hello ev1, I have a black mazda 929 that has been giving me the same blues with the a/c line leaking for over a year. the line im speaking of is the line that goes from the condenser to the dryer. I have tried over and over using different o-rings multiple o-rings,and even no o-rings but they all give me the same result as soon as I add freon.I can see it bubbling and leaking right on the spot where the a/c line and condenser connects.I even purchased another used condenser b/c I thought maybe mine was cracked,but I got the same result. Is it possible that the a/c line can be warped or something.i think im running out of ideas . can anyone tell me if there is a special seal or o-ring to use or what im doing wrong.i though about taking the condenser out and then bolt the line on good and snug,then drop the conder back in with that line already attached. starting to get desperate.
thanks ev1 for your help and advice. be safe
