Zel's Motoring Adventures...Jag, Citroen, Mercedes & AC Model 70 - 14/02 - Tracking Sorted...

Recommended Posts

Yeah, it's not going to be cheap.  Though it's a heavy and powerful car and tyres are probably the single most safety critical component on the car...so no Chinese Death Rings will be used here.

Will probably be a toss up between the Pirelli Cinturatos or Michelin XWX if I go for the "heritage" options, though I'm not married to that.  If there's a current design which ticks the boxes I'm happy to consider that too.  I'm not interested in concourse show points!  I'm also quite aware that modern tyres tend to have much stiffer sidewalls, and that there aren't going to be a huge amount of choice...so this may well be what I wind up with.

I knew full well that bills like this were to be expected when I picked up the keys to this car.  If I wasn't seeing it as a keeper I'd leave them be and be careful...but it's a car I'm enjoying driving, so it just needs to be done.

The fronts currently fitted are Corsas, which I'm pretty sure aren't particularly well regarded...even when not 17 years old!

The rears are "Winda" branded, which I've never heard of.  All I know is that they're comically slippery.

Had a run over to Banbury today and had a pretty clear road both ways.

Would this have any effect on my economy?

Yay!

Wait... that's still awful, but just *slightly* less awful!

You need to replace the trip computer with something a little more appropriate. Like this. See, same buttons.

Is a T rated tyre not 118 mph max speed?

Yep.  It should be wearing V or W rated tyres really - need to double check which between those it is.  Not that she will ever be travelling that fast...while I haven't checked with my current one, my previous insurer insisted on the tyres being speed rated as per when it left the factory.  This was really annoying as it basically doubled the price of the tyres I bought for my first Xantia.

Landsails aren't anything special but what I've heard they seem to be a perfectly acceptable "normal" tyre really.  Nothing special but they're not going to kill you the first time you encounter a corner.

On the tyres front it is an interesting one. That particular size is something you would find on a van these days. Plenty of options there, but the moment you specify the correct load and speed ratings, suddenly there are very few options. I was going to recommend Nankangs as a sort of good compromise. My XJR6 is happy on them.

Going to see what Formula 1 can offer.  Nankangs are on my possibility list definitely if they're available in the right size, a few folks have name dropped them so definitely will be considered.

If I do go down the specialist route, I've now added an additional possibility to the list as Vintage Tyres have Avon TurboSteels at the same sort of price as those mentioned yesterday...and those are kinda the go to choice for the likes of Rollers...and they'd definitely look the part.

Plus I've used them before and was really impressed with the service.

Will see what F1 come back with and go from there.

As mentioned previously elsewhere there was definite evidence of uneven tyre wear on the Jag.

Offside front:

IMG_20200214_140417.thumb.jpg.123ea679ca00a2bb8fe81adec51ef9cf.jpg

Nearside front:

IMG_20200214_140425.thumb.jpg.94aca3d2c4064150a4b9798b2ac9fdb0.jpg

Not as dramatic, but it's still definitely worn on the inner edge.  Also evidence of chunking in a few spots...these tyres need to be binned now.

Rears have plenty of tread left at least and there's no signs of any damage to the tread surface or perishing.

Offside:

IMG_20200214_140445.thumb.jpg.061e2e0074c19d3d08ee9d55820acf7c.jpg

Nearside:

IMG_20200214_140436.thumb.jpg.7c8965d6d9a4bfa664babb939c52c7ce.jpg

They still are only marginally more grippy in the wet than aerospace grade teflon however so aren't long for this world.

The steering wheel being off straight (which made indicating right a perpetual fight with the auto cancelling mechanism) and the fact that the car tramlines horribly on uneven surfaces (especially under braking) further suggested to me that the wheel alignment needed help.

Being a regular in the garage they were perfectly happy for me to have a wander around while they sorted the tracking.  This was useful as it allowed me to confirm where the exhaust is touching the body.

IMG_20200214_150050.thumb.jpg.591b8e0e0b040d0de6ed8f40a11f9ccc.jpg

IMG_20200214_150045.thumb.jpg.57f8a953a9149fd35d3d76c89d7e6517.jpg

That silencer is the guilty party.  It's about 1/8" away from the heat shield above it and any movement in the system makes it make contact.  As the tailpipe on that side sits a good 1" higher than the other side I reckon the rear hanger needs a tweak to just drop that whole lot a little.

I was also able to see that the rear gearbox mount looks almost brand new, so with a bit of luck I can not worry about changing that for a while.

