Looks like it bolts to that flange, literally right next to it is a 10mm looking nut and I bet that's what's clamping it down into some other flange.

If so it's likely an o-ring.

No I think the o-ring is probably shot, if it's already drained out then pressure test the system and spray it down to find exactly where it's leaking from and fix it.

Then vac, inject oil, and refill R134.

Yes if you discharge the AC system you should add oil back to it. All HVAC systems use both refrigerant and oil. When the system is discharged you have lost oil, it comes out with the refrigerant. Replacing major components like the compressor, evaporator, condenser you would add more oil. If you just discharged the system and are refilling then just add 1 oz.

1 oz of PAG 46 oil.

Most oil injectors are 2oz and will have graduated markings on the side, fill it over your mark then screw it in until you hit the correct 1oz mark.

Alternatively if you're just planning on ghetto filling the system with AC pro you can buy the ones that already have oil in them. I would read the bottle to find out HOW MUCH oil you are adding though you really don't need to add more than 1 oz or you're just wasting volume that would be better used with more refrigerant.

Just be aware that if you don't PROPERLY fill the system (vacuum, oil, add pure R134a) then you WILL have moisture in the system and your compressor will only last a few years. You can get a cheapo vac on Amazon, I use this one.

Can't remember for sure but I think I needed another bottle adapter for either the self-sealing or the non-self sealing ones. Can't remember which though.

i changed the gasket and now its not leaking r134a but it sounds like air is escaping in the same area still would the gasket be too big or would it be
another issue

You need to test for a leak with soapy water. Bubble solution (kids toy aisle in nearly every supermarket) works the best. Put it in a spray bottle and spray down the fitting while the AC is running.e

If it's a big leak it will literally start blowing bubbles, if it's a small leak it will make "white foam".
