Is this fixable, or not?
Hi I was given this case recently as shown in photo, where the crank bearing sits there is damage can this be machined/fixed or throw it in bin?

Best off take it to a VW machine shop and let them look at it, in my opinion I wouldn't risk it, that hole retains the locating pin for the main
bearing, its a recipe for a spun bearing.

What type of case? early or late twin relief valve? whats the engine code? I'm not a machinist, but happy to look at it and do a few measurements for
you. But it doesn't look good.

Looks too far gone to even ream out and use a step dowel in.
Any history on the block? like how the hell a US engine ended up in aus?
Has it got a fuel pump mount? AJ engines were fuel injected and didnt have the stock fuel pump mount

As I said it was given to me by a mate, he does 'nt know anything about it all I know is it had what looks like standard bearings in the case.
No fuel pump mount.
Thanks for your help guys I'll take it to a machine shop tommorow see whait they say.
Pity would have been good I think other wise.

I have used this stuff. It works really well if you get the process right. As the video shows, if you get the process right the welds are very strong.
I welded some alloy tubing to alloy plate and then tried to smash the tubing off. I couldn't break the weld, just collapsed the tubing.
But on another project, I obviously didn't do it right and the weld broke. It is also very difficult to weld two different types of alloy together as
one might start to bubble (get too hot) while the other is not hot enough to melt the rod. Obviously someone with more experience and skill than
myself would be able to do a better job.

I only have a MAPP gas torch, I would think you would need a oxcy torch to be able to get enough heat into the gearbox housing, but yes, it should
work fine for fixing the weird holes !!! :-)

magnesium alloy is very difficult to weld so just chuck it on the fire and you'll get some nice fireworks.
throw some water on it when it burns  just make sure you wear a few welding masks

If theres nothing else wrong with the block I have heard of guys redrilling to put the dowel in the same spot in the other half of the case.
Not ideal but if it keeps an engine going might be worth a shot.
