Default A/c compressor leaking?

OK so after having some work done on our 03 pt cruiser, the mechanics failed to put a gasket in at the evaporator and all the refrigerant leaked out. I fixed it and the ac worked great for a while, but then it discharged. We thought this was the hose because she had hit a curb and not told me a week back, but after she had her father in law replace the hose it is still discharging. I ran it for a little and video'd the result. You can see it's leaking from that valve looking thing on the bottom of the compressor. I dont know what my next move is.

Any ideas why its doing this?

If I'm not mistaken, that's the high pressure valve and you'll need to replace it. Unlike the recycling valve on top of the accumulator which doesn't loose any R134a when changing it, the high pressure valve vents everything...and it's illegal to just let it out in the atmosphere.

just went and checked my old compressor that i replaced last week and found out it is size 14 wrench, but couldnt find any auto part store online that sells it ! it must be a dealer item !!
remember to add pag oil 46 (double check though as my pt is 2006 ) since you lost some

can this valve considered compressor oil drain valve ?! in case you wanted to drain the oil and replace it ?! it is the lowest piont in the system

Can someone walk me through the change or is it just remove old valve, replace, oil, and recharge?

There's too many different kinds of valves for me to help. Not sure which fits the PT compressor, and as far as replacing the old one, by law the old R134a should be captured and not vent into the atmosphere so unless you have the right equipment it should be done by a shop that does.

Ok so looking at the compressor it says 10s17c 47220 3673
3G 1843
HFC134a
in googling those i found the 10s17c to be fairly common but nothing lists the valve information. I can only find them to buy.

Have you tried just going to a Chrysler dealer with all your car information and buy one from them?
