Nice little detail to find.  Just a shame it's so faded...wonder if someone sells reproduction engine bay sticker sets for the W123...

If you can find someone online/local with one of those stickers in good clean condition, it would be astonishingly easy to get a replacement made up. A high-res photo of it in bright, even lighting would allow you to get an almost perfect reproduction. Worth a go.

Looks like for about £20 I can get a really good quality looking set of reproduction foil backed stickers for the whole car - which given that they are basically all missing or looking extremely dog eared may well be the road I end up going down.  Not making a decision on that yet though.

Gave the interior plastics a really quick wipe down this afternoon with some vinyl & rubber care solution.  Never ceases to amaze me how much life that alone can bring back to the interior of a car.

The interior really is a pleasant place to be.

Also gave a few of the exterior plastics a quick wipe down - totally forgetting the grey bit of the radiator grill.  Derp.

IMG_20210722_181757.thumb.jpg.d74dbc2e96e5d9f13bcd69da7c092549.jpg

Noticed while doing this that there's quite a bit of condensation in the nearside headlight.

IMG_20210722_181224.thumb.jpg.7a5fe32cf96256ddd6cb252af51094a8.jpg

So given how warm it currently is have just popped the rear cover off it, hoping the weather will dry it out for me.  I'll have a closer look to see if I can see any evidence of where water may have got in at a later date.

IMG_20210722_181503.thumb.jpg.2872155c784d16b350a9ecb6f599a9d2.jpg

May just renew the foam seal around the lens as a precaution if I can't find anything.  Looks easy enough to do at least.

Edit: Forgot to include a couple of photos from earlier in the day.  Really do feel that there aren't many cars which can match the sheer presence the W123 has on the road, not until you start getting into Rolls territory anyway.

IMG_20210722_152242.thumb.jpg.25b6425d8563dc7ee8e7749bbea6995a.jpg

Really does suit the estate shape I think too, quite a few estate variants can look quite clunky next to their saloon or hatch counterparts but this one just works.

Did notice one nice detail in the engine bay that I'll need to try to remake...you know all that technical info for servicing you're likely to need?  Spark plug type and gap, timing details, valve clearances...all right here on the slam panel.

Looks much smarter already. Try some boiled linseed oil on the driver's heel mat. That would finish it off nicely.

Haven't even vacuumed yet, the heel board will probably just get a decent clean.  Have to admit to a serious distrust of boiled lineed oil as it was responsible for one of our neighbours when I was five or so burning their garage to the ground...while I consciously know carelessness was the deciding factor (they were a bit of a clown) it's just something that sticks in my head.

Rocker cover gasket arrived this morning so should be able to look at getting the valve clearances set and the top end at least something resembling oil tight soon.  Then will get an oil and filter change done.

Not doing that beforehand as I'll probably want to clean things up after removing the petrified remains of the old seal etc so don't want to end up washing crud down into the sump if it's full of fresh oil.

Noticed the other day that one of the rear exhaust hangers weren't attached.

IMG_20210723_132115.thumb.jpg.a7d61372c7c2eafc851d36d106c26fb0.jpg

Upon reattaching this it became immediately apparent why - because the exhaust hits the bodywork with them both on because they're too short.

Cue horrible buzzing rattling noise as soon as the engine was started.

Solution?  Fit two new hangers which are slightly longer.  Problem solved.

IMG_20210723_153427.thumb.jpg.d63d990b372305c067b524bd92c00046.jpg

While in that corner I investigated the non functional reversing light.  Just a case of dirty contacts, after a quick clean it was back in action - though it needs a good clean and ideally a new lens.

IMG_20210723_155222.thumb.jpg.f28b712d28e86a96dd2e2d19411820db.jpg

Otherwise it's been a pretty frustratingly unproductive day.

Spontaneous combustion of rags used for applying linseed oil is well known to both wood finishers and cricketers.

I was warned on here about this spontaneous combustion risk just after I first used it. I had left a rag soaked in it in the garage so immediately ran out to check and was surprised to find that it felt significantly cooler than the ambient. Maybe I was just lucky, but I have had no problems with it at all.

I think the problem arises when the rags get put in sealed containers or bins, as some do to prevent the rags drying out.

Couple of things done today...first of which you wouldn't be able to see on camera - cleaning the inside and outside of the windscreen.  It's nice being able to see where I'm going now.  Inside was particularly bad with a really thick, greasy coating on it.

IMG_20210725_171712.thumb.jpg.71a1449b36ddffbbe8b2d37ba152c94d.jpg

Had a nose around under the bonnet with a view to seeing what I need to move to get the rocker cover off.  Doesn't look like it should be too bad.

