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.
Cheers!
Ade.

 :clap:  :clap:  :beer:  AdeV I have been following this thread with great interest superb job sir.
One point, on a high performance engine like this could the machining marks inside the sump slow down oil flow through the engine? would it make any difference if you polish out these marks so making the scavenge process of the oil more efficient.

If you cant fix it hit it with a bigger hammer

Cracking job Ade
A real credit to you :clap: :clap:
We used to polish (de bur) the inside of BDA race blocks
I dont think it made any differance to oil scavange but it did look good and cost nothing  :bugeye: :bugeye:

I've cut the end off it twice, but it's still too short
