AdeV:
There were only 2 possible locations this sump could leak: The plugs in the end of the long holes; and the spigots.

Sure enough, the spigots leaked, just a tiny bit, but in the interests of not leaving puddles of oil around the place, it required a fix.

The sump was duly returned yesterday, and today some machining was done...

The new spigots were turned from an old pin (aka, mystery steel). It turned like a 2 day old dog poo - i.e. it stunk. But carbide won in the end, and all 3 items were turned and threaded. Here's the last one, I've just finished cutting the hex in it. A 19mm spanner fits nicely:

Old and new. Notice the flange & O-ring on the new ones:

Finally, they were fitted & graunched into place:

The pattern on the top one is due to my machining the first one in the wrong order (doh). The chuck just wouldn't grip tightly enough to allow the 1/2" BSP die to cut the threads. In the end, I found that if I gripped on the flange/nut portion (before it was cut, obviously), there was enough grip to turn the die. The other two I turned the backside (threaded end) first, before drilling out the centre. The spigot end was then turned using one of those infinitely flexible Mircona parting off tools, before the whole lot was finally parted from the stock metal with the same parting tool.

Nicely done Ade! :clap: :clap:

They'll solve the minor teething problem. :thumbup:
