What you are saying is helpful but unfortunately I need an explanation as to what you mean by oil pick-up. Can you dumb it down a bit as I am not familiar.
Do you mean aluminium plugs are the only way to clean properly or do you mean drilling a hole in the gallery is the only way to clean them properly? Where do you get aluminium plugs from?
The oil pickup is the tube that oil gets sucked into by the oil pump. It's a kind of press-fit into the gallery where your weird crack is. Tapping for a setscrew as @Zed suggests should bung it up. (the hole, not the pickup )
Folk remove the small core plugs in the case to clean it. I wouldn't recommend doing this. In your case as above a small setscrew into the side of the gallery should be fine.
Different to your situation but you can remove vw's press fit plugs from the end of the oil gakleries on a case then just tap a thread in the case and screw a tapered thread plug in. If your hole is drillable should be a similar fix. I got a selection off eBay bsp thread hex key plugs..

It’s been dropped or had the jack on it.Drop it,strip it and get it welded. May as well put some new rings in,while you’re at it.
Same way every other stud nut and bolt on the engine does. Well done, you managed to repeat the OP's answer to my question all by yourself.
I am going to try drilling, tapping and plugging as you suggested the hole. Maybe M6. I have re-read all the posts. Just so I fully understand. 1. When I am carefully drilling, am I going to go through the alloy case and then hit this oil gallery insert tube? If so should I also drill through that? 2. What type of set screw would you recommend, stainless or bzp or? 3. If there is a pick-up tube liner in this part of the case is the crack likely through the liner or is the oil coming somehow from between the liner and the gallery? thanks for your patience in explaining, I am try to picture what is inside and what is going on.
There's no liner. The pickup tube joins that big oil gallery at about 90* a bit further downstream. The gallery is a dead end, plugged with the core plug you can see at the end. You'll just drill through about 3mm of oil gallery wall. It will be full of oil, so drain it first and stick grease on the drill and tap to catch any particles. Any small setscrew will do. Drill, tap and loctite it in. I'll try and find a pic of that case half. It's very simple inside.
PS I'd start with a 3mm drill to get feel of it. If you can find a suitable plug, I'd go for aluminium, as the coeff of expansion is close to that of the magnesium case.
Best I can find (from the other side), not very useful. The oil pickup feeds into the big oil gallery.
It looks to be roughly where the large pickup gallery T's off the the oil pump so it should be well clear of the pickup tube. Here's another photo - they never show quite enough!
Not going to end well .. If it’s cracked it’s likely bigger than a M6 bolt .. which you still have to seal .. I would start it and film it to see .. die grind the surface clean then chemical metal it ..
