I couldn't find it in the FSM. I'm having valve clearance issues. The guides for each rocker arms are not allowing enough clearance between the rocker and cam, and are keeping my valves open, killing my compression. The problem is that they only make one size guide, so this shouldn't even be an issue. The shop I took my head to says they didn't mess with the valves, just checked it to make sure it sealed and that it wasn't warped. Any ideas guys?
