Hmm I never thought about giving stop leak a try...I don't want to ruin anything else in the system due to the stop leak. Any thoughts on this?

Also, if I were to test this, do I need to add more r134a oil into the system? The indy shop pulled all the refridgerant out when he was working on it, so does that mean it also pulled out all the oil? Any way to test this?
