that is the bottom of the garden and put all the glass back in = one complete greenhouse! It took me the best part of the day, but glad it's done. We have some tomatoes and peppers that can go in there now, and we're experimenting with aubergines (moussaka) and cucumbers (gin) this year, so that's that.

The Kia Venga of dullness was moved on earlier this year, we (me!) wanted something a little bigger and more practical, certainly more *nice* so looking at all the criteria from me and Steve the onyl affordable option ended up being a Lexus RX 400h, It has a big boot, can do 40mpg if you try hard enough, goes like stink when it needs to and is 4WD (when grip/power is needed, separate electric motor at the back, itself giving out 70bhp in addition to the 3.3 V6 and the 170bhp front electric motor!) to help with the rural roads around where we live now, at least one of them regularly floods, so the ride height itself helps.

Image

Image

Also we got a dog last September, we were talking about it for a while and something local and nice turned up, so we got her! She is Steve's dog (mine to follow later this year...) called Tulip, she's 10 months old now, she's a Lurcher (dad collie, mum greyhound x saluki) and she is gorgeous! Not sure what we did with ourselves before we got a dog (probably quite a lot tbh...). This is her as a puyppy(ish), then in March (interrupted in having a good investigation of the Hearse's new engine), this is the most recent photo I have of her that I can get to now, she has grown and filled out a fair bit since but thankfully has stopped growing, or at least really slowed down.
Image

Image

Anyway, onto BXing! Today I went to see the GT and spent 2 hours fiddling, i'm working a night shift (right now, typing this in between work) so wanted to be home and in bed for 2pm to have a pre-shift sleep. I wanted to fix a little fuel leak from the fuel flow meter on top of the radiator top-mount (for the GT-only fuel computer 8) ) and look into the fuel flap that has never properly sealed, on the challenge fuel was splashing out of the flap on those mountain switchbacks! So that needs looking at.

Here they are, two BX's in a barn.
Image

Image

Image

The fuel leak was uneventful, just a split hose that I trimmed but I did notice all this coolant crystallisation! That needs looking at! The GT has always lost a tiny amount of coolant that I've either put down to 'old car' stuff, but perhaps there was a weep here all along? I think I replaced the thermostat back along and perhaps didn't seal it properly.

Image

The fuel flap was similarly easy, the insert to the flap that contains the lock and the sealing part was upside down! I hadf the french TRS to compare with thankfully to confirm my suspicions. There is a tab that fits into a cutout, but someone on this car had forced it into the spaces between the clip lugs that hold the the thing in. Unfortunately this had bowed out the plastic fuel flap slightly so we'll see how this gets on when the ol' girl is back in use.

You can see where the retaining lug/clips at 'north' of this insert are pushed out and bent.
Image

I gave it all a quick clean and wipe over whilst I was there, damn this car is nice! Not a spot of rust, although plenty of paint discolouration here.
Image

To finish I ran it for 15 mins so it got up to temperature, there was still enough coolant thankfully. It was quite nice really just sat in there making brum brum noises (me and the GT lol), I shuffled it about a bit too so the guy that rents the other end of the barn could get in and out easier, it still rolls and moves so that is a bonus! The TRS needs it's earths looking at (at least a new battery earth cable) as it would't turn over quick enough to start on the same good battery that started the GT in a couple of spins. Also need another battery, as I can't keep switching it around!

So what next? I'm hoping I can spend a couple of hours each week tinkering on them, I want to get the TRS running better so I can get the a/c in a better functional state before moving it across to the GT - that is the next job. Then I can move the TRS on and have more monies and space to do other GT jobs. Where they are stored is the other half's aunties farm, she sells her own produce (meat, dairy and eggs) on site and we do shop with her, so hopefully that justifies my trips there - it is only 5 minutes out of town anyway.

I am so glad I can get projects going again! There are many, and i'll have to split my time between house (new kitchen, boiler, decorating, re-wiring amongst others), garden (pond clearing, patio, finish shed, hot tub installation etc) and cars (two BX's, a Lexus and the Hearse). BUT It feels like we're getting somewhere in life now, work is going well (so far!), the house will be nice when its more 'done', the garden is getting there and the car situation is also on the up.

Until next time, Tom.

Well done Tom, dogs are awesome, we can’t imagine life without our little man, sadly he’s getting old and that’s a worry.

My GT hasn’t turned a wheel this year but will do soon.

I can remember when you had the inspector lady around for him Tim, seems like quite a while ago!

My GT has turned about 2 revolutions of a wheel I think, forward and back a bit :D

Phase 1 of the great aircon challenged has commenceth! I spent considerable time over in the barn today tinkering. My main aim was to sort the battery electrics and earths for the TRS so it started and ran better, I can report a full success here! I started fiddling, but got cross about the lack of access so removed the air filter housing, such a huge great thing on a MK1! Access now solved, I removed the battery to gearbox earth and battery negative lead and it really is no wonder that it struggled to turn over with such poor earths.

