I tried pulling all the pushrods.
I can only get halfway back due to the motor being in a tight space.
All the front ones were good.
I can't tell if the back 1s are good or not.
If the pushrods are bent, a valve is most likely bent.
I'll pull the isolator block and check the lines.
After some research, I know the 5.9Ls had tabs that broke and caused noise, but our 6.7Ls don't seem to have any tabs on the fuel lines.
I'm praying it's not a valve, but I think I would have other symptoms besides the noise from the fuel lines.
