All torqued up.

I see no smoke at tickover either. Quick blat around the block, only a few whisps of smoke on acceleration. I really hope this is it. Goes back to the garage tomorrow for MoT over the weekend or Monday.

well done chap! Worth the battles 

Indeed it was.

The garage was pretty impressed with my work as I'd asked them just to check the torques on all the fittings I had replaced before they sent it round for the test. Not blowing my own trumpet.

It's funny how different garages pick up different things. The NS suspension arm is barely noticeable by all accounts so may last the year out, the rest can be sorted as and when.

I'm now giving it a blez up to Kent for a couple of days. Then next Sunday the Corolla's balls get replaced, so another thread on some genuine shite to update!

Result of blat to Kent. Bit flat because bad connection to swirl flap motor (I know this is broken wire) so power is a bit hit and miss.

Just a smidge under 60mpg is best i’ve ever had coming up to kent. Happeh

With a year's ticket and a 200 mile shakedown over the last couple of days, time for a new list of jobs to do on this car over the next year.

  1. Full service including alternator belt, cam belt and water pump.
  2. Replace bottom engine pulley as I think the rubber damper in the middle of it is getting a bit knackered after 205 and it seems to vibrate a little.
  3. Sort our O/S wing repeater - the lens is cracked and mouldy, and the bulb holder is a bit grotty and has a iffy connection somewhere
  4. Check swirl flap motor connector and wiring, I think it has a broken wire or a poor connection; failing that reinstate old swirl flap motor.
  5. Replace both rear tyres - I may put the 2 y/o fronts on the back as they're about 3-4mm tread.
  6. Replace leaking headlamp washer pump
  7. Replace rear wiper blade
  8. Clear any codes that may have picked up
  9. Replace rear number plate bulbs (I have 2x 5w capless, but I'm looking at replacing with LED)
  10. Keep an eye on the rear suspension bushes and the steering inner joints as advised at MoT
  11. Replace any missing trims.
  12. Replace O/S/F front hub (that will be a mission as the driveshaft splines are still seized/rusted into it)

I'm hoping now with all the work I've done the car will be on the road for a few more years yet, if I can get her to 250k in my ownership I'll be chuffed. Going to take a few days away from car tinkering, plus the Corolla's MoT is higher priority now.

Mrs_d used the Saab this evening to go to her new evening job.

Got a phone call at 9:15ish from her telling me the car conked out. I knew it was low(ish) on fuel, about half a gallon left in the tank but she promised to put some diesel in on the way home. Went to petrol station with jerry can. Found mrs_d, and the Saab, and a puddle of diesel on the floor.

Cylinder No.3 has spat out its leak off t-piece again. Bodged it to get home but I'll have to assess the damage (if any) tomorrow.

I had the Corolla destined for some garage action tomorrow. Pah.

Did you put a new leak off kit on? If so, wondering if the engine cover maybe is knocking it somehow?

I assume all the mounts are still on it? The cover on the one I had was on+off so many times with the car breaking, I gave up putting it back on! A bit noiser (because its there for acoustic reasons too) but not excessive.

New leak off connectors and hoses, I think I still have a good T-shaped one from the old set. It had actually come out of the injector, so wondering if the O-ring or R-clip are wanky.

cover has its 4 rubber mounts so i’ll check make sure everything is in place. On Tacho break at work so won’t know until I get home and have a look

A smoll drive around yesterday evening and the diesel leak from No3 injector leak off system has returned. It's only a drip as opposed to pissing everywhere but nevertheless I don't want my car dripping fuel everywhere, especially as I have seen the mess diesel spills, unexpected rain or damp and motorcycles make when combined. It appears to be coming from where the hose and t-piece join, so I'm hoping it's just the hose being less than perfect as opposed to another t-piece being needed. I have spare hose but need to order more t-pieces, so I may get a set of the brass ones I have seen on the Bay of E, which means I can also jubilee clip the leak off hoses to them as opposed to interference fit with the plastic ones.

Can't do much with it today as I'm off to see my dad for his birthday!

I replaced the small piece of hose on injector number 3 and the leak went.

After a short drive, injector number 2's leak off popped out. Exactly the same issue as last Thursday - the R-clip has slipped and the T-connector jumped out. I noticed that Injector No 4's clip wasn't where is should be.

As posted in Ask a shiter? have I got crap R-clips or is something more serious the issue?

What about creative use of zip ties to hold the T connectors down? Does sound like the r-clips are a bit pants if they're coming off. Tried squidging them to close them up a bit and make a tighter fit?

