How to adjust roller rockers w/ hydraulic cam. First start up.

For an LA engine and shaft rocker system and standard cam bearings, yes. I find I have to move the crank about 10 degrees at a time and run the drill for a bit; eventually you hit the spot. It can take quite few seconds to fill the rocker shafts and see the oil coming out even when you hit the right spots. The left and right sides oil at different crank angles.
