360 sound good still?

I'm concerned about the "mildly froze" part. Put if they were able to break it loose than it may be fine.
When i first read this I thought you meant "froze" as in ice. But seeing you are in TX i guess not. I live in cold and ice country and have seen many times what "freezing" (as in cold) does to an engine, crack city and not just small cracks either some big gaping cracks too. This isn't what they meant by "mildly froze" is it?
