GM actually makes a special tool made to center the seal on the crank pulley. The only way to do it w/o the tool is to put the crank pulley on and tighten the crank bolt BEFORE you tighten the timing cover bolts. Once the crank pulley is in place and tight, center your timing cover seal over the crank pulley, then slowly tighten the bottom bolts and work your way up.