I think it's a mix of poor quality R-clips and t connectors, despite them being GM branded parts. Well, they came in GM packaging. I'm hoping where I've changed all 4 o-rings and squeezed the clips a little they are holding today. Fitter at work owes me a favour so he's going to peek under the lid tomorrow see if I've done anything wrong as he knows these engines pretty good as we have a couple Fiat vans with the 8v version of the engine.

I'm hoping I've sorted out the injector leak off problems on this old crate now. After a new set of retaining clips proved to be as much use as a chocolate teapot, I bought another set, this time from a Saab Specialist on eBay for £4 posted.

Spot the difference. The new ones are a much better fit, but No 3 injector's leak off was still dribbling. This is the one I'd replaced the o-ring on a week ago.

Luckily I had managed to not throw out the old leak off connectors so I just whacked these back in with new o-rings from a jumbo pack I got from Lidl last summer (last 2) and they are snug, don't rattle about and no moar leeks by the looks of it. I am still tempted to get a set of metal connectors. Hopefully next month water pump, cam belt and alternator belt. Which I'm sure will be fun.

The hoses between the central T-piece and the connections on 3 & 4 are the replacement parts that, despite being GM 'genuine' parts, are utter shit (lower 2 injectors). I swapped the replacement hoses for 1 & 2 for the good originals that were in the garage in an old margarine tub.

      Hot on the heels of last week’s collectioneering of a Xantia, another collection starts here and now. Well it is probably a collection as long as the car is as described, but I am optimistic.

      Clues. It’s enormous yet quite cramped. Never had one before and it could be considered blessed, saintly even!

      First some background:
      I was brought up with no car interest, a car was transport and nothing more which resulted in a selection of poor cheap cars being the cars of my youth.
       
      Fast forward many years (just over 9 years ago) and I have a wonderful* Vauxhall Vectra estate to carry us about. Unfortunately it is crap and throws fault codes at us with nothing being there when it is checked (even at Vauxhall)
       
      As Mrs T is the main pilot of this chariot with the two little miss T's on board, it has to go.
      The hunt is on for the new steed to safely and comfortably carry the family around. I have a company car at the time so big journeys are not an issue.
       
      ebay is my weapon of choice to find the new family car. It has to be good value cheap for no other reason than I am tight.
       
      Weeks of research with lots of cars that are too expensive and too far away for easy collection end up in my watch list.
      Finally a possible is spotted in Fife. I go and have a look and find a poor looking but solid car. One previous owner and lots of history.
       
      The auction was to end on the Saturday at midday, we were going to be out! I decided on how much I was willing to gamble on it and on the Saturday morning I put in my max bid but straight away it went to my max bid, I was winning but it had three hours to go with no room for me to go up! We went out anyway.
       
      I spent the next three hours kicking myself for not bidding more while we were out as it was the first car I had seen that fitted my criteria. Fate was in charge.
       
      On returning home I go straight on ebay to find 'Congratulations.............'
      For the grand total of £500 I had just won this fine vehicle!
       

       
      It has 5 months MOT and after fitting seat belts in the rear for the girls car seats it is pushed into daily service.
      My gamble and subsequent use results in a perfectly reliable car that actually does what it is supposed to do.
       
      Even more importantly Mrs T loves it so a win all round.
       
      All my cars have names (most are earned over a bit of time) and this one is called 'Gwendolen' ( G reg car and from Wales originally. I hate the name but I am not going to argue)
       
      That sums up part one, more will be along later (probably much later)

      Hi all, new to the forum.  Thought you might be interested in what I've got myself into
      I'd been after my first classic car for a while.  If it's big and made in the 70s I'm interested.  Looked at few things like P6s, Zodiacs, Victors, SD1s and various other things.  Problem was I didn't want to spend a boatload of money on something that looked alright but underneath was actually a total heap.  The solution was to buy a complete heap in the first place and spend the money fixing it.
      So in January I went ahead and bought this from a colleague at work who was moving away and needed to get shot of it.

      It's a part finished restoration (I prefer not started) and it needs a whole load of help if it's going to stand any chance of using a road again.
      Pros
      It's right up my street.  Granada Coupes are quite odd and certainly stand out from the norm.
      It still has the original engine, box, interior and most trim.
      It came with loads of panels I need to repair it (mostly original Ford stock).
      It came with so many spares I could probably build a few Granadas and still have stuff left over.
      It was cheap.
      Cons
      Most of the front end has been cut off.
      Most of the body structure is quite rotten.
      It's going to take me ages.
      I work at a restoration company and my boss kindly allows me to keep the car there.  So I've got access to all the gear I need to restore it.  I've been busy on the car for a while now so will post more pics over the coming days.
      Cheers
