Thread: Colapsed Lifter?

The lifters should all have some pre load on them. You shouldn't have any rocker arms that are "loose", that is with up & down play. You'll need new bolts or get some reusable rocker arm bolts. Clean the bolt holes with some carb cleaner then some canned compressed air like you use on your keyboard, to ensure they will tighten down all the way. Torque the bolts to 18 ft/lbs and then an additional 1/4 turn. The tightening requirements are different for reusable bolts not sure on the specs for them.
