    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    Looks like someone tried to seal a leak.

    I've never seen it but my first thought was that there was water inside and it froze.

    to me looks like someone did not see the service wrench insert was still in there and put thr cap on and tightened it down way to much and punched a hole thru the soft brass.

    No, haha, never saw that either. I'm going with water in the stem, (full to the brim) and then cap tightened. Then froze. In fact I'm going to do that intentionally on my personal condensing unit just to see if it happens It will freeze soon. I have to replace my unit next spring anyhow, dog peed all over the fins. Better sacrificing my unit for science than a customers

    Water freezing looks about right. The damage came from the inside so that's about the most logical thing I can think of.

    Pretty common on walk in freezers of the heat craft group, they use those same valves on the tin can and scroll condensing units.

    They usally just split on that outer seam, the star cracks in the middle are not as common. Soap bubbles or water in there will get it done quick at freezer temps. A -10 freezer is going to flirt with 0 degree return vapor temps and the frost, melt cycle will leave water inside a loose cap.
