A/C Spewing Freon out valve after recharge

[AmosCake]

Tried recharging my ac but as soon as I take out the can from the valve, it starts spewing it back out? Or it could be oil/dye? Not sure why this is happening.

You probably need to replace the schrader valve core. You local auto parts store should be able to help you.

The valves have a rubber seal in them that hardens and cracks with age. Vac it out, replace the valve (id do both) and vac/charge it again.

Cool thanks guys

stupid question gets stupid answers but... are you recharging with r12 or did you update your system to r134a + appropriate seals etc?
