Found this just 10 days after a repair on a 5' section 4 1/8" suction line going through the ceiling. It's an R-22 system. 2nd picture is the wall facing the unit. Needed 3 gallons of oil as well. Third and fourth pictures are the "original" problem...condensor making noise...mmmm...where's the missing fan? Oh, here it is, in the condensor coil...still running!
