So first hiccup built my motor up 7k miles ago and the valve seals have failed, heads were completely gone thru, but the Viton seal came off the holder and is all the way at the top of the valve on every other valve.
Mines a Victor reinz version of that apparently ford just came out with a new version. What would cause that many of them to pop off the steel cup the viton and rings are still together but at the top of the valve against the spring retainers. Has anyone else had this happen.
