3.0 cam synchronizer problems

If you take the cam synchro out then turn the motor to top dead center without a synchro in it can you mess it up?

Rotate the (1) crankshaft until the No.1 cylinder is at TDC of the compression stroke and the (2) TDC mark lines up with the (3) timing mark. CAUTION: Do not turn the crankshaft or the camshaft during the removal and installation procedure or the fuel system timing will be out of time with the engine and possibly cause engine damage.
