Outer Limits 4x4 Board

Hi,
Can any one help with this problem on my mums Paj. Its a 3.0L V6 with a fairly dramatic air con leak (bad enough you can see AC oil welling up. Images show where the leak comes from.

Is this a part that can be removed, cleaned and re-sealed. Or is it a replaceable part or a replace the whole compressor job?

Cheers

Don't know but it might be worth asking this under General or someplace else as Air con units are pretty common.

Cheers!

I'll give it a shot in gen tech.
