I’ll try to work on something much more concise if you are gonna make it a sticky. I agree completely on searching, but this doesn’t seem to be happening and I’m pretty sure the length and progression of that thread is a big part of why, when everything people need to know could be put into a single post at the top.
I think just the title is the issue. Having 50 pages of documented failures is reassuring to me when I have it done as preventive maintenance. i can skim through 47 pages as long as the general consensus is to replace. I saw the crack, replaced before summer.
