last night i checked the valve lash and some of the valves were off some had gotten loose and some had gotten tight so i re-adjusted them and noticed that as i moved to the other side of the motor some of the other ones that i had just set had changed. i find that really weird how i set them was to just bump the motor over until the valve next to the one i wanted to adjust started going down them i would adjust the one that was open. i can see that they might change a little after the inital start-up but after i had done the drivers side and i moved to the passenger side i noticed that some of the valves that were open on the drivers side had more than .025 lash. am i doing something wrong?
