Threads are shagged basically, one idea is to machine the threaded section off and re thread plus a new top with a square on it.

Just cut the threads a bit deeper on the body and make a new top to suit, that would be the simplest option and most of it would still be original

Yes one of many possibilities, once the canopies and the raining of burning hot shite has stopped its the next item on the list stopping the oil rain ....

I am preferring the re-cut thread option I do like Davids idea of gluing the lid on and fitting a bung ... but I know somebodies going to unscrew the lid at the wrong time ...

When mine got to that stage we drilled and tapped a 1/4 BSP hole into the cap and fitted a pipe plug, then silver soldered a cross piece to the plug so it could be undone with your fingers. Easy and the old cap needs never to come off again. (You can loctite it on so a little heat will get it off if you need to).

Is the problem the thread on the central tube ,if so why not make up a new pipe,one way is to get length of brass hex ,put it in the lathe and drill a hole down the centre, and thread the ends, using hex allows the tube to be tightened with a socket spanner , most of these tubes have lots of mole grip marks where owners have tried to screw them in. Just made one this week for a Garrett.

How about solder the lid on? Means its a better fit but still reversible and someone shouldn't be able to unscrew it?
