I'm new to the 4.0 Ford but from what i've read its not uncommon for them to have excessive valvetrain wear/noise. Mine does this, not terrible, but it bothers me. What is the fix? Is it the rocker arms and shafts that get wore? My truck has 141k miles, but i believe the engine has been rebuilt. I just bought it but it looks as though the block, heads, water pump, and valve covers are all freshly painted gray. I can only assume it has been rebuilt/replaced not too long ago...