Rusty, frayed and split battery earth cable with it's *slightly* large replacement, I wasn't sure of the length required so went a bit OT!
Image

Battery negative lead was passable, but now much improved.
Image

Next issue was the gearbox top earth point, on removing the bolt the thread came out with it! So no good now, a different earth point is required.
Image

Not sure what this little guard, well - guards! But it was a convenient earth point once the metal was nicely cleaned up.
Image

There was an additional, small battery earth wire going from the negative lead to the body (inner wing), the new neg lead didn't have the facility to introduce additional leads, so I compressed the cable end between the two big spade connectors for now on the battery clamp. I will get another spade end - I didn't have any of this size with me, but it worked fine so hopefully will do for a bit.
Image

The GT got a new battery! I couldn't be doing with keeping swapping the battery from one BX to another... I have been very impressed with the GT's old battery, it has lasted ages and has been almost completely discharged a couple of times and not regularly run very much at all over the last 8 years, so I went for another Varta, but an upgraded one just because.
Image

I ran the TRS for a little while to it got upto temperature, it hasn't been run since last august so i'm sure it'll do it some good. I also wanted to shuffle it around a little so access to the barn was easier for the other tenant. I really could do with changing the oil, it's probably utter crap by now. I took a video which i'll attempt to upload tomorrow, a couple of observations:
-Black smoke when you rev it hard
-Had a couple of bubbles in the coolant after it was turned off (slightly concerning)
-Still hunts at idle
-After tapping the carb body with my hammer, the periodic stalling seems to have gone away (blocked float maybe?)
-Not running right still, after a bit of a rev it dies off and either stalls, or may idle.
-Exhaust sounds odd, I wonder if there is an obstruction somewhere.
-Tyres flat again!
-HP belt squeaky and irritating
-Turns over really quickly now the earths are sorted.
-No leaks!

So when it was in the correct position, up on axle stands she goes and remove a/c components-a-go! Wheel arch liner piece with compressor shield, nifty.
Image

Dryer, off. Will get a new one as this one is bound to be rubbish by now and they aren't hideously expensive.
Image

Oil coming out of the a/c hoses going into the expansion valve. Thought these lines should contain gas not oil! NB the amount of gas that came out when I disconnected the 1st hose was not even enough to disoldge the dead spider next to it, so no wonder the system was in/op.
Image

Lots and lots of swearing, clanging, adjustment of position (above, below, sideways etc) changing of tools and extensions later yielded this. A dissassembled engine bay a/c system (not the condensor, ran out of time), the worst parts were the two rear compressor bolts, they were very difficult to get to with averything else in the way (including the body of the compressor!). The a/c hoses were also on REALLY tight, even when the retaining nuts were removed the rubber seals took quite some effort so the hose could be removed.
Image

Does anyone have thoughts on re-using the hoses or having new ones made?

All tucked up again and time for home. I foolishly left the printed out wiring diagrams and technical bulletins at home, I had planned on checking the juice at each component to see what was/was not working. Ah well!

Hi Tom, those old hoses will be brittle by now and will anyway be much more porous than newer hoses. If you decide to get new ones then you could have two new charging valves fitted somewhere near the condenser and drier connections making access easier and keeping them away from road spray. The new hoses probably wont be cheap.
As the oil circulates around with the refrigerant its probably best to get it all flushed out before regassing, especially if it is still R12 mineral oil which is not compatible with the later R134a oil.
The Joy of BX with just one Citroën to my name now. Will I sing Bye Bye to my GTI or will it be Till death us do part.

The A/C system contains a measured quantity of oil, most lives in the compressor, but some circulates with the refrigerant and there is always some in each component, making it difficult to guess how much oil to add when recharging a system that has been drained or had parts replaced. Talk to your A/C tech, he may want everything flushed out, or he may want it left as-is.

If the A/C system was originally filled with R12 gas, it will need new charging ports or adaptors added for R134A. R134 leaks faster than R12, so it is recommended to have new hoses made.

I have had 4 old Jags converted over the years, on one I had new hoses made, no problem other than expense, the next I tried with the original hoses, but one was porous and you could just about see the oil oozing out through the rubber, I had a new hose made, but the fitter was a bit ham-fisted and broke the evaporator fitting, so that was a big waste of money. The next one I did not change the hoses and there were no leaks. The last I did had 1975 hoses and no leaks, but after a while a high pressure hose popped out of its crimped fitting. So you can take your chances.

Make sure you find a tech that has experience converting R12 systems so that he has the knowledge to use a compatible oil and calculate the correct gas charge weight. Even better if he has crimping tools for making up hoses.

Thanks for your replies and advice folks. I've organised a compressor service and conversion to R134a, not cheap! But better than putting an unknown unit on the car and spending ages tracking down faults.

I'm investigating how to get hold of new hoses, there isn't anyone obvious who's local to me, so I'd be grateful for any recommendations you learned chaps might have.

I had a thought today (ouch!) about the alternator and crank pullies, i wonder if these use a different belt? The a/c belt is ribbed and i have a sneaking suspicion that the GT's alternator belt isn't, as long as the alternator is good i suppose i could just swap these over. The crank pulley though...

Not sure when I'll next be up to tinker on the BX's, i might get a couple of hours this weekend but otherwise it'll be the following Sunday. Next week is looking very busy work wise and finishing with a night shift on Friday. I'll want to look at the condensor, radiator and fans next. I knew this was going to be a complicated project!
