Freeze plug issues

There's also a 3 piece brass plug that has a nut you'll tighten in its center to expand it. I've had a lot of good results with those over the years. And when a rear plug is dripping on one side I usually find the same location on opposite side damp. So weak that I could poke my screw driver through it. One becomes 2 or even 4 ( my last rodeo ).
