Re: Valve lash settings?

As soon as polylock has finger tight resistance somewhere around another half turn.

Depends on your tolerance for NOISE!. 1/4 turn is recommended for racing(kinda noisy). Anything after that up to 1 full turn is ok. Generally the closer to 1 full turn the quiter.. Pick your poison...

Cold motor and set it with 1/4 turn pre-load warm motor why not run it and set it until noise goes away then 1/4 turn more. This a hydraulic cam right?

Preload

1/4 turn past zero lash, then set the set screw in the poly lock, then turn both the set screw and poly lock an additional 1/4 turn for a 1/2 turn total. This is what I do on the stand or in the car, cold or warm, hundreds of times.......minimal noise no further adjustments needed!
