What is the valve lash supposed to be on the Crane gold 1.8 Rockers for an LS1???

 

Very nice rocker arm set. I installed them on the 408 in our Tahoe. I don't know to be exact, but there is a series in how they want you to adjust them. It explains it very well in the directions. If you do not have them give me a call and I will get Crane to fax them to you.

 

first i'll assume you are using a hydraulic cam. as per VHP, the people that helped in designing the rockers with Crane, you want about .060-.120 preload on the lifters. how far down the lifter plunger is pushed down into the lifter. there is zero 'lash' on a hydraulic cam. lash term is used on solid lifter cams. where you have an amount of gap between the rocker and valve tip.

 

Instructions call for zero lash.