Found a nut and a few washers so have replaced the missing nut on the exhaust manifold.

IMG_20210725_162639.thumb.jpg.62ba57bdb6a731292a6dd7c0f1cec3ca.jpg

You can see pretty well how much oil is everywhere.

IMG_20210725_165802.thumb.jpg.2198ff8f47a05f49d7698253010a5cc9.jpg

I am seriously looking forward to cleaning this engine bay.  Not only will it be immensely satisfying, but it will be really nice to not get covered in black grime every time I so much as walk within ten feet of it.

Spotted something that needed immediate attention today...this looks like it might be a vacuum leak.

453069568_IMG_20210725_1628032.thumb.jpg.f56f266048b4b71864fbddfcff3baed3.jpg

Yep...

IMG_20210725_170922.thumb.jpg.59bbd64be21dacf34f8d36d1478faee1.jpg

Found another one of these in a similar state over on the offside inner wing.  I don't have a diagram of the vacuum system yet so not actually sure what this does just now...

IMG_20210725_165050.thumb.jpg.666ed102946a7160f16975eb7d459b3e.jpg

I'll probably go around and change all of these boot connectors at some point as they're all a bit soft.

Speaking of rubber that needs changing, the supply line for the self leveling suspension is looking rather sorry for itself.

IMG_20210725_165805.thumb.jpg.fe98383af621e7eadc156eb254c625b3.jpg

Will look to get that changed soon.  I do need to confirm what type of fluid this uses - though the initial glance at Google seems to suggest that it's basically LHM with a Merc logo on.  Which would be nice as I've a load of that in stock.

Realised this afternoon that I'm going to need to spend more money before the proper cleaning can start though as my pressure washer died a couple of months ago.  This shows that she really needs a good clean...

IMG_20210725_161122.thumb.jpg.5e1e351fd06a237cf8c7084e31c5ebfa.jpg

I think one of the first  on mechanical issues will be seeing what I can do to straighten this out.

IMG_20210725_171153.thumb.jpg.58e1f1bfae5505dfe6cc6d79ef67555f.jpg

This panel needs to come out anyway for two reasons.  One is to replace the tailgate gas struts, the other is to fit rear speakers as there currently aren't any.

The moulding is basically fibreboard and I imagine has got wet at some point.  Hoping that with a bit of persuasion I might be able to get it to sit flat again.  Apparently getting this hooked back in place is a pig of a job so hopefully I'll only need to do it once.

Regarding that suspension hose - have a read around 1st before you touch it if it’s not actually leaking. I have a hazy memory of one being NLA but I can’t remember if it’s the one from the reservoir to the pump or the one from the pump.

I think it is LHM that it uses. That was about the only fluid that I didn’t change so god knows how long it’s been in there.

As an aside, it was also never particularly water tight in terms of cabin leaks,  so I’d recommend covering it if keeping it outside and not using it that often, when the weather changes.

Thanks for the heads up.  She's going to be in regular use so hopefully any water ingress issues will be tracked down reasonably quickly.

The hose is the intake from the tank to the pump.  Not too worried if the factory one is NLA as it's just a bit of generic hydraulic line at the end of the day - it's just a jubilee clip and barb connection at both ends so doesn't need to be anything special (beyond being resistant to mineral oil obviously).  The fluid does look pretty manky - it's definitely not the colour of LHM, but that doesn't mean anything.  It definitely *smells* like LHM. 

Noted when working on the exhaust manifold earlier that it looks like there has been some long term weeping going on in the vicinity of the brake master cylinder which hasn't done the paint down there any favours.  That's something which will definitely be cleaned up and an eye kept on.

on the subject of jet washers i'm thinking i may need to replace mine soon so i've been mooching- pro-kleens units look good value for money

I'm still somewhat undecided on what I'm going to go for here.  I'm probably going to end up going down the petrol route.  Either that or a Kranzle...though they're ****ing expensive.  Though if I did buy one it would probably outlive me.  It was the one tool that never, ever let us down at the garage despite much use and abuse.

I spent many years not having two pennies to rub together, trying to keep the cheapest bits of tat which someone else had already been thrown out by someone else.  We did honestly regularly have weeks where we had to  chose between putting £10 of fuel in the car or putting dinner on the table...which was a difficult compromise when the supermarket was 15 miles away.

Given we're in a halfway reasonable position these days I keep getting kicked by the rest of the family to actually buy half decent tools.  Not about to go full my garage with Snap-On kit, but the pressure washer is something I use quite a lot.  Wrangling the power cable and trying to keep it from getting tangled around either of the hoses annoys me more than just about anything on earth, hence my wish for either A: A petrol one to eliminate it, or B: A more professional one with a wicked long hose on the Lance so the pressure washer itself just stays put while I work.

