    Well, it appears I didn't get as lucky as I'd hoped. (I should note, I've not run it since discovering that screw fell out.) I have one unhappy-looking exhaust valve. (Also, the oil was as diluted as expected. I got 20+ litres out, it stunk like petrol so badly that you could smell it six feet away.)



    Off comes the manifolds, starting with the two studs that hold the downpipe onto the manifold. Naturally, one nut came off as if it were still factory fresh, and the other just instantly sheared flush with the casting.



    Some more finagling and cussing got the carburettor off... (Note the studs holding the manifolds together have also been removed, I was hoping to remove just the one; but that's not how it works and, besides, the other would've just been in the way anyway.)




    And, thankfully, all the nuts came off the studs/bolts came sweetly out of the head to allow me to remove the manifold.



    Not as heavy as I'd expected, honestly.


    Unfortunately, it gets a bit worse from there. Some careful checking with a length of TIG rod around the diameter of the valve revealed no simple obstruction pinched between valve and seat, so either the valve is bent, or just seized in the valve-guide.

    I did get the valve to move slightly upwards via the very careful application of a little force, to nearly bring it close to its rest position, but it felt pretty horrible. There was a scraping/dragging sensation that comes from something being far too tight in a bore; I suspect that, at the very least, it's going to require a new valve and valve guide.

    *sighing a-plenty*

    An engine rebuild was already on the TODO list, but I was hoping to be able to carry on limping it across to the workshop under its own power so that I could do welding work. The engine is a project in and of itself, and I want to leave it until at least after the brakes are done before taking that on.

    And just to rub it in, I've been blocked in the compound by a heavily-vandalised & immobilised truck, so I can't even simply tow it across to the workshop to do any welding.

    I'll manage, somehow.

    Any sign of the missing screw yet?

    No sign of it yet, nope. I'll probably end up kneeling on it while working under the truck, or something...

    Have to try and see the positive in these situations, that valve needed something doing wherever the screw has gone. All that has happened, really, is the engine rebuild has moved a few places up the todo list

    If at first you dont succeed, get a bigger hammer........... avoid the disappointment and use the big hammer in the first place

    One Militant is not enough

    I'm not even moving it up the list, it can stay where it is until it gets it right. (Trying to keep the collection of loose parts down; so I really want to focus on getting the brakes back together, for now. Otherwise I'll have a heap of bits that I'll lose...)

    It's not a catastrophe, just a minor inconvenience along the way.
