Leak?

Postby mytown » Tue Jul 03, 2018 10:43 am

Before I give up or start over I'd like to verify that the hissing sound in the video below is that of a leak and not some normal process. It is coming from near the orifice tube which I replaced. I was surprised to hear it since I drew down vacuum and the vacuum held for an hour. I then recharged the system and the ac is blowing cold.

The sound ends about 30 seconds after shutting off the engine.
