    How did you adjust the lifters? It's been determined that we should
leave them looser then originally called for. The reason is so that they can
bleed themselves of the air. Boston Bob Daniels recently sent a post about
it. Craw back under your van and instead of 2 turns after contact or
whatever it was, stop right there or one half turn more. Search the archives
and for more specifics.
