curious about valve lash setting/check

It's not back and forth on the pushrods. It's up and down. Up towards the rocker and down towards the lifter. Get all of that up and down slack out with the cam on the base circle, then tighten "whatever amount" you feel comfortable with for preload.
that's what I meant, it was late for me. do you have any input on why I would have pressure on those 3 valves? intake 5, intake 7, exhaust 7
I'm probably wrong, but my thought was.....those 3 valves may have gotten oil when I started it the other night? but I'm just guessing there.
