ABH Moto holder torn down

Hello.

I have a question. I've got a 4.2L ABH engine out of a 93V8 engine. is ABH008XXX).
Unfortunately, the mounts for the climate compressor and a thread for the motor mount on the left (in the direction of travel) are torn off. It sits not far between the second and third cylinders of the left bench.
At least I'd like to weld the motor holder back on. Maybe. any experience with such repairs? Is that even possible?
Material is AlSi17Cu4Mg.
