I found this answer for Poulan saw. Maybe it will work for your homelite:
...on your leaky craftsman pull the chain and bar and there is a cheap tin foil looking cover for the oiler... We just repaired one for the same problem and found a hunk of oak bark had gotten in behin and was aloowing it to empty the oil tank in a few days... so far so good...he uses it for pruning smaller trees in his business.... Good luck on the repair as I said that tin foilly looking thingy was a pure pain to get off abd reinstall...I was
told by a poulan mech to get a new one for a few bucks........the cover that is....
