Valve springs
I'm having a valve spring replaced and I'm wondering if any of the unfortunate few that has had this happen if they had more failures latter on. I'm at 98K mile and wonder if they should all be replaced.

I replaced mine (I replaced only the broken one - I have a thread on it IIRC) and have had no more failures. Been a little over a year and a half. BUT, I don't drive it daily. IMO, I wouldn't worry but if you are worried, whatever bank is open just have that whole side replaced. The springs aren't that expensive and the rocker shaft has to be removed anyway (you could replace only that particular set on that bank).
I think it was related to a batch of bad springs due to metal quality issues. So, my thoughts in my instance are the bad spring with the bad metal issue broke and the others are okay, as they haven't broken and my truck has more miles on it since I replaced it.

I have only used the FORD OEM springs. They are pretty inexpensive and for me worth the piece of mind:

$8.33 each plus S&H

I have reused mine because I didn't have a new set at the time. They didn't leak as best I could tell.
They are also inexpensive so I have a brand new set for the next time I have to remove the valve cover.
