I also have a leak in the low side ac valve it's this common.....it was arround 90s degress here in phoenix and turned the car on to check inpa on laptop and run engine for about 10 or 15 mnts and I heard a hissin noise
From engine so freon came out check with black light and was all over the low side inlet schrader valve line. Not sure if the heat create alot of pressure in the line to make it release the freon or what or maybe too much freon on line ?...so any input on this will apreciate. ....thanks again..