If I came across an ideal engine I'd not say no to buying a pump head separately and making one...the little Briggs on our old mower wouldn't be a bad candidate aside from having a vertical shaft which is less than ideal.

Yes, I found out about the water ingress after it rained and left the front seats drenched but after thoroughly cleaning the sunroof drains out with compressed air it never leaked again.
We had torrential rain a few weeks ago and I'm happy to say there wasn't a drop of rain inside the cabin.

I never actually had it leak from the sunroof! Though clearly it had done before from the state of the headlining around it.

It was letting in water at the corners of the screen and from the bonnet hinge area, but I managed to get that about 75% stopped. I used to find if it had been sat, it was worse - if it moved regularly it didn’t seem to build up. So just keep using it!

Yep...we do have a fuel leak when the tank is fullish and the car is moving.

IMG_20210726_132341.thumb.jpg.878eae4ee821e69bc6aca44d01c702a9.jpg

It's not on the supply/return circuit, it's definitely just caused by fuel sloshing about.  I'll need to pull the floor out of the boot and see if we can see the gauge sender.  Hoping it's just the seal on that having failed as replacing that sounds way less hassle than dealing with a hole in the tank.

Tidied up the little storage compartment next to the fuel filler neck while I was peering in there to see if I could see any leakage around the neck.

IMG_20210726_133531.thumb.jpg.0d405bb285b89a3a81380e18658e18ae.jpg

Should be a warning triangle and a first aid kit in here too, I'll get those reinstated at some point.

Yet more Scotchlock connectors... they're all over this car.

IMG_20210726_133524.thumb.jpg.b87b61be03147213f4a27916730a3cd1.jpg

Wonder if this car had a tow bar fitted at some point in its life.

I changed out a hard pipe and fluid on the SLS system on a W210 wagon once.  The fluid is essentially LHM as I understand it but the Mercedes version is a clear colour.  It was eye-wateringly expensive as well so definitely use the green stuff if you have it in stock and it's compatible.

      What do you get after 16 hours and 800 miles of driving on a Sunday to collect two cars? Well @sharley17194 picks up a 1997 Citreon AX from the depths of the Lakes on the North West coast past Keswick. However, we actually started the day by driving to just near Cromer on the East coast to pick up this!
      An Austin Montego poverty spec estate with a 1.3L A-series engine! Yes you did read that bit right! Yes I know the DVLA lists the model as 1.6... Yes its correctly registered as 1.3L. No I dont know if its a factory 1.3L! 😂
      My favourite part of all this??? (Apart from the doom blue colour and the absolutely terrible interior!) 281,000 miles on the clock!
      Collection went really well and the below posts follows my initial assessment of what is quite frankly the best car I have ever purchased.

      Big thanks to Panhard65 for transporting this for me.


       
      Now unloaded and waiting for me to start work on it. First time I've seen it outside. I think Panhard65 thinks it's a bit of a turd but doesn't want to be nasty.

       
      Entertaining Mrs SiC friends today, so I need to put these away from kids hurting themselves. Going to live in the garden for a month undercover. If I can get the 1275 in there running, these will be sold on. If I can't, I'll see if I can get any of these in.

       
      For now, I have to earn some more goodwill credits with Mrs SiC.

      I bought a lovely Mini Cooper S from @Sunny Jim which my wife and I collected yesterday. See here:
      The Cooper made the 250 mile 4.5 hour journey to Buckinghamshire (from North Wales!) under its own steam but all was not well under the bonnet. The fresh air vents were providing anything but fresh air, I was choking on oily fumes. I stopped on route and wiped a lot of oil from the rocker cover and gently kept going, keeping the engine revs below 3k.
      Before you read any further, I have absolutely no qualms about the car or the deal I made with @Sunny Jim I bought an 18 year old car with 120k, sold as seen, of course there will be problems! 
      I investigated further this morning. There was oil all over the front of the engine and on top of the exhaust manifold shield.


      I went to remove plug lead No 2 and it came off in two pieces, the metal connector has split from the cable.

      Next I removed the sparkplugs. Plugs 1 and 4 were a little moist but plugs 2 and 3 were sinking in engine oil.


      The rocker cover gasket and plug well seals were obviously knackered, a typical R50/53 fault. 
      To get the rocket cover off...

      All this had to be removed. It's by no means a difficult job but it was time consuming. There is a bit more space under the bonnet of my W123 & W124!

      I've bought a new set of leads £18 and I'm picking up the gasket set tomorrow morning (£40). Hopefully the whole lot will go back together without any issues.
      Look at this engine, it's hard to believe that it's done 120k miles in 18 years. Everything under the rocker cover looks mint!