The end result:

IMG_20200214_150222.thumb.jpg.1c28fdca6ef3cf11439cf978a6586059.jpg

Front toe adjustment is all we're interested here (everything else involves swapping shims I believe anyway).  Annoyingly I forgot to get a snap of the readings before we started.

Straight ahead is now indeed straight ahead.

IMG_20200214_165350.thumb.jpg.10080fc1fc704d6da7fc705c105d0c75.jpg

The disconcerting fidgety sensation has now left us which is nice. It was particularly bad before when you went over the white line while changing lanes on the dual carriageway for example.  Plus she now brakes in a straight line which is nice.  That required nearly Lada levels of correction when braking from speed before.  Hard to tell if it's just in my head, but it feels like it's now rolling more freely too...wonder if that will translate to any additional MPG...probably not!

A small adjustment which took maybe 20 minutes, but it's made the car a lot more pleasant to drive.

Not sure if they make the size you want, but my Astro van and my X308 Jag are both on Goodrides. I find them pretty horrible on small light cars but very good on heavy cars, to the extent I look for hem when buying for a heavy car. Cheap too.

There is something very satisfying about sitting in the warm, cozy back of a camper while the weather goes absolutely mental outside to the extent that the rain is running *up* the outside of the rear window rather than down.

IMG_20200215_162224.thumb.jpg.6084ef8cbdf04004416250583365d399.jpg

Only popped out to make sure it was staying dry inside and to tidy up a bit of stuff from the worktop that I'd been using as a workbench earlier in the week.

Of course I then lay down on the sofa to watch the weather for five minutes and woke up an hour and a half later...oops.

amusingly a couple weeks ago I was talking to the owner of MPH759P and he jokingly mentioned how he was thinking of fitting a set of such off road style tyres to his Model 70! (obviously much smaller in size!)

Hope they don't ever want to go over 30mph...chunky tyres like that have a lot heavier rolling resistance than the normal ones, with so limited power that will be really noticeable!

yeah! I just recommended he go with Camac BN313s! and to keep things stock

(especially as at first I thought he was planning on changing his wheels, so I told him at least keep the front wheel stock, as if you put a different wheel on the front and get the offset wrong, well your front wheel aint going to be on the center line anymore and gawd knows what that would do to the handling LOL)

as for speed he has had 65 (on stock tyres obviously) out of his, not bad going :) (although I don't know the circumstances ie if that was all his Model 70 had to give, or all his nerves had to give!) he says it drives really well and he and his is girl friend go out in on the weekends, at least during summer when the lack of a functioning heater is not an issue, so much for "passenger carrying is forbidden"! (he does at least have a bench seat fitted LOL)

Today when I got into the Jag and went to leave the drive it decanted a not insignificant amount of extremely cold water all over my feet.

I do believe I can see where it's coming in (or at least some of it).

IMG_20200216_151326.thumb.jpg.8472699b8e58ed384d6034244eb892f9.jpg

I suspect that there's probably some gunk in the scuttle drains too, so will look to get that checked out too.

Now things have dried up there's a clear mark where water has run down over the windscreen seal.

IMG_20200217_145714.thumb.jpg.7699decf76e150b86aebe7f5c9d1b578.jpg

This tends to make me think that the water has found its way in between the glass and the seal rather than the seal and the windscreen surround at least.  It's only a theory at this stage though.

Some of this stuff was deployed to hopefully find and seal the leak.

IMG_20200218_150955.thumb.jpg.cd51cc6398faa05ade3bca1edec48fa6.jpg

It's been years since I last used this stuff but I'm sure it's become more unruly... really struggled to get a small enough amount out of the bottle.  Maybe I've just become more clumsy, or the smaller bottles are just easier to manage.

While I had it out I also gave the windscreen seal on the Invacar a going over with it.  That's been about 90% watertight since I did some work on the seals but still leaked a little so hopefully this will help.

Next on my agenda was to see if there was anything I could do to silence the nearside exhaust.  My first port of call was to loosen the joins on either side of the rear silencer and rotate it a bit to try to get a little more clearance.  The hanger is attached to the outlet on the silencer body so this gives effectively about 3/4" movement either way.  While this has helped, it's not totally resolved it.  So I'll need to pull the silencer off and see if I can "convince" the hanger to give me a bit of extra reach.

While I was down by that corner though I did spot something else needing attention.

