You must not take up all the play of a soft lifter to quiet it down. Fist, it defeats the purpose. 2nd, it will significantly throw off the rocker arm geometry which if bad enoiugh can wear the valve tip and valve guides. Adjust it properly, and if it really never quiets down then remove, dissemble and clean it or replace it.
