Hi Scotty,

Recently I replaced my condenser and being the first time I properly recharged, I encountered some gray areas along the way that weren't explained too well in the many videos I have watched. I purchased an ac manifold gauge set to do the job and rented a vacuum pump to do things right. So I got a vacuum on my vehicle for about an hour and then I added my refrigerant through the low pressure port. I learned that when you replace big parts like that, you want to add compressor oil but I'm not sure exactly how that is done. ChrisFix said to just pour it through the refrigerant hose but when I did that, it didn't feed through the tube. I am not sure if it's ok to open up the low port when the hose is exposed to the outside environment so I dumped it. Since I was in a time crunch I just filled the refrigerant and figured i can fill oil later. Also, was wondering if I could run a vacuum pump after the system has been charged with refrigerant. Lastly, I still need to add roughly 3.4 oz of refrigerant. How worried should I be that I'm damaging anything without having added the recommended 1 oz of oil and the last 3.4 oz of refrigerant?

you can't vacuum after adding refrigerant or you will suck it all out. I use an injector, like a giant needle, to put oil in a system, you can buy one and guess how much to put in, as it's just educated guesswork unless entire system is flushed empty then refill with a factory load
