    Lash adjustment with jessel

    Getting ready to run a solid roller for the first time, i'm also using a jessel shaft mounted rocker system for the first time,i've been told they will hold the lash setting longer than stud mounted rockers is this true?

    The Jesel system we have on a BBC is rock solid. The only time we saw any movement on them is when we started to lose a lifter.

    If you adjust any of them right, none will lose it. I can run my valves twice a year and maybe adjust one. I have stud mounted rockers and a stud girtle. With a roller cam.

    adjust lash the same with and without a shaft system, i suggest setting them running it for awhile 15-20mins and checking again. Then after the first time it see's higher rpms check again.

    Best tihng to do is check them at every oil change .. easy to do

    You can check/adjust just like any other rocker arm, the difference is you'll be just checking.


    I ran mine (T&D) all year and never made one adjustment.