IMG_20200218_162843.thumb.jpg.305b6b583b884ab0bf68312b98995856.jpg

IMG_20200218_162833.thumb.jpg.a401080755210a217ee38421db4be6bd.jpg

I have a sneaking suspicion that if I start poking here I'll end up with a not insignificant hole.  To be fair it shouldn't be the end of the world to sort and it was inevitable I'd find a hole somewhere in a 35 year old Jag so I'm not hugely surprised.

Not faffing around with metalwork at this time of the year but I'll look to drown the area in Vactan etc in the near future to try to halt any further degradation in the near future.

Will I be able to resist the temptation of seeing what she sounds like without the rear silencers given I need to remove the one to mess with the hanger?  Not a chance!

saw your most recent post on microcar world @Zelandeth and it got me wondering

AFAIK the Hub on a Model 70 is a normal Fiat 500 (126?) hub just drilled for 4x4 inch PCD, and I was wondering, could you just get a normal Fiat hub then and send that off for machining?, which means you don't have to remove the existing hub, keeping TPA mobile :)

I would imagine Fiat 500 bits would be relatively plentiful? 

(nice to see TPA again btw :)

      Thought I should probably start a thread, given that a few people have suggested it. For my sins, my first car was a 1985 Hyundai Stellar. Bought back in 1997, when the sun still shone, I had more hair, and the world was generally a better place.
       
      This may be the earliest photo I have, I think from 1998:
       

       
      Anyway, I drove everywhere in it, and clocked up over 100k miles before I was given an Alfa Romeo 75. So I took the Stellar off the road for some much needed TLC. Made some progress on it - Rebuilt all the suspension, fitted a rebuilt Cortina* rear axle, Princess 4 pot front calipers and Capri vented discs etc - before a couple of house moves and renovations put it on the back burner.
       
      * before anyone says they are identical underneath, there are some differences. I fitted a replacement axle fairly early on in my ownership, only to fit that not only was the propshaft flange the wrong size, the UJ was totally different so I couldn't even fit a new yoke. Finding a company on the day before New Year's Eve who could cut off the end, weld a new UJ on and balance it wasn't too easy, especially one that was accessible by push bike!
       
      Anyway, late last year I found some renewed motivation, and have been working on it when time and money permit. Here is what it looked like in October:
       
       
      OMG barn find?

       
      Front suspension OK at first glance...
       

       
      ...but it has turned out the calipers had seized (so are away being rebuilt) and all the (brand new) ball joint boots had perished:

       
       
      Quite a bit of welding is needed too, but I had a setback just before Christmas when we were burgled and my welder stolen
       

       
      Crusty roof rail

       
      I've cleared some of the crap away from it now (it's not stored at mine - I'd love to own somewhere that big!) so might be able to get more photos. Currently working on the rear brakes, and disappointed to find that the shotblasted rear axle is now starting to rust after two coats of POR15 and 7 years storage under cover...

      Now, after thinking long and hard I have decided to try and part with this thing. The Great* BMW 635CSi. I bought this car from some dark shady place in Hackney and everything told me to walk away but in true shitter style I handed over the cash and drove it home. That was about 6 years ago.
       
      The plan was for it to be a rolling project but behind the scenes it was far worse than it looked and the bridge was looming. I took some weeks off work and tore it to pieces after taking it to fail an MOT. This showed me what I needed to do to get it legal after about 20 years of fudging it's way through life on bent tickets.
       
      Work done and it was used pretty much daily but it was a ticking time bomb waiting for all those 1980's parts to expire. Most of them did and were replaced accordingly. It's broke down twice. Once was a loose earth to the battery which was probably my fault and was so obvious that no one found it and the second time the main relay gave out.
       
      This car was my pride and joy and nothing would keep it from moving.
       

       
      ^ In it's prime*
       
      It's got plenty of character. It has a mind boggling electrical problem to do with the interior electrics which when I bought it involved having to remove the interior fuse under the bonnet to shut the engine down, and likewise the opposite to start it... not handy when refulling so I bunged a switch inside. It's now a safety feature.
      It's got a little knock when selecting reverse, it's always done it which tells me it's working.
       
      The bonnet, I removed no less than 12 coats of paint as it was chipping like a china plate. It is now in grey epoxy but the air flow meter blowing up dented it a little bit. Thanks.
       
      No BMW alarm anymore. The previous owner had this removed as it was thought to be causing the starting issues. The BMW wiring expert* consequently buggered up the cars electrics resulting in the above.
       
