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

I set hyd lifter lash with the intake off, lifters dry, you can see what's going on that way be visually certain of the base circle.

Once fired up and lifters get fed oil, you can ,if even necessary, pre load them more if any make noise while it's running.

No one needs to be soaking lifters in oil or pumping them up before break in. Don't let the noise scare you. Lol
