rocker arms

  1. Might have a Broken rocker

    6.4 Motor Problems
    I'm taking a guess on having a broken rocker, what's your guys thoughts? 08 F250 6.4l. It's got a dpf and egr delete, sct tuned with IDP custom tune. I noticed a sounds coming what seemed to be threw the intake, a popping sound, also I can hear some tapping/rattle on the passenger side valve...
