Just fired the ol' girl up. I do see bubbles - foam in the sight glass. I just let it run for a few seconds. Is that bad?

Assuming the R-12 is close or OK, will I hurt anything until I add another 4 oz of oil ? I am hoping VSTECH has the recovery equipment and I will drive to his house this week for a re-do of the oil and R-12.

Bubbles mean that the refrigerant is low.
