That's all the springs back on now. Next up is the rigamarole of setting the clearances.

That involves laying under the car, turning the flywheel by hand, getting up, looking at the position of the piston, making sure it's actually TDC and then setting the clearances.

Repeat x8

Meh, I think I'll set them approximately and then do them with the engine running. I need a proper set of go no go gauges but I can at least use the 11 and 13 thou' blades side by side.

Just had a good old catch up on this thread, and like many have said - wow, such impressive skillz!

I wish i had the patience to give such in depth consideration and attention to the details you have done with this car. Also, much want for one of these, such a cool vehicle.

Rusty Fairlane distraction out of the way, I plan on getting back to this and reassembling the engine. 

However, in the interim I am having naughty thoughts about fuel injection and electronic ignition.

Somebody stop me.

has anyone put megasquirt or similar onto anything like yours phil

 

No, because the Megasquirt folks haven't figured out siamesed intakes, stating impossibru with port fuel injection

What's that metal, crescent shaped thing on top of the dash binnacle?

That's a traffic light lens. 

From the driver's seat, with the sun visor fitted to the outside of the car it becomes very difficult to see overhead traffic lights (the norm here) without leaning forward a long way. The lens gives a very wide upward view, allowing traffic lights to be seen from a regular seated driving position.

Surely it would be possible with a throttle body setup?  That's literally just throwing a fine mist of fuel into the intake.  Skoda used a TBi system on the 135 Rapid, and I'm pretty sure that has siamesed ports. 

A lot of folks disparage TBi systems but they can work really well.  Bonus on an older car is it's pretty easy to disguise most stuff in the engine bay too.  Generally won't require any irreversible mods either, possibly exception being maybe needing to drill a hole to secure the crankshaft position sensor.

Probably the biggest headache you'd have there is simply the length of the inlet tract...though having said that the displacement is enough that the gas velocity is probably pretty high so fuel condensation in the inlet manifold probably wouldn't be a huge problem.

It's definitely not something I would dismiss if you want to use the car regularly rather than just take it to the odd show.  I can't imagine that carb letting it breathe particularly well anyway (not that a flathead is ever going to be exactly efficient in that department), so you probably would see an improvement in performance too.

That's part of the reason I am thinking about it- the intakes are very unequal length and the far end cylinders have a habit of leaning out at higher RPM. Having either an injector per port or a carburetor per port/2 ports would also work. That represents 550cc per cylinder.

 

The volume drawn is not huge in terms of CFM because the top speed of the engine is fairly low (3750 RPM) so a moderately small injector with a finer spray pattern would probably help. I was considering TBI because that would allow me to retain the hotspot but it doesn't address the runner lengths. From the port itself the Y split is visible so having an injector underneath pointing upwards towards it should work well enough (likely better than the carburetor).

Interesting to see that (while the actual illumination source is different) that your heater/ventilation controls use the same sort of "floating" illuminated text as Jag did for the HVAC and ancillary controls in the XJS (and early XJ6/12 I think).

Yours are lit rather more usefully though!

Yes. A single 3 watt bulb that illuminates a sheet of acrylic mostly edge-on, with the words cast in to the sheet, and the backs painted black and the text painted white.

The principle is sound and still used today, though nice thick plastic makes it look "jeweled", which is really pleasing to look at both illuminated internally and from an external light source.

A straight 8 on ITB’s would be rather wonderful...

With equal length exhaust headers, correctly tuned- it would sound just like two 4-cylinder engines running beside each other...

I plumbed in the wipers and washer bottle. The seals have shrunk and it all doesn't work very well again.  

We'll see how long it lasts before I sack it off and install electrical wipers and washer pump...

      Well I've been meaning to sign up here in forever, but kept forgetting. Thanks to someone over on another forum I frequent poking me about it recently the subject was forced back into my very brief attention span for long enough to get me to act on the instruction.

      I figure that my little varied fleet might bring you lot some amusement...

      So...we've got:

      1993 Lada Riva 1.5E Estate (now fuel injected, as I reckon the later cars should have been from the factory...).
      1989 Saab 900i Automatic.
      1987 Skoda 120LX 21st Anniversary Special Edition.
      1985 Sinclair C5.
      2009 Peugeot 107 Verve.

      Now getting the photos together has taken me far longer than I'd expected...so you're gonna get a couple of photos of each car for now, and I'll come back with some more information tomorrow when I've got a bit more time...

      Firstly...The Lada. Before anyone asks - in response to the single question I get asked about this car: No, it is not for sale. Took me 13 years and my father's inheritance to find the thing.


      Yes, it's got the usual rusty wings...Hoping that will be resolved in the next couple of months.

       






      Next, a proper old Saab. One of the very last 8 valve cars apparently, and all the better for it. I've driven two 16v autos and they were horrible - the auto box works sooooo much better with the torque curve of the 8 valve engine. Just wish it had an overdrive for motorway cruising...









      Next up a *real* Skoda...back when they put the engine where it belongs, right out the back. In the best possible colour of course...eye-searingly bright orange.







      Seat covers have been added since that photo was taken as it suffers from the usual rotting seat cloth problem that affects virtually all Estelles.

      Then we have possibly the world's scruffiest Sinclair C5...



      Realised when looking for this that I really need to get some more photos of the thing...I use it often enough after all! We have a dog who's half husky, so this is a really good way of getting him some exercise.

      Finally - again, I really need to take more photos of - we have the little Pug 107.



      Included for the sake of variety even if it's a bit mainstream! First (and probably to be the only) new car I've bought, and has been a cracking little motor and has asked for very little in return for putting up with nearly three years of Oxford-Milton Keynes commuter traffic, before finally escaping that fate when my housemate moved to a new job. Now it doesn't do many miles and is my default car for "when I've managed to break everything else."

      I'll fill in some more details tomorrow - I warn you though that I do tend to ramble...

      Oooops I did it again......was a song produced two years after this automobile. I told myself ages ago that I’d thin the fleet down and cut down spending ...... it didn’t last long. If this new purchase is a worthy keeper then I may part with the 50 quid omega. But let’s not be hasty yet!
       
      transport steed of choice is my 05 discovery and a trailer, no pics yet as it’s still pitch black outside. 
      Poo count = 1
      Blood sugar level = 11.2
      distance to go = 88 miles
      setting off at 7, keep posted for updates.

      Place holder for some fun tomorrow.
      A free car ...but as we all know, that's a very untrue statement! This one has been sat for about a year and half or two. It was last MOT'd in 2017 but has been passing over the last few times with no advisories. 
      Two stages to this collection. First is getting the bugger running and the second is getting it home & MOT'd. 
      Tomorrow will be about hopefully getting it started and out of the garage. If this succeeds I'll then see about having it recovered back to either home or directly to my friendly local garage and have it tested. 
      Not sure how I'll do this - maybe do a single shot video of startup?

      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
