    That is interesting then. Perhaps mine is a 3-main as well. I haven't yet done a service on it but will hopefully get that done next week. I'm just waiting on a new set of radiator hoses. I'll have a closer look at it and find the engine number etc when doing the service.

    I bought it sight-unseen on EBay last week. It seems to go ok with new brakes although it has all the signs of being tired (Blows blue smoke and jumps out of second gear). I'm hoping to keep it limping around the farm in its current condition for the next two years or so before retiring it for a rebuild.

    Thanks for that advice John,

    Rohan.

    If it starts easily and does not use too much oil, I would tend not to worry too much about a bit of blue smoke. Possibly just the valve stem seals allowing oil into the intake. Not normally an issue with diesels as there is not much of a vacuum in the intake as there is no throttle. But this model has a throttle in the intake specifically to develop a reasonable vacuum for the power assisted braking, so that does not apply. If this is the case, replacing the stem seals is relatively easy and cheap.

    The jumping out of gear seems unfortunately to be fairly common with the Series 3 box. Draining the oil and inspecting what comes out may indicate whether it is the synchro springs. Less likely is lack of tension on the spring detents that hold the fork shafts in place. Unless this is the case, fixing it is likely to be fairly expensive if you don't do the work yourself, as the box will have to come out and be disassembled just to determine the problem.

    Thanks again for that advice also. I'm not concerned too much about oil consumption for the time being as it won't be going on-road at all. I actually have a spare series 3 gear box on the floor in the shed although its condition/history is unknown. I might run a rebuild kit through that and have it ready to swap once I get sick of holding the current one in second gear.

    I'll certainly look at replacing the stem seals though. Cheers.
