These shaft rockers are Harlan Sharp which have been on this engine for the last 4 years without any problems . They are tightened by hand , but not crammed down and the final adjustment is checked after the lash adjuster is tightened . We have a lot of experience using these rockers , and never had this problem . So that is why we are asking if other folks have had this problem . BTW , why would over torqueing the adjuster nut cause the lash to close up ?
