I thought you actually had a couple of them back there...

Although logic might dictate your statement to be 100% correct, there are proven instances where it actually has worked for others - for years on end. Regardless, my little JB Weld approach was not intended to act as a permanent solution, nor did I expect it would/could serve as such. It was indeed intended to be temporary just to get me through the summer (maybe a little longer if I was lucky).bridge47":3q98fdk3 said:-JB weld does not seal against pressure. Ever.
It did - but not in the JB Weld patched area. The patch actually built pressure back into the coolant chambers, ultimately revealing even more fractures in the back of the block. I cannot say specifically where - at this point it didn't much matter to me anymore. I decided to take 'er off the road until I could ultimately source a replacement block, hence my latest post.bridge47":3q98fdk3 said:When your block starts leaking again(and it will),
Trust me, I wouldn't have deliberately disregarded the coolant mixture thinking these plugs (even if they were truly "freeze" plugs), would cover my butt in the event of freezing. Despite how positive I was that the mixture was proper, it apparently was not. Still kicking myself for this.bridge47":3q98fdk3 said:Don't count on cold temps to push them out. Not what they were designed for.

The heat stresses in this corner of the block are huge!
When i finally pulled by block down (had been running it with the crack for ~4 months), the section that had cracked had a ~1mm lip on it. I was amazed it could deform that far.
