  1. You can check the drums by just spinning the wheels when off the ground, pull the handbrake on a little and they should rub all the way round. Almost certainly there will be a high point or two as cast iron drums are notorious for going out of true over the years but has to be excessive to affect braking. Have you changed any brake system components recently?

  2. I take it your clutch is fully disengaging and engine tick over is as low as possible? Certainly you cant change gear like a modern and Ive practiced to get mine as smooth as possible (matching revs, not too fast, not too slow etc) with different techniques for each gear and of course up and down. My box is still pretty good and Im putting off stripping it as long as possible but in the meantime have collected several others (as I say other versions have many of the same parts). Unfortunately some of the pattern parts available these days can be unreliable but there is a couple of rebuild specialists used on here that have a good reputation...

  3. I have the same set up and our gearbox, as standard, does have synchro on 1st. The earlier 1600cc cars didnt and first gear is a bit noisier to engage on the move...

    Unfortunately the synchro rings themselves are the same as used in the first 998cc Heralds so second and third especially suffer. This problem was reduced later with bigger rings in the last GT6/Dolomite 1850 and for this reason these gearboxes are highly sought after.

    Its a complete stripdown of the gearbox to replace the rings but with a bit of mechanical knowledge can be done at home. Mine is coming up to it but has managed over 80k on the original rings although I do drive pretty sedately and keep it in 4th as much as possible. However with the torque and smooth running of the six I dont find this at all difficult☺️

    Probably. A real solid molasses-like goo that blocks the free space round the pistons so that you can raise enough compression to start. I've no idea where it goes after that.

    No, my stuff was supposed to be a permanent fix that set solid to give you the next size up pistons and rings without having to strip the engine. Surprisingly it didnt make the slightest difference and the engine remained knackered😌

  5. Resistance plugs seem to be ok for modern engine manufacturers who you'd think would find an alternative if there was a reduction in ignition/combustion efficiency.

    Thats not to say they dont make a difference in older design engines but without some controlled testing on each model who's to say....  

  6. Colin there is indeed a spacer. It goes on first sliding over the key, up against the bearing inner race. Then the fan goes on with the blades facing the dynamo and positively located on the key. Finally the pulley the right way round so that the nut and washer clamp the whole lot in place...

    Thanks for the information, very helpful. I looked on ebay last night and noticed that the Chinese one's I saw at £89 a few weeks ago are now priced at  £229!

    Have gone up but still on ebay at 109 (or best offer) delivered...
