I doubt this will help you but when I disassembled my lq9 (same lifters as lq4) I checked the preload before I took it apart. It was around .130. I checked it over and over again, and counted the turns to zero lash 1 3/4 turns. Much more than I thought it would be. I'm not sure what the factory uses for preload spec but it must be deep.
