So my a/c is leaking at least out of the low side service port. I am planning on fixing. I have the vacuum pump and gauges. Im going to replace the service shrader valves and pull vacuum and recharge. My question is how much (by weight) refrigerant do I put it in it? I have been unable to easily find the amount searching around for a 98 Yukon WITHOUT rear air. Im assuming it would be the same as any 98 silverado/sierra, can anyone provide me the amount of refrigerant by weight please? Also, see the attached media file. You can see the oil bubbling out of the leak. Is that a concern? Does oil need to be added? I dont want to add too much of course. Any input from some experienced a/c folks?
EDIT: click on the this image and watch the video on imgur. should the oil be bubbling there? should it be at that point in the system or only in the compressor?
