AC high pressure relief valve question
Hey guys. New to the forums, just got a 92 Civic DX from my girlfriend. Car runs great. I do have one problem tho:
The AC is not working. A little background:
When my gf had it, it blew cold but not THAT cold. Finally, about two weeks ago, it just started blowing hot, no cold at all. So, I figured that maybe it just needed a recharge. As I am recharging it, I notice that the refrigerant/oil is just spewing out of the side of the compressor. I then checked and found it to be the relief valve. The rubber "stopper" was not attached to the valve.
Today, I decided to put the rubber stopper back on, have the system evacuated and see if that was all it needed. However, the guy I took it to for the evacuation said that it just kept sucking out "freon" even past the maximum capacity of 22 ounces. He believes that it's just sucking out air.
My question is this: When the relief valve blows/activates does it have to be completely removed and replaced? Could that be where the air is coming in from?
It's an old car, low miles, but I just don't really wanna spend 500+ on putting in a new compressor. So, I am trying to decide before I purchase the $80 dealer part (the relief valve) if I am right in thinking that once the valve opens, it's destroyed and must be replaced.
Thanks for any input!
