i wouldn't use slick 50 because the teflon tends to plug up the filter prematurely. the tapping is probably wear on the bearings,when the oil is cold its thicker and takes up the extra cleance then as it warms up it thins out causeing the clearance to show up. either replace bearing or keep driving it,it'll go 200,000 easy if you change oil every 3000,ticking noises and all. just for the hell of it my wifes old tired 3.8 went 220,000 (got rid of it,but was still running).she ran it out of oil at least once a month(we were beating it into the ground,wasn't worth rebuilding).this thing would tick with a slight hint of a knock but ran strong even when we sold it.still haven't figured out why it never blew up or seized.