      In other news, to replace a blown brake light bulb I had to remove the entire light unit. How stupid. Modern* cars ehh?

      The annoying rattle from the tailgate was silenced with a 4 inch length of insulation tape, wrapped around the lock catch.

      I do like a clean exhaust pipe. Or two. Out came the Brasso and I am pleased with the shine.

      And finally, I've noticed that the small lights in the front bumper flick on randomly. According to the experts on a Facebook group, the presence of LED bulbs is upsetting the system.

      Been far too long* since I have done one of these..
       
      Last night, I spent some time ( and not an inconsiderable number of £) ordering up parts to fix 4 of the fleet. Additionally, the Audi goes in on Monday for two front tyres.
       
      By midnight I was cash poor and not yet part rich, so I downed the laptop and turned to idly browsing my phone..
       
      Staying strong through the sea of " for sale" tags here, I upped the ante and broke out TEH DADDY!
       
      Gumtree.
       
      Up in these parts, the bargains are oft far flung - population density and geography conspiring against the local bargain hunter.
       
      Due to this, my default search includes a radius of 150 miles - annoyingly flagging up NI cars not worth the extortionate repatriation costs.
       
      However, it also reaches into the far flung Ecosse.. catching exotic locations such as Duns and Huntly.
       
      But not so this time, for lo, the tree did bear fruit and it doth fall not far from my abode.
       
      This is the collection leg of the adventure, a TTT/ Split_Pin co-produced Caper.
       
      My lift arrives at 8.

      To mark the genesis of my fleet project thread I here present my new car: a 1997 Nissan Micra Shape-


      It really looks that good. There is a reason for this: its previous owner was an old lady who loved the thing so much so she made every effort to keep it in good shape. It originally came from Fleet in the GU postcode which suggests to me it was bought by the present dealer at auction, hence arriving down here in Kent. Before seeing the car I checked its MOT history and its only fails were thanks to broken stoplights, which shows me that it was very well cared for. I suppose an example of this was that on the last MOT, an advisory was a corroded rear silencer. The silencer on the car when I saw it was new. Methinks the lady wanted to keep it as good as possible. It was kept in a garage and so all the bumpers and black trim are very black and the tyres are in very good condition. Spare never used! Also included a free Dettol first aid kit from 1997.
      This car has 15000 genuine miles on the clock. We clocked over 15000 during the test drive! The lady owner really only trundled around her village in it and the MOT shows that it only did some meagre miles between tests. This, of course, came at a price. We saw a cherry red Micra from 2002 at the same dealer. Paint was shoddy and when they washed it the boot had massive sections of bare metal and it wasn't very happy. This car, however, is in fabulous condition and there was no contest between the two cars- it really is that good, inside and out. Immaculate interior, driver's airbag, cassette player... all there and all functioning (apart from cassette thanks to new battery and failed display). This meant that I bought it for £1600, £100 over what was my uppermost limit, but I knew I wouldn't see another like this that was in as good shape for a fair while. It was priced very ambitiously, at £1990, so I'm content in the fact I managed to slash a few hundred off the price. There wasn't that much paperwork though. All the dealership received was the logbook with 3 service stamps from 1998, 1999 and 2000, the radio key pass, a National Trust sticker, and the original paperwork holder. I suspect the old lady died and had her car auctioned, and the massive file of paperwork is now someone's egg carton, along will everything else she owned.

      As always, this car isn't exactly in showroom condition. While the inside is great and the floor is solid, and the underseal is in great shape, the not undersealed parts need a small looking at. Mainly the rear of the driver's side sill. It's really the only bubbling on the car. I suspect a well aimed stonechip managed to fester over the wintery salted roads, making it rust even more. It's around the size of a 5p piece, and will give me the opportunity to spray the insides of the sill with some chain oil to prevent any further corrosion. Behind the fuel tank there are a few rusty joints- places where the spraygun cannot get paint onto- which some Vactan and Dynax should put to rights. Alternator belt looks original because of the cracking and Nissan badges and will need doing soon as well as the front plate. As much as I like the 90's font and original dealer surround, the dishevelled R and general water ingress is a persistant MOT advisory. It could be the MOT station being strict (and most likely is considering there's a Saxo down the road with far worse blackening), however for the sake of peace of mind and all that, I'll get a new one made. The rear has already been replaced indicating this has happened before.
      All in all, I think this is a nice plucky motor. I'll have it by the end of the week; just got to sort out tax, insurance, and it's going to have an MOT. As part of the deal it's getting the MOT and an oil and filter change which will be something ticked off the list. It has some love scratches and chips here and there, but it drives well, is stiff and controllable, and should make out to be a nice summer project!
