Went on a call for a warm 2 door reach in freezer. Found low charge. I had actually topped this thing up 6 months ago or so. At the time I found lots of oil around the k-body compressor so i tightened all the bolts etc.
This time I decided to scrub everything down and try finding the leak again since tightening the bolts didn't work. I sprayed it down with simple green and noticed bubbles coming from a crack in the oil pump housing. The crack was in the middle of the part, it did not go to an edge. Never seen anything like this before.
This is a 2 year old copeland factory rebuild that was installed by a competitor. I assume it was either a casting flaw or the compressor got dropped on the oil pump. I ordered a new pump housing.
Anyone ever seen something like this before?
