When you say everything checked out no leaks... then leaked...
did you check it under pressure with nitrogen/ four oz r22 ?
or did you only check it under vacuum ?
Sometimes it will hold one direction but not the other.. slight movement of an oring can lose all your refrigerant charge.... of course the use of the correct color Nylog really helps too...