      ABS is disconnected as it was working at random. Never used ABS, don't know what it's for so it's left disconnected
       
      Heater valve has always been knackered. Blows fast hot only so that's never been looked at as it is considered to be working.
       
      I can live with these problems but then it developed more sinister issues:
       
      1) The rear half shaft undone itself but not completely
      2) the boot lock failed to work and had to be drilled out
      3) ignition issues resulting in 3 distributor caps.
      4) Air flow meter exploded one fine morning resulting in a total Motronic system check and overhaul where needed.
      5) The starter motor stopped starting the motor which was an absolute A hole to change.
      6) The most recent, the brakes all lock on when the engine gets hot.
      7) The fuel pressure regulator needs to be replaced. The car runs great on it but it can be improved. It causes a minor on/ off surge on fast straights in the summer.
       
      Problems I've caused.
       
      1) The ride height is too low
       
      Due to a complete career shift I had to give up my unit which was where miracles took place and weekly inspections and repairs could be done. The car was pressed into daily service, 100 miles a day for a few months or so until the brake problem became apparent, on the A14, in heavy traffic. Terribly embarrassing. 
       
      My career is very demanding and since May last year this car has been sat. I have no time usually and I hate seeing the thing stuck outside and it hates me for leaving it there. I have managed to get some time to do bits and have started to replace stuff on the master cylinder, pressure sphere ect but I don't know if this is the cure... which will just give me the arsehole if it isn't. I have also detected that the bulkhead seals and possibly the windscreen is letting water by. I removed the carpets and hey presto... I have some welding to do.
       
      So what's the future for it? 
       
      I don't like it anymore... it's beaten me down and without my unit, working on it is hard work (I also own a Land rover...) I have come to realise after a year or so that I can't afford the time and aggro with it anymore and I think that it's best to move it on. BUT I DON'T WANT TO!
       
      So, I'm am continuing to repair the mysterious brake issue in a bid to fix it and I'm going to weld er up and continue to try seek some enjoyment out of it like the good old days but in the meantime it's like having an anchor around my neck so if it sells, it sells.
       
      The good bits...
       
      1) The car is fast. Hit that sport switch and boot it. Nothing falls off and you stay in the same lane. Gives plenty of modernz a run for their money. That engine will gowan and on, it's been serviced when it's been due with only the best oil and proper plugs, compression tested too. I put a pipercross in it but thought it was shit so reverted to the standard filter.
      2) Decent HT leads
      3) Auto box had some work years ago totaling £1500! What?
      4) Most (about 85%) of the bushes are polybushes. Trailing arms need doing although there is no play with the current rubbery ones.
      5) Most 'messed about and lashed up by previous owner' stuff has been changed out.
      6) Rear tyres (cooper) are recent but I'm not happy with their performance in the wet pulling away as they can smoke and lose it like fcuk. The car suits dunlop sports well but I kept getting irrepairable punctures which gets expensive. The fronts are sports but are worn. Spare is original rim and tyre (good luck using that).
      7) Leather is in good nik with no rips. Drivers bolster is worn obviously but tarts up ok.
      Underside is well alright. I have pictures of all the bits that I done to it.
      9) Body paint is totally and utterly fucked because patina (shit paint job, laquer peel and fading). Ideally needs some panel rust dealing with and a blow over. I like it as it is... Looks street Yo.
      10) Heaps of paperwork, receipts, MOT'S, plans of action and diag test results all in a lever arch binder. Can get pictures on file too.
       
      The bits it'll ideally need soon:
       
      1) New suspension. You'll get the hump with the lowness. Working on it sucks.
      2) The sills have only another couple of years in them at a push.
      3) Brake backing plates. I've repaired them. The backs are holding out ok but the fronts are gonna vanish
      4) doors seals, sunroof seal
      5) back light seals and chrome. It's all fucked and can't be fixed.
      6) I'm putting on new front brakes as they got fried
      7) Probably a power steering pump as it whines sometimes when cold
       
      To make it ACE:
       
      1) All of the above but decent parts are becoming an absolute joke to get hold of. Walloth are catering more for these now but the 635 has been largely left out of the club.
       
      Here are some pictures took today after pushing it out of hibernation...
       

       

       

       

       

       

       

       

       

       

       

       

       
      So there... I've been honest, buy it for £NOT FORCED STALE and put me out of my misery. However, as I do want to sell it don't want to sell it, as I fix the thing and get it back on the road, the price will reflect that and probably will end up not being for sale.

If this new purchase is a worthy keeper then I may part with the 50 quid omega. But let’s not be hasty yet!
