Roller Rocker arm adjustment

[BlueBull]

I’ve used this method several times with good results on hydraulic lifters. Adjust to zero lash and then about ¾ of a turn to preload the lifter.

“Rocks” means that exhaust valve is just about to close and the intake valve is just about to open. Both valves are in motion.

When this happens the piston in the table column “adjust cylinder” is at the end of the compression stroke and the lifters are on the heal of the cam lobes.

I'm not sure this method having any disadvantages but I used it without problems.
