Re: rocker torque

There is no rocker arm torque, you adjust the hydraulic lifters to zero lash and then tighten adjusting nut 1/2 to 3/4 turn max.

Re: rocker torque

Be sure the lifter is on the base circle of the cam, then tighten the rocker nut until the pushrod goes snug while rotating it between your fingers, then tighten another 1/4 to 1/2 turn.

Re: rocker torque

I always heard to run them out till they clack, then tighten them till they stop and another 1/4 turn. This was from my race car budds for their street cars that have hydrollic lifters but i thought that was the best way to do it.
