Ls1 Engine Build Rockers

The instructions included with the rockers list a proper preload operating range of .25 to 2 turns on the lash adjuster. Jesel specifies one full turn is the ideal location for the adjuster, so before beginning any measurements, we loosen the adjuster's lock nut, back the adjuster all the way out until it can't turn any more (the adjuster being all the way up in its bore), and rotate one full turn using an Allen key. The adjuster's lock nut is then tightened so that the adjuster will remain at one full turn while we perform our measurements.
