Thanks Jonathan

Is it this one? That's from "CSR-SVR Cosworth 2300 - main loom" on Steve Marsh's brilliant CSR resources page. Jonathan

A bit more, please, Elie... can you replace the shaft without removing the box? Thanks Jonathan

Pretty sure blanking or unblanking the speedo drive can’t really be done in the car as it involves a gear shaft the width of the box. Ah... you can get to either side and fit the cap or the angle drive, but not the shaft? Jonathan

It's not a mistake, it's a widely used way of describing hardness because it can be caused by different species: Wikipedia"Why is water hardness measured in terms of CaCO3?" Jonathan

Very sorry to hear this. Where are you? Is this thread about that? I would attach pictures but am unsure if that is possible. It is. Start with the Forum User Guide and let us know if you get stuck. Jonathan

Thanks for the explanation. Jonathan

Thank you, Elie. 4 psi is about 2.7 m head of water or about 3.3 m of petrol. (Please can someone check this: Côtes du Rhône and a Mediterranean sunset seem to be optimised for something other than mental arithmetic.) ,,, There seem to be two possible causes: simultaneous faults in both carbs or insufficient fuel supply. At 3.23 m head you could rig a gravitational feed to the carbs and see if it all then works. Jonathan

:-) Please could everyone add prices (and sources) they've seen... and even paid. Jonathan PS: Even with cost that presentation of data shouldn't mislead anyone into thinking that it includes everything needed to make a decision. Lithium batteries are very light and very interesting. I wouldn't use any unsealed battery including the default Banner.

What's the typical pressure of the fuel arriving at the carbs in a set-up like this? Jonathan

When I had this discussion they weren't on the website but they were orderable! Jonathan

Have you got a model number or similar for your current sender? Does it have a telltale light? ... You can get an electronic sender which attaches to the mechanical drive from a Type 9 box. But it might or might not work with your instrument. ... Isn't it usually possible to change the drive without removing the gearbox? Jonathan

Ah, that's different, and not just potentially. I wouldn't have any reluctance in replacing it before you're caught out somewhere inconvenient, Jonathan

Battery was inadvertently drained, from which I believe full recovery is impossible... I've had car batteries that I couldn't wake up with a smart conditioning charger such as your CTEK but which later returned to active service. In order of preference I'd try: A big boy's charger/ jump pack at a garage or car electrician's.A traditional dumb charger overnight.Jumping it in parallel with a good battery and leaving it connected to a running alternator.I'm a bit uncomfortable about ECR's method but I'm not sure why, especially as I've just recommended 3! Jonathan

Yes, please. Private Message sent. Jonathan

No display at all now? Not erratic? Not working at low speed but failing at higher? No fuses blown? Have you got the wiring diagram? There's a lot of previous discussion, and I'd start here. How about jacking it up and checking: Condition of wiring and connections.The live feed and earth.Whether the telltale light flashes when you rotate the wheel by hand.Sensor gap?Jonathan

As above. It would be nice to do this using the factory or "standard" wiring colours.. Jonathan

Toxicology and thermal capacity discussed earlier, and probably not contentious. Thermal transfer is. Evans say that engines will run hotter but add that their product avoids local boiling. I'm not aware of any evidence that that occurs in the engine systems under consideration. ... http://www.veoliawatertech.com/crownsolutions/ressources/documents/2/21823,Glycol.pdf Interesting pont about water quality Water Quality: High quality water will help maintain system efficiency and prolong glycol fluid life. Recommended water characteristics include: Less than 50 ppm calcium (as CaCO3), Less than 50 ppm magnesium (as CaCO3), Less than 100 ppm total hardness (as CaCO3), Less than 25 ppm chloride (as CaCO3), and Less than 25 ppm sulfate (as CaCO3). That is interesting, and I'd often wondered about it. I use premixed coolant. ... But accidental poisoning and DIY dilution are connected. One of the ways that children (and possibly adults) get poisoned by antifreeze is by drinking the leftover bit from eg a drinks bottle that has been used to do the diluting: looks like a drinks bottle, no safety cap, brightly coloured, sweet... and you only need to ingest a small volume to cause problems. Jonathan

The test is not totally definitive But it’s simple. Thanks Jonathan

I would expect more replies to those two survey questions... You didn't ask why Members don't use Evans Waterless Coolant... Jonathan

... re corrosion protection, propylene glycol seems to be the best What studies have you found that show that? Thanks Jonathan
