  2. 6.4 Motor Problems
    Hey guys, so I'm about to replace all my rocker arms on the passener bank of cylinders. I'm kinda confused on some stuff tho, like setting valve lash, ect. Do I just put each assembly on and adjust valve lash to spec? Or do I have to make sure surtain cylinders are on Top dead center or not...
