Y-Block rockers
I have a 57 with a 312 that has two types of rocker adjusters, some are the threaded adjuster with a lock nut and the others are hollow that are supposed to have an interference thread. Some of the latter can be turned with my fingers so they won't stay adjusted. There is not enough thread showing to use a jam nut, not even a thin one. I considered using a sharp chisel to interrupt the threads or cleaning squeaky clean and using a drop of blue Loc-Tite to lock into place. Any suggestions will be appreciated or maybe new rockers is the only solution. Thank you.
