    How old is your current oil? And do you know when the filter was last changed? Jonathan

    ... are you saying that it is unlikely that the oil pressure gauge and sensor are the cause the problem? I think so. The two common wiring faults are open circuits and shorts to earth. For circuits that work by varying resistance to earth neither of those should blow fuses. All corrections welcome. I've never played with an electronic speedo on a 7, which is why I asked about the general way they work. I know there's something about the sensors and wiring in the archives and I haven't found it yet. Jonathan PS: I like Garry's approach as a quick test.

    First thoughts while you're waiting: Do you have the relevant Assembly Guide or Handbook with the diagrams and fuse list? If not please send me a Private Mail with your email address. Do you have a meter already? (And lots of appropriate fuses.) Instrument circuits that vary resistance to earth shouldn't be able to do this. So I'd start with one of the others. How does the wiring work for gearbox and wheel speedos? Is there a live feed and a live-ish signal return. If so that sounds like a clever suggestion as 3 wouldn't apply. Does ChrisC's comment about losing the tacho apply to all models and ECUs? Any recent modifications or work "near" the affected parts?Jonathan

    Very interesting... but how much oil or water do you have to lose when swapping a sender? (Videos welcome!) Jonathan

    Back to basics: how about testing both senders in a rig with a thermometer? Kitchen, oven and cooking oil? Jonathan

    What sort of speedo and dash? Jonathan

    What sort of speedo and dash? All other electrics OK? Jonathan

    I'd talk to Simon Rogers at Meteor Motorsport. Jonathan PS: What sort of BMC engine, please?

    Well done. ... something to do with a bevel? Jonathan

    What's your sump clearance (and what would you like it to be?) and can you add a side photo? Jonathan
  11. Jonathan Kay
    Well done. Have you got an Assembly Guide with the note on adjusting the rear antiroll bar? (And do you want one?) If not please send me a Private Mail with your email address. Jonathan
  12. Jonathan Kay
    Can you add a photo? Jonathan
  13. Jonathan Kay
    I didn't understand this when I assembled mine, and I still don't. Does anyone have a diagram, please? Jonathan
  14. Jonathan Kay
    revilla's excellent analysis and diagrams are now in the Guides. I think he's also done parts lists and sources that will help. Jonathan
  15. Jonathan Kay
    You're doing well: I don't even try from a 'phone! :-) Jonathan

    Have to be careful to remember to lower the volume when reaching built up areas Thank you. I wish everyone else did. Jonathan PS: But I am surprised that anyone goes for speakers rather than earphones in a 7.

    ... but how do I post pics here again? You can now do it either by direct uploading or putting them on a server and linking to them. Ian B's Guide. Jonathan
  18. Jonathan Kay
    Well done. Jonathan
  19. Jonathan Kay
    How much lateral play can you get by unfixing the gearbox mount and loosening the engine mounts? Jonathan
  20. Jonathan Kay
    Have all the parcels arrived and has everyone got what they want? Let me know if not. Still a few of each type of bag available. And how about some photos of where they're fitted? Jonathan
  21. Jonathan Kay
    Thanks, Adrian. I think you're not alone with that description. Jonathan
  22. Jonathan Kay
    Did this get near establishing a Best Buy... or a Bulk Buy or Club Discount? Jonathan
  23. Jonathan Kay
    ... and in my view was the best road seven I've ever driven and that includes my current R500K which is nothing like as enjoyable on the road. That interesting suggestion again that lower powered 7s are more fun on the road. More details, please. Jonathan

    Caterham curves on dyno-plot. (This is the database to which DVA Power links.) Jonathan
  25. Jonathan Kay
    Which gearbox do you have? The peak power doesn't seem to be the key factor that you're trying to improve... this is a great opportunity to share some power curves... Jonathan
