How do you adjust lifters on 5.7?

Answer 1

I'm assuming the 5.7 your asking about is a 350 Chevy. It's not very easy to do. There are two ways. The first way is to remove the valve cover. they make a tool that you can clip on the top of the rocker arms to stop the oil from splasking everywhere. You will need a ratchet with a 5/8" deep barrell socket. start the engine with the cover off and you will need to back off or loosen the nut on the rocker shaft until you can hear it tapping. Stop and tighten it just until it stops tapping. Do that fifteen more times and that's it. You can cold lash the valves if you have the hands for it. I have always taken the valve covers off and loosen the rocker ars while feeling the pushrod for slack. When I get slack I stop and slowly tighten the nut while spinning the pushrod between my fingers when I feel it get snug, I stop and tighten it an additional 1/2 turn on an older lifter or a full turn on a new engine.
