No leaks, both ports have the same pressure with it off. The compressor is about 12-14 years old and sat the last year hanging clutch end up while the engine was being rebuilt.

No pieces of metal visible and it's still locked up. Got a quick clean done and new installed. So far it's holding vacuum. Do you have the approximate weight of 134a reported to go in?
