Default 91 Lexus LS400 AC Leak

I have a 91 Lexus that has a serious AC leak, I put a can of coolant with dye to try and find the leak. Let be serious its a hole and not a leak. I got a UV flashlight and looked on the driver side of the engine where there seems to be to L shaped fittings it looks like thats where it is comming from. What AC parts are in this area. I also have cell phone video of the area but I don't think it will do any good. Any recommendations?

The AC compressor is on the drivers side where you are describing a leak. It is fairly common to need new hoses or O-rings to keep things sealed. It could also be that your AC compressor is worn out.

Are you running R12 or R134?
