Leaking a.c. compressor

I have aluminum threads on my a.c
(Long story short )Sanden compressor that I messed up . Its leaking compressor oil now. I'm guessing thread sealant is a no go for an a.c. system. Is there anything I can do ? I guess they're pipe threads ???? I'd have to figure out what threads they are and buy a die. You know how aluminum is - very flaky.

Which compressor cylinder head is it? Probably easier to just replace the bad head.

M or K. That's not bad. What happens when you take the head off ? Granted the refrigerant will be evacuated and you'll have to put a vacuum on it after. Will a bunch of oil come out ?

Heck yeah except I think I might have to take the compressor off to do that .I have to make sure the head is mounted on the back end and not top side. If it's just on the back I'll have to take it off or oil will spill everywhere.

My head is mounted vertically so I'd have to remove the whole compressor to replace it. I could do it . But of I can use a sealer that would be good.

I found the problem. The o-ring was shaved s little The compressor head's male fitting threads had a big chip where the o-ring sits but there was still meat on there for the o-ring to sit . So I was just careful tightening it down -we shall see.
