Will a freeze plug bottom out?
When driving a freeze plug into the block.....is there a "too far"? Will it push all the way through, or is there a point where it simply goes no further?

Wasn't actually installing a new one.....I was tapping the old one in to see how far down the radius the crack in my block extended. 
I moved it in almost 1/8" and the crack is still going, so I stopped there and buried it in JB Weld.
Merry freakin Christmas to me

cookie, Can I ask a dumb question? With $20 a gallon coolant, How did your block get cracked? I am not sure about the welding thing. I'm sure someone could effect a weld that would hold for a while, but you will always be having trouble from that thing and you will always worry about your mule coming up lame. 
Maybe somebody has a better idea.

Welding that big mass of metal takes some work. You have to heat the area around it so it stays hot while welding it. Otherwise, right after your done with the weld, the surrounding area will suck the heat very quickly and most likely will crack again. There's some excellent epoxy on the market for cracked blocks. I think we used a epoxy called Devcon, it was 24 years ago and my memory's not quite what it used to be (stupid beer). We used it to seal up a John Deere tractor that had a 9" x 9" U shaped section of block cracked and pushed out. Never leaked after we used the epoxy.

I have used a product called KW Blockseal with excellent success. you flush your cooling system to remove all anti freeze. then fill er back up with water and block seal. run until hot, drain and let sit overnite. ran this stuff in my mack truck for 4 years and not a drop has leaked. hope this helps.

Hey Cookie, so your saying that the crack is in the radius of the freeze plug hole? If that is the situation, can the hole be bored to accept a larger diameter plug, hopefully removing the cracked portion in the boring process. I dunno, just a thought, aloha.
