any suggestions on a good way to do this without getting oil everywhere? i'd rather do it with the engine off if possible, but i cant figure out a good way to get all the lifters right, one person told me to tighten until i feel a drag on the pushrods, then another 1/2 turn. well i attempted that method, and i could see the valves starting to open after the 1/2 turn, so that way isn't gonna work. any suggestions?

Is it a Solid or Hydraulic Lifter?
