I'm service'n my A/C today with R-134a like it calls for. all of a sudden the compressor on the back side starts kicking it out. scared the crap out of me. WTF did I just do? everytime the compressor kicks on it squirts it out? any help would be appreciated

fixed it. there's a high pressure relief valve on the back of the compressor. take your service hose without the can and hook it back up to the low pressure side. leave the truck off. vent some pressure out. point the service hose toward the side. don't want that crap in your face. should be good to go after that. i must admit it scared the crap out of me. i don't like to hear noises like that coming from the engine.
