Yep, I personally found that out when I lived in Wisconsin with 1 of my 440 engine blocks.Correct me if I am wrong, but I think those plugs are for the casting process, not freezing.
Agreed, and I speak from experience. I've used them in a pinch. They're OK for a temporary repair; they aren't suitable to rely on as a permanent fix. And man, if they get crooked and swell up like that, they can be nearly impossible to remove, and the whole while it's sitting there dripping coolant on your face while you're fighting to pry it out of the block. Been there, done that, screw that.DON'T DO IT! Rubber freeze plugs are garbage. If you have to pull the motor to replace the freeze plug, guess what you need to do. The only way I'd ever use a rubber freeze plug is if the truck were stranded a hundred miles from nowhere and I needed to drive it to the nearest town to put in a metal plug. Even then, I'd just try and get a tow.
